Abstract
Abstract.Background: Increasing rail transportation requires appropriate railway suicide preventive measures. Aims: The investigation of trends in railway suicide during 2008–2018, a period in which preventive measures were taken by Dutch railway infrastructure manager ProRail. Methods: Generalized linear regression models for railway suicide were developed for the period 1970–2007 with general suicide rate, railway traffic intensity, and a combination of these variables as regressors. Subsequently, the best-fitting model was used to investigate trends in railway suicide after 2007 by comparing in retrospect observed values with the expected outcomes of the regression model. Results: An adequate regression model for railway suicide was obtained using both general suicide rate and railway traffic intensity as regressors. Based on this model, while national suicide mortality and railway traffic increased, a distinct relative decline in railway suicides was found from 2012 onward. Conclusions: This decline of railway suicides in the Netherlands may indicate that preventive measures taken by ProRail were effective and prevented around 85 railway suicides annually, a reduction of 30%.

Abstract
OBJECTIVE Public transportation workers are exposed to higher levels of stress related to accidents, injuries, and person-under-train events when compared to other workers. This systematic review integrates the existing literature on mental health among high-risk public transportation workers to estimate the prevalence of post-traumatic stress disorder (PTSD), major depressive and anxiety symptoms following critical incidents while on duty. METHODS This systematic review is part of a larger systematic review which examines mental health and work outcomes of individuals working in professions at high risk of critical incident exposure, i.e., high-risk professions. Articles were included if they measured the prevalence of PTSD, Major Depressive Disorder (MDD) and Anxiety Disorder (AD) in a transportation population following exposure to a major incident, for example, a person-under-a-train. RESULTS Among the ten articles, all reported prevalence of PTSD which ranged from 0.73 to 29.9%. Four articles reported prevalence of depression among transportation workers exposed to a critical incident and prevalence outcomes ranged from 0.05 to 16.3%. Only two reported prevalence of anxiety from 1.3 to 13.9%. CONCLUSIONS This literature reports that transportation workers are prone to involvement in traumatic accidents leading to higher rates of PTSD compared to the general population. Strategies to reduce transportation accidents and to provide transportation workers follow-up mental health support is needed for this vulnerable population.

Abstract
Objective: Underground drivers face a considerable risk of running over suicide jumpers on the tracks during their career. These traumatic exposures may lead to major psychological sequelae. Methods: Within an outpatient setting, 50 drivers were consecutively enrolled in a prospective non-controlled trial. A low-intensity, stepped-care approach included: emergency care immediately after the critical accident, comprehensive assessment with a structured clinical interview using the following scales within three days: Composite International Diagnostic Interview (CIDI), Impact of Event Scale (IES), Screening for Somatoform Disorders (SOMS), and Cologne Trauma Inventory (KTI). Results: During a 2-year period, 50 subway drivers were exposed to 66 serious critical accidents (deaths: 39, severe injuries: 27). Rate of acute stress reactions was 48%; rate of acute stress disorders was 30%. Scores of IES and SOMS were significantly increased correspondingly. At 1-month follow-up, PTSD was diagnosed in 24 (ICD-10) and in 9 drivers (DSM-IV), respectively. Major depression (n = 15) and somatoform disorder (n = 10) were diagnosed as coexistent to PTSD. Acute stress reaction/acute stress disorder, IES- and SOMS-scores, and previous traumatic exposures during adulthood, but not during childhood, were significantly associated with the risk of PTSD. A majority of drivers (n = 43) succeeded in reaching complete symptomatic remission and returning to work again within a 6-month period. Seven drivers suffered from long-lasting posttraumatic symptoms causing severe social impairment. Conclusions: A low-intensity, outpatient stepped-care approach may provide support to traumatized underground drivers in their process of posttraumatic remission and recovery.

Abstract
BACKGROUND Metro suicide can cause tremendous effects on the general public. Platform screen doors (PSDs) have been identified as one of the most effective methods of suicide prevention at metro stations. However, there are few studies focusing on their effectiveness in preventing suicides. In particular, the effect of types of PSDs, including full-height and half-height PSDs, has rarely been assessed and compared. METHODS Based on the suicide data provided by the Shanghai metro operator, the effectiveness of installing different types of PSDs for preventing metro suicides was investigated using a Poisson regression model. Ten-year monthly panel data for 94 metro stations from 2008 to 2017 were used in this study. RESULTS The number of metro suicides declined by 90.9% after the PSDs were installed at metro stations. In addition, different types of PSDs had different effects on decreasing the number of suicides, and a higher half-height PSD was more effective in preventing suicides. Specifically, full-height PSDs could eliminate metro suicides by completely preventing passengers from entering the track area, while half-height PSDs that were 1.5 m and 1.2 m high could decrease the number of suicides by 79.2% and 60.2%, respectively. Moreover, there was no significant indication that the installation of PSDs at metro stations displaced suicides to railway stations without PSDs (p = 0.706). LIMITATION The potential economic benefits of different types of PSDs were not considered in our study. In addition, we did not examine whether suicide attempters would try to take their own lives by using other methods of suicide. CONCLUSION The installation of PSDs, especially full-height PSDs, could be very effective in preventing suicides at metro stations. Although half-height PSDs are less effective than full-height PSDs, increasing the height of half-height PSDs could be an effective way of enhancing their effectiveness in reducing the number of suicides.

Abstract
Railway suicide is a significant public health problem. In addition to the loss of lives, these suicides occur in public space, causing traumatization among train drivers and passengers, and significant public transport delays. Prevention efforts depend upon accurate knowledge of clustering phenomena across the railway network, and spatial risk factors. Factors such as proximity to psychiatric institutions have been discussed to impact on railway suicides, but analytic evaluations are scarce and limited. We identify 15 hotspots on the Austrian railway system while taking case location uncertainties into account. These hotspots represent 0.9% of the total track length (5916 km/3676 miles) that account for up to 17% of all railway suicides (N=1130). We model suicide locations on the network using a smoothed inhomogeneous Poisson process and validate it using randomization tests. We find that the density of psychiatric beds is a significant predictor of railway suicide. Further predictors are population density, multitrack structure and-less consistently-spatial socio-economic factors including total suicide rates. We evaluate the model for the identified hotspots and show that the actual influence of these variables differs across individual hotspots. This analysis provides important information for suicide prevention research and practice. We recommend structural separation of railway tracks from nearby psychiatric institutions to prevent railway suicide.

Abstract
This study investigated the geographic distribution of suicide and railway suicide in Belgium over 2008--2013 on local (i.e., district or arrondissement) level. There were differences in the regional distribution of suicide and railway suicides in Belgium over the study period. Principal component analysis identified three groups of correlations among population variables and socio-economic indicators, such as population density, unemployment, and age group distribution, on two components that helped explaining the variance of railway suicide at a local (arrondissement) level. This information is of particular importance to prevent suicides in high-risk areas on the Belgian railway network.

Railway suicide in England and Wales 2000-2013: a time-trends analysis. BMC Public Health 2016; 16:270.

Abstract
Background In 2010, the “Tackling Suicide on the Railways” programme was launched as a joint initiative among Network Rail, the Samaritans and other key organisations such as the British Transport Police and train operators to achieve a 20 % reduction in railway suicides from 2010 to 2015 in Great Britain. We report the most recent age and sex specific trends in railway suicide in England and Wales from 2000 to 2013 and examine whether the initiative’s target reduction in railway suicides is likely to be achieved. Methods Population data and suicide mortality data (all methods combined and railway) for England and Wales were obtained from the Office for National Statistics (ONS) and used to calculate age and gender specific rates for deaths registered from 2000 to 2013. Data on railway suicides were also obtained from the Rail Safety and Standards Board (RSSB) and compared with ONS data. We used joinpoint regression to identify changes in suicide trends across the study period. Results The railway was used in 4.1 % of all suicides in England and Wales (RSSB data were similar to ONS data for most years). Suicides in all persons from all causes decreased from 2000 to 2007, with small increases from 2008 until 2013; this rise was entirely due to an increase in male suicides. Railway suicide rates increased over the entire study period; the proportion of railway suicides in all persons increased from 3.5 to 4.9 % during the study period. This trend was also mainly driven by increases in male suicides as female railway suicide rates remained steady over time. The highest age specific railway suicide rates were observed in middle aged men and women. Although there was no conclusive evidence of an increase in ONS railway suicides, RSSB data showed a statistically significant increase in railway suicides in males from 2009 onwards. Conclusion The continued rise in male railway suicide in England and Wales is concerning, particularly due to the high economic costs and psychological trauma associated with these deaths. The initiative’s target of a 20 % reduction in railway suicide is unlikely to be achieved.

Abstract
INTRODUCTION We critically review research on railway suicides to inform suicide prevention initiatives and future studies, including who is at risk and why, and behaviours at track locations. METHOD Literature was identified from Scopus, Web of Science, Google Scholar and our documentation centre, and contacting 71 railway companies, resulting in 716 articles and eight unpublished reports, with 94 having empirical data on 55 unique studies. Research quality was critically assessed. RESULTS The quality of studies varies greatly with frequent shortcomings: no justification of sample size, lacking information on the reliability and validity of measures, no explanation nor theoretical understanding of findings. Railway suicides resemble closely people who use other methods, although they tend to be younger. As with other suicide methods, mental health problems are likely to be present. Railway suicide attempters usually die, but most urban transportation systems attempters survive. Railway suicides are rarely impulsive; people usually go to the railway for the purpose of killing themselves. Hotspots have been the focus of some prevention measures. We know little about why people choose railway suicide, but studies of survivors suggest they often thought they would have an immediate, certain and painless death. Media reports on railway suicides can increase their incidence. CONCLUSIONS Most research focuses on the incidence and characteristics of events and attempters. Research has not shown that railway suicides are different from suicides by other means. Better quality research is needed, particularly studies that investigate why people use railways to kill themselves and how railway suicides can be effectively prevented, as well as more evaluations of prevention programmes. Because of significant variations by country and region in characteristics of railway suicides, prevention programmes should conduct a local assessment of the characteristics of attempters and incidents. PRACTICAL IMPLICATIONS We need more research on indicators of suicide risk in attempters on railway property, and studies of how suicidal people on railway property are prevented from suicide. Changing beliefs and attitudes about railway suicides, reducing media reports, offering help onsite, controlling access at hotspots and better staff training in mental health facilities near tracks are promising prevention strategies. However, local specificities must be considered in planning prevention strategies.

Abstract
AIM This article presents a strategy to prevent trauma, support and care for railway personnel who experience critical incidents (CI) on the job, usually fatalities by accident or suicide. METHOD We reviewed all publications on CI management, support and care practices in the railway industry, as well as practices in place in Canada (unpublished protocols). Semi structured interviews were conducted with 40 train engineers and conductors involved in CIs and the content was coded and analysed quantitatively. RESULTS Employees' satisfaction with the help received after the incident varies according to the behaviour of the local manager, company officers and police, the level of compliance with existing company protocols to help them, the presence of unmet expectations for support and care, their perceived competency of clinicians they consulted and the level of trust toward their employers. CONCLUSION On the basis of the interview results, the review of existing railway practices and discussions with railway stakeholders, a model protocol was developed for a comprehensive workplace prevention, support and care protocol to reduce the negative impact of railway critical incidents on employees. This protocol includes preventive actions before traumatic events occur, immediate responses at the site of incident, interventions within the first few days after the incident and longer term support and interventions provided by the company and by outsourced experts.

Abstract
This review covers a central aspect in railway safety which is the prevention of suicides and trespassing accidents. The paper attempts to answer the following research question: 'What measures are available to reduce railway suicide and trespass, and what is the evidence for their effectiveness?' The review is based on 139 relevant publications, ranging from 1978 to 2014. The analysis aimed to identify the past and current trend in the prevention practice by looking both quantitatively and qualitatively at the recommended measures. According to the results, there has been a constant focus on suicide prevention, and only relatively recent interest in trespass countermeasures. The content analysis revealed 19 main preventative categories which include more than 100 specific measures. We identified 16 common categories against railway suicide and trespass, and 3 categories of specific measures to prevent suicide. There are only 22 studies which provide empirical support for the effectiveness of measures. Actual combinations of measures are barely evaluated, but several challenges emerge from the literature. The discussion focuses on the need for a unified approach to suicide and trespass prevention, and on the importance to consider the effect mechanism of the measures in order to design better interventions.

Abstract
BACKGROUND Suicide prediction during psychiatric in-patient treatment remains an unresolved challenge. AIMS To identify determinants of railway suicides in individuals receiving in-patient psychiatric treatment. METHOD The study population was drawn from patients admitted to six psychiatric hospitals in Germany during a 10-year period (1997-2006). Data from 101 railway suicide cases were compared with a control group of 101 discharged patients matched for age, gender and diagnosis. RESULTS Predictors of suicide were change of therapist (OR = 22.86, P = 0.004), suicidal ideation (OR = 7.92, P<0.001), negative or unchanged therapeutic course (OR = 7.73, P<0.001), need of polypharmaceutical treatment (OR = 2.81, P = 0.04) and unemployment (OR = 2.72, P = 0.04). Neither restlessness nor impulsivity predicted in-patient suicide. CONCLUSIONS Suicidal ideation, unfavourable clinical course and the use of multiple psychotropic substances (reflecting the severity of illness) were strong determinants of railway suicides. The most salient finding was the vital impact of a change of therapist. These findings deserve integration into the clinical management of patients with serious mental disease.

Work-related posttraumatic stress disorder (PTSD) and other emotional diseases as consequence of traumatic events in public transportation: a systematic review. Int Arch Occup Environ Health 2014; 88:549-64. [PMID: 25267495 DOI: 10.1007/s00420-014-0980-3] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2014] [Accepted: 09/04/2014] [Indexed: 10/24/2022]
Abstract
BACKGROUND Drivers in public transportation are at risk of experiencing potential traumatic events such as accidents involving persons, collisions, or suicides. In this context, the question arises to what extent psychological traumatization and posttraumatic diseases occur. PURPOSE The aim of this systematic review was to describe the frequency and nature of work-related posttraumatic disorders, to analyze risk and prognostic factors after potentially traumatic events (accidents resulting in damage to property and/or in injury or death), and address sick leave after such events in the realm of public transportation, based on the available literature. METHODS Systematic review based on four databases (PubMed, PSYNDEX/MEDLINE, ScienceDirect, PILOTS) between 1980 and June 2013. RESULTS We identified seven studies (four longitudinal, three cross-sectional) that examine employees after person under train (PUT) events. PTSD prevalences varied broadly between 0.7 and 17 %. The same applies to dysthymia/neurotic depression (1-26 %). However, similarly low prevalences of major depression (1.3-2.8 %) and panic disorder (0.5-1.3 %) have been observed. Risk factors of PTSD comprised individual, work-related, event-related, and prognostic aspects. Following the traumatic event, a total of 69-81 % of the drivers were absent, and if sick leave occurs, this was on average 3-19 days. CONCLUSIONS It became evident that drivers in public transportation run a high risk of sick leave. It was also striking that despite the immense impact of PUT and high number of suicides, only an infinitesimal number of studies exists. Due to various differences (period of follow-up, instrument of measurement and study period), it turned out that the comparability of the results of the studies is limited. For various reasons, further research is urgently needed, as from an occupational health point of view the issue of posttraumatic diseases and implications for fitness for service should be addressed.

BMC Public Health 2014; 14:124. [PMID: 24498876 PMCID: PMC3933256 DOI: 10.1186/1471-2458-14-124] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2013] [Accepted: 02/04/2014] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND The majority of fatalities on the European Union (EU) railways are suicides, representing about 60% of all railway fatalities. The aim of this study was to compare time patterns of suicidal behaviour on railway tracks in Germany between two observation periods (1995-1998 and 2005-2008) in order to investigate their stability and value in railway suicide prevention. METHODS Cases were derived from the National Central Registry of person accidents on the German railway network (STABAG). The association of daytime, weekday and month with the mean number of suicides was analysed applying linear regression. Potential differences by observation period were assessed by adding observation period and the respective interaction terms into the linear regression. A 95% confidence interval for the mean number of suicides was computed using the t distribution. RESULTS A total of 7,187 railway suicides were recorded within both periods: 4,102 (57%) in the first period (1995-1998) and 3,085 (43%) in the second (2005-2008). The number of railway suicides was highest on Mondays and Tuesdays in the first period with an average of 3.2 and 3.5 events and of 2.6 events on both days in the second period. In both periods, railway suicides were more common between 6:00 am and noon, and between 6:00 pm and midnight. Seasonality was only prominent in the period 1995-1998. CONCLUSIONS Over the course of two observation periods, the weekday and circadian patterns of railway suicides remained stable. Therefore, these patterns should be an integral part of railway suicide preventive measures, e.g. gatekeeper training courses.

Abstract
BACKGROUND Railway suicide has significant adverse impacts for the victims, their family and friends, witnesses to the incident, general public and train network. There is no previous review on the socio-environmental factors and railway suicide. The research question asked in this review was: 'What socio-environmental risk and protective predictors are significantly associated with railway suicide?' METHODS The review searched Medline, PsycINFO, Web of Science and Scopus for English-language studies that assessed the associations between socio-environmental (i.e. geographical, physical, economic and social) factors and railway suicide from their inception to June 2013. It was reported based on the PRISMA Statement. RESULTS Eleven studies met the inclusion criteria. They were categorised into railway environments (availability of railways and trains, accessibility to railways and familiarity with trains), population characteristics and impact of media reporting. Findings from ecological studies using population level railway suicide data suggested weak and inconsistent evidence for the first two categories. The evidence on the impact of media reporting was moderately strong, with irresponsible media reporting being associated with an increased risk of railway suicide. CONCLUSIONS There is a need for further research activity to strengthen evidence about socio-environmental risk factors for railway suicide. The focus of this research should be on the factors that determine individuals' decisions of using the railway as a method of suicide, with the consideration of a range of geographical, physical, social, and economic factors.

Abstract
PURPOSE Suicide and trespass are major contributors to risk on the railway, resulting in around 170-180 fatalities per year in Lucknow region, as well as associated major disruption to the rail network. Lucknow is the capital city of the state of Uttar Pradesh in India. METHODS The analysis included train-pedestrian fatalities during 2007-2012. The data for 2007-2012 were collected from the autopsy reports of the university, case sheets from the hospital, the general prosecutor's investigations report and the inquest reports from police. RESULTS The results show that the majority of victims were males. Half of the suicide victims were 20-39 years old. Accidents happened most frequently in situations when a person was walking on the tracks/in front of train (22.7%) or were crossing the tracks illegally (20.9%). Among all train-pedestrian fatalities, about half of the victims (42.8%) were intoxicated by alcohol. Female suicide victims suffered from mental health problems more frequently (55.8%) than male suicide victims. CONCLUSION Overall, there is no reason to believe that train-pedestrian fatalities are unavoidable. By contrast, the effective prevention of railway suicides and accidents should be based on a systems approach involving effective measures introduces by several organisations such as government, railway organisations, various authorities (such as public health, education, enforcement, urban planning) and communities. Same measures can often be used to prevent both trespassing and suicides, even though their effectiveness may depend on the target group. In addition, there are measures specifically targeted to prevent either trespassing or suicides.

Abstract
When compared to German rates, train suicides in The Netherlands have made up a larger proportion of the total number of suicides. This study examines whether this difference is attributable to railway parameters, familiarity with rail transport, or population density. Dutch and German train suicide rates from 2000 to 2007 were compared by means of Poisson regression analyses. Train suicide rate ratios were calculated and related to the railway parameters or population density in a Poisson regression model. The Dutch-German general suicide rate ratio was 0.72. In contrast, the train suicide rate in The Netherlands exceeded the German rate by 1.23. In the Poisson regression analyses, where suicide rate was related to railway density or passenger traffic intensity, the Dutch-German train suicide rate ratios became 1.49 and 1.20 respectively. When related to train traffic intensity or population density, however, rate ratios turned into 0.74 and 0.59 respectively. Train traffic intensity contributes to train suicide frequency. Population density also contributes, whereas railway density and familiarity with rail transport do not. In a cross-national comparison the availability hypothesis regarding the number of trains passing was confirmed, which leads to the recommendation of limiting access to the railway tracks.

Abstract
BACKGROUND Railway and metro suicides constitute a major problem in many parts of the world. Japan has experienced an increase in the number of suicides by persons diving in front of an oncoming train in the last several years. Some major railway operators in Japan have begun installing blue light-emitting-diode (LED) lamps on railway platforms and at railway crossings as a method of deterring suicides, which is less costly than installing platform screen doors. However, the effectiveness of the blue lights in this regard has not yet been proven. METHODS This study evaluates the effect of blue lights on the number of suicides at 71 train stations by using panel data between 2000 and 2010 from a railway company in a metropolitan area of Japan. We use a regression model and compare the number of suicides before and after and with and without the intervention by the blue light. We used the number of suicides at 11 stations with the intervention as the treatment group and at the other 60 stations without the intervention as the control group. RESULTS Our regression analysis shows that the introduction of blue lights resulted in a 84% decrease in the number of suicides (CI: 14-97%). LIMITATION The analysis relies on data from a single railroad company and it does not examine the underlying suicide-mitigation mechanism of blue lights. CONCLUSION As blue lights are easier and less expensive to install than platform screen doors, they can be a cost-effective method for suicide prevention.

Abstract
BACKGROUND Following the railway suicide of Robert Enke, a famous German football goal keeper, short-term copycat effects have been found. Main aims of the present study were to analyze long-term effects of this incidence and to compare them with overall national suicide data, as well as to investigate possible "anniversary effects". METHODS For long-term effects, the number of railway suicidal acts in the two years before and after Robert Enke's suicide (10th November 2009) were compared. For anniversary effects, the corresponding 2-week-periods in 2009, 2010 and 2011 were analyzed. Incidence ratios with 95% confidence intervals were computed. RESULTS Compared to the two years before Enke's suicide the incidence ratio of the number of railway suicidal acts in the 2-year-period following this event increased by 18.8% (95% confidence interval (CI)=11.0-27.1%; p<0.001). The median number of suicidal acts per day increased from 2 to 3 (p<0.001). This effect remains significant after excluding short-term 2-week effects of Enke's suicide. An anniversary effect was not present. The increase of fatal railway suicides between 2007 and 2010 (25%) was significantly different from that for the total number of suicides in Germany (6.6%) (p<0.0001). LIMITATIONS Due to missing data, analyses regarding gender were limited and regarding age not feasible. CONCLUSIONS Long-term effects of Enke's suicide on railway suicidal acts in Germany in the sense of copycat behavior are probable as this increase cannot be explained by corresponding changes of the total number of suicides in Germany.

Abstract
The aim of this study was to describe the frequency of fatalities, timing of collisions and characteristics of persons killed in train-pedestrian collisions on Finnish railways during 2005-2009. In addition, the Finnish results were compared with those collected in Sweden. The Finnish data were combined from five different sources. The results showed that 311 pedestrians were killed in train-pedestrian collisions, including 264 suicides, 35 accidents and 12 unclassified events. For each event type, most of the victims were male. Most suicide victims were in the 20-29 year age group and on average younger than people who chose some other form of suicide. About half of all victims were intoxicated by alcohol, medicines and/or drugs. Both suicides and accidents occurred most often at the end of the week but no specific peak for time of year was found. Suicides occurred most frequently from afternoon to night and accidents during the rush hours. Most train-pedestrian fatalities happened in densely populated areas. In conclusion, the effective prevention of railway suicides and accidents calls for a systems approach involving effective measures introduced by authorities responsible for urban planning, railways, education and public health.

Abstract
Background: Belgium is a country with a high suicide rate (19.1/100,000 in 2004), and railway suicide poses a substantial safety and public health problem. This problem was addressed by the Suicide Prevention Unit of Infrabel (Manager of the Belgian Railway Infrastructure), which collects relevant data and implements a prevention program. Aims: To present data on fatal and nonfatal suicidal behavior on the Belgian railway network, including monthly and regional distribution and identification of hotspots; and to present the Infrabel suicide prevention program. Methods: Analysis of Infrabel data on railway suicide (1998–2009) and comparison with data on suicide in Belgium. Results: A total of 1,092 railway suicides (1998–2009) and 557 suicide attempts (2003–2009) in Belgium (fatality rate of 54%) were studied. Monthly fluctuations were observed, with the majority of suicides occurring in Flanders, followed by Wallonia and Brussels. We identified 34 hotspots accounting for 35% of cases, mostly in Flanders. Conclusions: In 2004 railway suicide accounted for 5.3% of all suicides in Belgium (railway suicide rate of 1.03/100,000). Such a major human and economic loss warrants implementation of prevention measures. Infrabel has initiated a comprehensive suicide prevention program which focuses mainly on safeguarding the suicide hotspots.

Abstract
BACKGROUND There has been scant research exploring the relationship between choice of method (means) of self-inflicted death, and broader social or contextual factors. The recent emergence and growth of suicide using carbon monoxide poisoning resulting from burning charcoal in an enclosed space (hereafter, "charcoal burning") was related to an increase in the overall suicide rate in Hong Kong. The growth of this method coincided with changing economic conditions. This paper expands upon previous work to explore possible relationships further. PURPOSE This study aims to discern the role of charcoal burning in overall suicide rate transition during times of both economic recession and expansion, as captured in the unemployment rate of Hong Kong, and to examine whether there was evidence of an effect from means-substitution. METHODS Age and gender specific suicide rates in Hong Kong by suicide methods from 1997 to 2007 were calculated. To model the transition of suicide rate by different methods, Poisson regression analyses were employed. RESULTS Charcoal burning constituted 18.3% of all suicides, 88% of which involved individuals drawn from the middle years (25-59) of life. During both periods of rising and declining unemployment, charcoal burning played an important role in the changing suicide rates, and this effect was most prominent among for those in their middle years. Means-substitution was found among the married women during the period of rate advancement (1997-2003). CONCLUSIONS Compared to others, working-age adults preferentially selected carbon monoxide poisoning from charcoal burning.

Abstract
BACKGROUND Constant high-level numbers of railway suicides indicate that prevention strategies against railway suicides are urgently needed. The main question of the present study was whether pre-crash railway suicide behaviour can be identified, using German Federal Police officers experience with suicidal events in railway related environments. METHODS To collect information on pre-crash railway suicide behaviour, a questionnaire was used and made available on the German Federal Police intranet. A total of 202 subjects (mean age: 41 years, sex: 84.9% male) were included in the analysis. Multivariate logistic regression analyses were performed to predict the prevention of suicide (first model) or demand for counselling (second model) as outcomes. Sex, age, years of service, number of experienced suicides, suicides personally observed, information on suicides obtained from witnesses and finally either counselling/debriefing (first model) or whether officers had prevented a suicide (second model) were used as predictors. RESULTS A considerable proportion of police officers reported behavioural patterns preceding a suicide. Half of them observed the dropping or leaving behind of personal belongings or the avoidance of eye contact, more than a third erratic gesture, mimic or movement. Erratic communication patterns and general confusion were each reported by about one quarter. One fifth indicated the influence of alcohol. Less frequently observed behaviour was aimlessly wandering (14.3%) and out of the ordinary clothing (4%). About one third of all railway suicide victims committed suicide in stations. Of those, 70% had chosen an eminent spot. The multivariate logistic regression model using prevented suicides as the outcome identified the number of suicides experienced, counselling/debriefing and having personally observed a suicide as variables with significant impact. The model using counselling/debriefing as the outcome identified age and having prevented a suicide as variables with a significant association. CONCLUSIONS Our results provide evidence that railway suicides are preceded by identifiable behavioural patterns. This emphasizes the importance of educational efforts, taking into account the knowledge and skills of experienced police officers.

Abstract
BACKGROUND National suicide data are an underestimation of the actual number of suicides but are often assumed to be reliable and useful for scientific research. The aim of this study is to contribute to the discussion of the reliability of suicide mortality data by comparing railway suicides from two data sources. METHODS Data for the railway suicides and the concurrent causes of death of fifteen European countries were collected from the European Detailed Mortality Database and the European Railway Agency (ERA). Suicide rates, odds ratios and confidence intervals were calculated. RESULTS The suicide data from the ERA were significantly higher than the national data for six out of fifteen countries. In three countries, the ERA registered significantly more railway suicides compared to the sum of the national suicides and undetermined deaths. In Italy and France, the ERA statistics recorded significantly more railway related fatalities than the national statistical offices. In total the ERA statistics registered 34% more suicides and 9% more railway fatalities compared with the national statistics. LIMITATIONS The findings of this study concern railway suicides and they cannot be extrapolated to all types of suicides. Further, the national suicide statistics and the ERA data are not perfectly comparable, due to the different categorisations of the causes of death. CONCLUSIONS Based on the data for railway suicides, it seems that the underestimation of suicide rates is significant for some countries, and that the degree of underestimation differs substantially among countries. Caution is needed when comparing national suicide rates. There is a need for standardisation of national death registration procedures at the European level.

van Houwelingen CAJ, Kerkhof AJFM, Beersma DGM. Train suicides in The Netherlands. J Affect Disord 2010; 127:281-6. [PMID: 20580436 DOI: 10.1016/j.jad.2010.06.005] [Citation(s) in RCA: 26] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/26/2010] [Revised: 06/02/2010] [Accepted: 06/02/2010] [Indexed: 11/30/2022]
Abstract
BACKGROUND Little is known about train suicide and factors influencing its prevalence. This study tests the hypotheses that railway density, railway transportation volume, familiarity with railway transportation and population density contribute to train suicide. It also tests the relationship between train suicide and general population suicide and examines the prevalence and the characteristics of high-risk locations and their contribution to the grand total of train suicides. METHODS Trends in train suicides were compared with trends in railway track length, train kilometres, passenger kilometres and national suicide figures over the period 1950-2007. The geographical distribution over the national network over the period 1980-2007 was studied. Data were obtained from The Netherlands Railways, Prorail and Statistics Netherlands. RESULTS 1. The incidence of train suicides is unrelated to railway parameters. 2. Being familiar with railway transportation as a passenger is not a contributory factor. 3. Train suicide rates are unrelated to regional population density. 4. The incidence of train suicides parallels that of general population suicides. 5. Half of the train suicides took place at a limited number of locations, the most important of which were situated within a village or town and were close to a psychiatric hospital. LIMITATIONS Most conclusions are based on correlational relationships between variables. CONCLUSIONS 1. Train suicide trends reflect trends in general population suicides. 2. Increased train transportation does not lead to more train suicides. 3. The prevention of train suicide at high-risk locations (HRLs) in built-up areas and near psychiatric hospitals deserves first priority.

Abstract
BACKGROUND Railway suicide is a serious mortality issue. Most attempters are unmarried psychotic young men under psychiatric care having a high level of lethal intent. Installation of platform screen doors (PSDs) to limit access to the track has been suggested as an effective way for prevention. This study aims to examine the effectiveness of installing PSDs for preventing railway suicides; any sign of substitution of suicide location; and changes in psychiatric profile of suicide deceased after the PSD installation in the subway system of Hong Kong. METHODS Cases of railway suicide and related information from 1997 to 2007 were provided by the railway operators and the Coroner's Court. The effectiveness of installing PSDs was assessed through a quasi-experimental setting. Poisson regression and chi-squared test were used. RESULTS Over the 11-year study period, a total of 76 railway suicide cases (0.71% of all suicides) were reported. A significant reduction of 59.9% (p=0.0003) in railway suicides was found after the PSD installation. Analyses confirmed that there was no significant sign of substitution by displacing potential attempters to unsealed platforms (p=0.9051). Those having psychosis would be better protected as no suicide cases with such psychiatric background were reported after the installation of PSDs. LIMITATIONS It has not considered the potential economic benefits of PSD. It is difficult if not possible to examine whether the potential attempters would substitute to an alternative method of suicide. CONCLUSIONS This study shows that PSDs can effectively prevent suicides with no substitution by "delethalizing" the image and altering people's perception about the desirability of railway suicide. Railway operators should extend the coverage of PSD to all railway stations in Hong Kong without any delay.

Abstract
PROBLEM Subway transit is a relatively safe mode of transportation, yet compared to all other forms of mass transit in the United States (U.S.), subways have the highest fatality rate. The aim of this paper is to characterize subway-related fatalities in order to identify opportunities for risk reduction. METHOD Medical examiner records for all New York City (NYC) subway-related deaths (1990-2003) were reviewed. Data were abstracted on decedents' demographics and autopsy findings, including laboratory findings. RESULTS There were 668 subway-related fatalities, of these, 10 (1.5%) were homicides, 343 (51.3%) were determined to be suicides, and 315 (47.2%) were accidental. Although decedent characteristics varied between fatality categories, they were not particularly informative with regard to prevention. CONCLUSION Prevention strategies that focus on structural controls are likely to be most efficacious in improving the overall safety of the NYC subway systems. IMPACT ON INDUSTRY These findings suggest that structural rather than individual-level interventions would be most successful in preventing subway fatalities.

Baumert J, Erazo N, Ruf E, Ladwig KH. Time trends in suicide mortality vary in choice of methods: an analysis of 145,865 fatal suicide cases in Germany 1991-2002. Soc Psychiatry Psychiatr Epidemiol 2008; 43:913-9. [PMID: 18560783 DOI: 10.1007/s00127-008-0380-7] [Citation(s) in RCA: 22] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/14/2007] [Accepted: 05/16/2008] [Indexed: 02/06/2023]
Abstract
BACKGROUND Overall, decreasing suicide mortality rates were observed in the last decades in most Western populations. However, it remains unclear, whether these favourable trends occurred uniformly in particular suicide methods. Therefore, the present study evaluated time trends of suicide mortality by method in Germany over the period 1991-2002. METHODS A total of 145,865 fatal suicide cases of men and women aged >or=15 years and with available suicide method were recorded by the Federal Statistical Office of Germany (suicides coded "death following a suicide attempt" were excluded). Based on these data, seven different suicide methods were defined. Poisson regression was used to estimate the age-adjusted annual percentage change (AAPC) of the number of each suicide method. RESULTS The most frequently used suicide methods in both sexes were hanging, strangling or suffocation (HSS) with 55.8% in men and 39.9% in women, followed by self-poisoning. Statistically significant declines of the number of suicides were observed, in descending order, for self-poisoning, drowning and HSS in both sexes. In contrast, methods using firearm discharges or stab with a sharp object remained in roughly constant level. Modifications of time trends were observed for several methods by age classes. CONCLUSIONS The present study demonstrates different time trends for suicide methods. Further examinations are recommended in particular concerning possible reasons for the choice of a suicidal method.

Abstract
The aim of the present study was to review international literature on the incidence of suicide on railway networks, describe risk factors associated with it, and examine existing prevention practices. Searches on Medline and PsycINFO for the period 1966-2007 were performed. Thirty original studies published in English on epidemiology of rail suicide were included in the review along with peer-reviewed articles on risk factors and prevention of rail suicide. Internationally, suicide by collision with a train accounted for 1-12% of all suicides, with up to 94% of all attempts resulting in death. Suicide by train seriously affects not only survivors, but also train drivers and bystanders. Correlations between density of rail network, number of passengers and number of suicides by train have been found. Conflicting data exist on gender ratio of this type of suicide, but studies are homogenous in identifying young adults (20-40 year of age) as those most exposed to train suicide. Documented psychiatric diagnoses were found in up to 83% of cases. Mid-seasonal peaks were also identified, with events occurring mostly during late morning and early afternoon. Limited evidence exists for effective suicide prevention practices. Successful examples are represented by pits and sliding door systems (Singapore Mass Rapid Transit System) and responsible media reporting (Viennese Subway). Suicide by train involves emotional and financial costs to individuals and society as a whole. A combination of different strategies might significantly reduce its effect.

Abstract
OBJECTIVE A study on the incidence of suicide in the train system and a description of main characteristics of victims and attempters was commissioned by Queensland Rail in response to an apparent increase of suicide phenomena and their consequences. METHODS Two sources of data were used for the analyses: the Queensland Suicide Register (QSR) and the Queensland Rail Incident Surveillance Information System (ISIS). Data on suicide were cross-checked on the two systems for the years 1990-2004. ISIS provided information on cases of attempted suicide for the period 1993-2206. RESULTS One hundred and sixty-one train suicide victims were identified. Globally, they represented 2% of all cases of suicide in Queensland. During the examined period no significant changes in trends of suicide through that method were found. Of all suicide cases, 59 (36.6%) included victims aged 15-24 years. The ratio of male :female was 4:1, equal to the sex distribution of suicide with all methods in Queensland. Positive blood alcohol content was found in nearly 50% of young people and in 29.8% of the total sample. A psychiatric diagnosis was documented in 40.4% of all train suicide victims. Only 18 suicide attempters were identified through the ISIS database; of them, 15 were male and three were female, with a gender ratio similar to that of suicide victims. CONCLUSIONS This study involved the largest dataset ever published in Australia on this topic. In Queensland, train suicides presented a stable trend during 1990-2004. Subjects of very young age (15-24) seem to be particularly exposed to this method; in this age group one in two individuals had positive blood alcohol content.

Abstract
Abstract. This article reviews research on railway and metro (underground and subway) suicides around the world. Although the incidence and survival rates vary and standardized methodologies are lacking, it is evident that there is a high incidence among psychiatric patients and at stations, crossings, and track areas near psychiatric institutions. Fictional and news reports of railway and metro suicides are related to increased rates, and false beliefs about a certain, fatal, and painless outcome may contribute to use of this method. Train drivers and rail personnel are often traumatized and in need of personal support after the incident. Most prevention involves surveillance, limiting access to tracks, or prompt intervention during an attempt. Other potential strategies include focusing upon the high-risk populations of previous attempters and patients in psychiatric facilities near stations and tracks and changing attitudes concerning the acceptability of this method to ensure that potentially suicidally active individuals are not under the illusion that this is a certain and painless method of death.
