Rail suicide

Rail suicide is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Rail suicide rather than just read about it. In short: Rail suicide, or suicide by train is deliberate self-harm resulting in death by means of impact from a moving rail vehicle. The suicide occurs when an approaching train hits a suicidal pedestrian jumping onto, lying down on, or walking or standing on the tracks.

Key takeaways

  • Rail suicide belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Rail suicide to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Rail suicide from memory before moving on to harder problems.

Reference excerpt

Rail suicide, or suicide by train is deliberate self-harm resulting in death by means of impact from a moving rail vehicle. The suicide occurs when an approaching train hits a suicidal pedestrian jumping onto, lying down on, or walking or standing on the tracks. Low friction on the tracks usually makes it impossible for the train to stop quickly enough. On urban mass transit rail systems that use a high-voltage electrified third rail, the suicide may also touch or be otherwise drawn into contact with it, adding electrocution to the cause of death. Unlike other methods, rail suicide often directly affects the general public. Trains must be temporarily rerouted and diverted to clean the tracks and investigate the incident, causing delays for passengers and crews that may extend far beyond the site, a costly economic inconvenience. Train drivers in particular, effectively forced into being accomplices to the suicide they witness, often suffer post-traumatic stress disorder that adversely affects their personal lives and careers. In recent years railways and their unions have been offering more support to afflicted drivers. Research into the demographics of rail suicide has shown that most are male and have diagnosed mental illness, to a greater extent than suicides in general. The correlation of rail suicide and mental illness has led to some sites along rail lines near mental hospitals becoming rail suicide hotspots; some researchers have recommended that no such facilities be located within walking distance of stations. Within the developed world, the Netherlands and Germany have high rates of rail suicide while the U.S. and Canada have the lowest rates. While suicides on urban mass transit usually take place at stations, on conventional rail systems they are generally split almost evenly between stations, level crossings and the open stretches of track between them. Prevention efforts have generally focused on suicide in general, on the grounds that not much can be done at tracks themselves, since suicidal individuals are believed to be determined enough to overcome most efforts to keep them from the tracks. Rail-specific means of prevention have included platform screen doors, which has been highly successful at reducing suicide on some urban mass transit systems, calming lights and ambient music, and putting signs with suicide hotline numbers at sites likely to be used. Some rail networks have also trained their staff to watch, either in person or remotely, for behavioural indicators of a possible suicide attempt and intervene before it happens. Media organisations have also been advised to be circumspect in reporting some details of a rail suicide in order to avoid copycat suicides, such as those that happened after German football goalkeeper Robert Enke took his own life on the tracks in 2009, a suicide widely covered in European media.

History The first recorded train suicide occurred in 1852 in England, where rail development in Europe had been most advanced. In 1879 an Italian researcher noted that railway suicides were most common in Italy's northern Piedmont region, where the rail network was at its most extensive. This led the sociologist Émile Durkheim to reason in his 1897 work Suicide that "the more the land is covered with railroads, the more general becomes the habit of seeking death by throwing one's self under a train," a proposition which has since been generally accepted as a rule. Japan's earliest documented rail suicide occurred in 1876, less than four years after the opening of the country's first railway line. The following month, the Yomiuri Shimbun newspaper reported a second suicide, cautioning its readers that "these days, a strange new way of dying has begun."

Methods Rail suicides typically assume one of three postures: "jumpers" who jump in front of a train from a station platform, "liers" lying on the tracks as one approaches, and "walkers" who wander onto the tracks before the trains are present, a division first identified by researchers on the New York City Subway in 1972, who found jumping the most common and deadliest in their sample. A fourth group included "touchers," all of whom were women, who often went on the tracks after trains had left and deliberately touched the electrified third rail. A German researcher also found some outlying methods like jumping from a moving train and jumping from a bridge into the path of an approaching train. A railway suicide can also be committed by a vehicle driver, such as the Ufton Nervet rail crash, which killed seven others on the train. In addition to individual suicides, joint suicides on railways have also been reported. Studies have found the preferred method differs by country. A 2005 Swedish study found walkers most predominant among 145 suicides, followed by those who sat or lay on the tracks with jumpers third, while a 2008 Australian study of 161 suicides along the Queensland rail network found sitters/liers most common with jumpers and walkers evenly split. German researchers in 2011, looking at over a thousand cases over five years, found the proportions nearly equal, with jumping the least likely to be fatal; twelve years later another group of Germans found liers the largest share, with jumpers close behind. A 2013 U.S. study of 50 suicides where this information was available found a slight edge for liers, with walkers and jumpers evenly split. Electrocution via third rails remains rare; it most often happens in conjunction with suicides on subways or metros, where the body comes in contact with the third rail as it is run over by the train. German researchers believe walkers are most likely to have planned their suicides in advance, while jumpers do it on impulse.

Difference to trespasser accident A collision with a suicidal pedestrian is different from a collision with an unauthorised person, a trespasser, who has illegally entered the tracks, and can be distinguished, according to the European Union Agency for Railways, by the presence of suicidal intent. Ovenstone criteria are mentioned for categorizing a suicidal intent.

Worked examples

Example 1 — a first encounter with Rail suicide

Start with the simplest possible case. Write down what Rail suicide claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Rail suicide before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Rail suicide ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Rail suicide

In research
Rail suicide appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Rail suicide in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Rail suicide is common in secondary-school and first-year university syllabi. It links to neighbouring topics Occupational hazards, Suicide by train, so understanding it makes those chapters shorter.
In everyday life
Look for Rail suicide outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
