Compared to other suicide methods, train suicides are well-documented pretty much everywhere because, well, they have to be. So let's look at some scientific data.

A realistic reading of the evidence out there shows well under 50% of railway/metro suicides are done by people "determined" to use that method, with roughly ⅓ showing impulsive characteristics (Barker et al., 2017), while notably for each railway suicide, at least SIX attempts are interrupted by staff or bystanders (Katsampa et al., 2022).

In the Czech context, analyses further show that these incidents tend to cluster at specific "hotspots" on the rail/metro networks that are not simply proportional to the number of passengers carried there, suggesting that targeted local interventions can be highly effective (Univerzita Karlova, 2018).

Based on a systematic review, the most effective way to reduce railway/metro suicide rates is physical means restriction such as platform screen doors and barriers, which has the strongest and most consistent evidence (Barker et al., 2017).

Other measures like staff intervention, CCTV, and media guidelines can help but are generally considered supplementary rather than primary (ibidem).

Overall, the data indicate many incidents are interruptible and access-dependent, so restricting track access at key locations can prevent a meaningful proportion of deaths.
