#suicide-means-restriction

Open, unfenced access to the track edge at stations and along the line makes rail an immediately available, highly lethal suicide method — dangerous especially during short-lived impulsive crises, which account for roughly a third of attempts.

Install blue LED lighting on platforms as a low-cost, easily retrofitted calming/deterrent measure aimed at reducing suicides — an approach with large but heavily contested effect estimates that should not be treated as equivalent to physical barriers.

Construct recessed 'suicide pits' in the trackbed below platform level, giving a person on the track survivable space beneath a passing train. Reduces fatality of attempts without deterring them — a lethality-mitigation complement to other prevention measures.

Systematically identify recurring trackside black-spots and install fencing, mid-track barriers, and access restrictions at those locations — accepting a documented risk of displacement to nearby unfenced sites.

Install half-height automatic platform gates (1.2–1.5 m) where full-height screen doors are too costly or structurally infeasible, reducing platform suicides substantially—though less than full-height, since the barriers can be climbed.

Blue LED lights were installed at platform ends across Japanese stations. Before-and-after panel data studies (14 treated stations, neighbouring and control stations, 2000–2013) reported large decreases in suicides and…

Drainage pits recessed into the trackbed beneath London Underground platforms give a person on the track survivable space beneath a passing train. Where present, they roughly halved the fatality of attempts — but by des…

Mid-track fencing at a Swedish hotspot station reduced suicides at the treated location by 62.5%, but control stations on the same rail line saw a 162% increase over the same period — the clearest documented case of geo…
