Fence and restrict trackside access at identified black-spots

The proposal

Use incident data to map recurring trackside hotspots (bridges, open track near footpaths, level crossings) and harden them with lineside fencing, mid-track fencing, vegetation/lighting changes and access restriction. Implemented by infrastructure managers (e.g. SBB's "black-spot" programme).

Why it would work

A large minority of rail suicides happen away from platforms; in Austria, 15 hotspots on 0.9% of track length accounted for up to 17% of railway suicides. Concentrated fencing removes access precisely where deaths cluster, at far lower cost than network-wide barriers.

Evidence

Swedish mid-track fencing cut suicides at treated stations by ~62.5%. Hotspot analysis is well established in Austria and Switzerland. Effectiveness is location-specific and displacement risk is real: one Swedish study saw a 62.5% local drop coincide with a ~162% rise at control stations on the same line.

A nationwide English study found deaths widely dispersed (median 2.1 miles from home, no strong clustering), implying hotspot-only strategies can miss most cases.

Implementation path

Rank sites by incident density and feasibility; fence and restrict access; monitor treated and neighbouring sites for displacement.

Trade-offs and limitations

Best combined with network-wide measures. Assumes suicides concentrate at identifiable hotspots, which does not hold universally.
