Casualties at train stations TW

Trigger warning.

I am so saddened and baffled by how often lines seem to be shut down because people fall or jump.

It seems to happen multiple times a month.

I feel awful for anyone who has to witness this. Then the chaos caused by the trains needing to be delayed or cancelled can cause serious over crowding on platforms which is so dangerous.

At what point can anything more be done? Can more be done? Should we have barriers at the platforms? Can the gaps be reduced?

I just really don’t understand, and I appreciate that is naive.
