> In high risk stations you can put walls and gates in that only open when a train can be boarded.
That is only possible with fully standardized train units. Which is why you will see this in subways and dedicated high speed networks, but not on the common rail net. Platforms on a larger railway station have to accommodate a range of trains, from metro services (many doors at shorter intervals), to intercity trains (fewer doors, longer carriages), to special trains like night trains (a bunch of carriages from different ages strung together) and rented locomotives with spare carriages to fill gaps in the roster caused by late delivery of new trains.
> Making sure the rails are not accessible with fences around them.
There will always be spots where the rails are somewhat accessible outside of built-up areas.
Besides, all of that is fighting symptoms. Spend the same money on prevention and you'll have much more impact.
Makes sense why I've not seen gates in many places but metro networks and high speed.
I agree that there will always be spots where the rails can be reached. As with many parts of human behavior, if there is more friction less people will do the thing. Since there are many instances where this is a temporary state and seeking and finding help can always be difficult I think creating that frictions is also worthwhile. Making sure people are prevented from feeling suicidal and being happier is something I also fully support.
