yeah, I just bet those greedy lying fat cats in charge of First Capital Connect are prepared to fund extra time for trainee drivers to be taught how to handle the stress of actually being forced to kill someone. 
Not sure there is anything that can prepare someone for that, tbh. And even if there was, I'd be amazed if the shysters who run the privatized rail companies would fund it up front. (Although I suppose they may fund something after the fact.)
Some drivers can never do the job again after a jumper. They lose their mental health and their livelihood.
As for 'ooh, it's so nasty making a fuss about a delayed journey when someone has died' - it may sound trivial to you, but commuting is incredibly stressful in the first place. A serious problem that causes chaotic delays and cancellations can be almost unbearably stressful. Especially if you NEED to be back on time to pick up your child and are panicking about how many ruddy hours late you are going to be. Or are on your way to work and worried about how late you are going to be, how the hell you are going to get all your work done, and how on earth you are going to manage to leave on time to pick up your child.
I had a particularly nightmarish journey last Friday, where it was absolute chaos and at one point was stood at a station, watching the departure board going crazy with a long list of cancellations that kept changing, an announcer who was struggling to tell us what was going on, contradicting what the recorded announcements and departure boards were saying. We were all trapped in a massive crowd, boiling hot, and that was just on the platforms - once the train finally pulled in we were jammed into each other's body crevices, boiling hot and the train kept stopping in the middle of nowwhere, with the poor driver saying 'I'm trying to contact the signaller but having no luck so far'.
Worst thing was it was my childminder's daughter's first Brownie promise ceremony. I had specifically arranged to leave work early to make sure I was on time to pick ds up come hell or high water. So my stress levels were off the scale - the thought that my childminder might miss something so important to her dd was terrible. The lack of control and lack of information make it 100 times worse. And traveling in those conditions makes you feel ill - seriously close to fainting.
I do understand that suicidal people are mentally ill and far too consumed by their own pain to give much thought to the consequences of their actions on others. But the impact other people can be catastrophic (drivers, train crew, the poor sods who have to clear up) or extremely physically, mentally and emotionally stressful (the passengers).
P.S. Despite leaving work 30 minutes early, I was late. Making my childminder late for the ceremony. Thank heavens one of the other families whose child was making her first promise was also delayed, so Brown Owl held on.
