Terrible situation to be in, but have another thought for the poor train driver and various people who literally have to pick up the pieces. What's wrong with a bag of tablets, bottle and bed, less people traumatised. Sorry but its selfish. Even better get some help, talk to the right people, things can be rock bottom but there is surely always a route back. God bless him anyway.
I appreciate the train driver will probably be very badly affected by this, but what you say is very much of a simplification. It is very easy for a rational & intelligent outsider to say this, but poor old Enke was not in a rational state.
When you feel such dispair you are looking for the quickest and most effective way of ending it all and you do not think that anyone can help. I know there is a route back, but in mid August I didn't and, if it was not for a couple of very twinkle toed Glasgow policemen I would not be able to type this.
You are right in that there is a route back and very good people to help - I am a living example - but it is very difficult for someone who has not been there to understand just how hopeless & helpless you can feel.
It will be very difficult for Enke's friends & family, but I hope they can understand that there was never anything personal in the action of poor Enke.
I hope he is at peace now.
