I'm sorry, but this is kind of bullshit. I really do get suffering and the need to CTB, but doing it via train is so selfish and irresponsible. I used to have to commute for hours to see my ex-girlfriend, and then back to get to school. We had a couple people suicide via train and there were many of us that missed important exams or emergencies because somebody decided to jump in front of a train. I am one of the most understanding people when it comes to the need to end it on your own terms on your own time, but this isn't it at all.
Let's not even get into if somebody manages to see, gets PTSD and winds up on this forum. It's not a joke, and the people condoning this kind of behavior should think about others wellbeing as well. I know that's hard when a lot of us are in irredeemable, terrible miserable situations, but there ARE good people out there that can be hurt by our actions, and just because we won't be around to see it doesn't mean they won't have to live with that for the rest of their lives. There are other methods that don't have to involve others and pass on that suffering to them.
Sorry for being harsh, I really do feel for you, and I'm sorry, but it needs to be said.
