Look dude... The train reference is an example... We know there was no train...  The example given is to let you understand that if you ever decide to take your life it's really selfish of you to do so in a way that inconvenience and traumatize other people...  Like not parking your car and creating a traffic mess or jumping on the train rails...  These women deserved to be tossed too though. Telling him to jump just because of their inconvenience is another level of assholery.
