That's fair. To my defense, this discussion would look different if I didn't have to reply 50 times that actually no, you can't open windows in trains and no, you can't just get out. It's easy to lose track of all the replies when most of them are nonsense from people that never saw a modern train. I don't think I "got pissy" about your comments regarding cars. They sounded reasonable, just off-topic.
Rewinding to the very beginning, what here doesn't make sense? Many train tracks are fenced and not close to any infrastructure. It can be very difficult to move people to a bus because of it. It's pretty much impossible to put people on another train (because trains can't overtake other trains). You pretty much have to fix the issue before the train can leave which can take many hours. With a car/bus you're right next to the road, you can be easily towed or replacement bus can be sent. At least that's the reality where I live.
