Trains change the way we behave. People on a bus are quite different to people on a train. On a bus a conversation is more likely than a train. Even the way people wait at stations or on the train is different. Everyone seems a bit stiffer, less malleable. Like the difference between a metal wheel and a rubber tyre.
Maybe it’s because it’s so much more mechanical than a bus. Well, it feels it anyway. On a bus you can at least know that it’s been driven by a human. On a train, who knows? And on fully automated trains it’s even more mechanical and strange.
The waiting itself is less of an unknown on a normal day. Timings are all measured and presented. It is waiting on track.
