I think another feature we should have on tsw would be to have on board passenger announcements "the next station is etc..." And we could have platform announcements too as trains pull in or when a train is delayed it'll announce it on the platform I think this would be really awesome to add into the wcml!
They want to make it a core feature. When they will do that is another question. Rivet has already done this on their most recent routes.
I hope they could do this in a future update it'll be pretty cool to have that in game it'll just make the game feel really immersive!
