I think that if we had the ability to choose whether to be driver or guard would be good the role could include opening and closing doors checking/giving tickets or even the role of train dispatcher but we would need a better timetable for that to be fun as there would be a lot of standing around
That would be a great feature to add the game and this can give the players a choice to drive or collect tickets, open/close doors, click the guard or conductor buzzer, and ability to chat with passenger collecting ticket
I often thought this in Train Sim, with British routes, CD / RA would be a nice touch as well as guard dispatch. I would love to see these within TSW.
