I’m not sure if it’s a great idea but what happens if you can play as a signal maintainer in game mode when you don’t want to drive a locomotive or being a conductor in the train. It will be awesome for people like myself who works in the signal department to learn hands on experience what is like to be a signal maintainer and what they do
It would way too complex, I think, I mean it could maybe work with simple signal boxes, but with full ROC's, it ain't gonna happen.
