I know there is the Shuttle Train mod, and you can carry a loco in your pocket for when you need one, but it would be quite neat to just walk to a train line, get on it, select a destination and -be- the train, automatic pilot mode, with the game treating you like a locomotive, obeying signals and using the (crazy) in game pathing.
I had a glimpse inside a mod that added something to power armor, and I was engulfed in an OOP maze that left my head spinning.
Thanks in advance for any modder who takes this on board.
