PS4 [resolved] 350 Won't Move

I figured this would be the best place to ask, since google wouldn't help. I'm on the carriage collector scenario, I've moved onto the 350, and I'm in the shunting siding, but the train won't move. Brakes are off, pan is up, master key is not on in the other carriage. So, if anyone has any ideas on how to fix the problem, please do tell me.
