I tried coupling Class 150/153/170 together. They coupled successfully but they can't move. Anyone know what I can do? More info - I tried coupling a Class 150 and Class 153, tried opening doors at both Class 150 and Class 153 end using hotkeys, and both guard panels, and the front (Class 153)'s doors opened. Also, despite closing all doors and setting up the cabs with the correct safety devices, the train just does not move, brakes are on 0.0 but just refuses to move.
Likely just the way they were set up. Which is odd, because they can and do couple together in reality.
Turn the AWS on and then you'll be able to take power. I'm not sure if the 170 is the same but the 150/153 won't move without the AWS on.
