I seem to have broken the TUBE! I was doodling around in stonebridge Park Depot and London road, and whenever I would turn off the reverser interlock and flip it into reverse to try to go backwards the train wouldn’t budge. Then I tried turning the reverser interlock back on again and going forwards and the train has become immovable. I tried resetting the train but to no avail:/ Additionally I found that you cannot uncouple trains on Koln aachen, I tried every way I could find and no dice.
