I wanted to drive the Class 142, but the doors couldn't open. Then I tried to get into the class 142, and I opened the doors, but it didn't work, and I sat in the driver's seat, and then I realised that the reverser is stuck on neutral. Can't believe I found another bug.
You were under the train when it spawned, that's probably why. Try standing on the platform when spawning the train and it should work.
