Glitch when you have a train depot right in front/behind of a station

It's my first time playing, ok? I decided to put a train depot at the end of my line, which is at a station. So, I placed my depot right next to the station, made sure it was connected, then I spawned a train, but it wouldn't move anywhere. It didn't even visibly spawn in. I think I may have screwed myself over, because I can't demolish the building because of the train that won't go back into the depot.

Haha, nevermind, I figured out it was a signal or something stopping it. I forced it go ahead of the signal, and it started moving.
