Trains can get stuck in a depot "waiting for free path" under the following conditions: A train is going to a depot that is included in its order list but is interrupted by a "send to depot" command which sends it the depot it was going to anyway. When the train is released, the original order to go the depot is still active. In most cases the train will exit, circle around and reenter the depot it just left. But in others, the train is stuck waiting for a free path, because it wants to exit and reenter the same depot and can't find a path. A stuck train can be freed by skipping the current go to depot order or by telling it to ignore the signal.

Attached is an example. Train 80 was on its way to the depot when it was issued a send to depot command. It is now "stuck" in the depot.
