Thomas and Friends

Down the Mine (1x25)

:

Thomas teases Gordon about the time he fell in a ditch, much to the horror of Annie and Clarabel. Thomas doesn't care a bit, and is then sent to work at the Mines. He notices a danger board that says "Danger, Engines Must Not Pass This Board" near the tracks, goes past it to prove there's no danger, and ends up falling down the mine instead of going past it.
