Thomas & Friends S01E16 - Trouble in the Shed

Based on the story of the same name from Troublesome Engines.

The big engines go on strike, so the Fat Controller asks Edward to work in the yard again. But Edward can't manage alone and is bullied by the bigger engines, so the Fat Controller buys a new engine called Percy and shuts the big engines up in the sheds. In the end, Thomas and Edward run the main line while Percy runs the branch line with Annie and Clarabel.
