Thomas & Friends S01E23 - Dirty Objects

Based on the story of the same name from Toby the Tram Engine.

Toby and Henrietta are still new to the railway, and they often get teased by James about their old-fashioned appearance. However, James gets pushed by some trucks and crashes into some tar wagons, spoiling his own paintwork. Toby and Percy are the only engines who can help and delight in teasing him.
