Based on the story of the same name from Tank Engine Thomas Again.

Thomas meets Terence the Tractor, and says his wheels are ugly. Terence explains that they're caterpillar tracks, and he can go "anywhere". This comes in handy during the winter when Thomas doesn't use his snowplough and gets stuck in a snowdrift.

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

Gordon, James, and Henry are upset that they have more work to do. Now that Thomas is gone, they have to shunt their own coaches. Because of always having to turn around to shunt, Gordon and James have trouble on the turntable. Gordon has to pull his train backwards, while James spins around like a top.
