One Good Turn

One Good Turn is the nineteenth episode of the third season.

Plot
Bill and Ben are sent to work in the yard, and as a reward for their hard work they are allowed to have a go on the turntable. Unfortunately, Bill is sent onto the same line as Ben and they end up buffer to buffer. Both blames each other for the incident, and they decide to give each other the silent treatment. Eventually, Edward and BoCo, at the end of their tether, ask the Fat Controller to intervene. The Fat Controller decides to give them BoCo's heavy goods train, and Ben claims to be able to pull it himself. When he discovers the train is too heavy for him, the twins realize their mistake and work together to pull the train.
