Plot
Thomas is bored with his job of shunting coaches and complains to the other engines about it. One night, Edward offers Thomas to swap jobs with each other. Edward would shunt coaches, while Thomas took his trucks. With this, Thomas happily agrees.

Unfortunately, When Thomas takes Edward's trucks, he did not know how troublesome the trucks could be and loses control of them. The trucks push him down a hill and Thomas slips into a siding, where some buffers prevent a nasty accident. The Fat Controller arrives and advises Thomas that he should learn more about trucks if he is to become a Really Useful Engine.
