The Diseasel

"We're sorry mister, er..." "Never mind. Call me BoCo!"

- the twins and BoCo

The Diseasel is the twenty-first episode of the second season. In the US it first aired on the Shining Time Station episode Double Trouble.

Plot
Bill and Ben leave some china clay trucks to collect some more, but return to find them gone. Their crews deduce that the thief is a diesel, and the two go to find the diesel. They soon find him in the yard, and to pay him out confound him into thinking there is one engine capable of teleporting onto different lines, until Edward shows up and explains. The twins apologise to the diesel, who calls himself BoCo, and leave Edward and BoCo to make humour of the situation.
