The Diesel Squad is a group of Diesels that come from Diesel City
The Diesel Squad formed when Dash-9 moved from Canada to Cartoon World. Then they built their own Dieselworks in Diesel City. They enjoy being devious, but will help if they have to. They often do tricks to the rest of Stuingtion's engines. But once, Dash-9 joined the Decepticons only to be defeated. But then they encounter Thomas and Twilight Sparkle a few more times later.
