Troublesome Trucks are trucks that cause trouble on the Island of Sodor. They have some cargo or coal and sometimes stone inside of them. They try to trick the engines into doing stuff like sorting them into the wrong areas or pushing on. ScRuffy was a troublesome truck that leaded the trucks to singing annoying songs until Oliver broke him. Trucks are always troublesome and are untrusteble even if you ask them to derail you they take it overboard.
