Diesel 10 (Wooden)
He's biggest bully on the railway.
He's scheming against Steamies. One time in Thomas and the Magic Railway, he was chasing Thomas and Lady. The viaduct was collapsing. Thomas jumped the gap after Lady made it, and Diesel 10 fell into the gap. He couldn't hold onto the track with his claw and fell into a barge of sludge!
Percy is Thomas' best friend.
He pulls the mail car.
He's one of the Scottish twins.
He's No. 10. He's from Scotland.
