List of Thomas & Friends film characters

Thomas and the Magic Railroad is the only Thomas & Friends movie released in theatres.

• Diesel 10 (or simply Diesel) (voiced by Neil Crone in Thomas and the Magic Railroad and Matt Wilkinson in the CGI series) is an evil diesel engine with an excavator claw arm (which he calls "Pinchy") extending from his roof. He is Diesel's brother and the main antagonist in Thomas and the Magic Railroad. Thomas said that he is rated "10 out of 10 for devious deeds and brutal strength". Diesel 10 reappeared in the 2005 direct-to-DVD followup Calling All Engines!, and is the main antagonist in Day of the Diesels. He is based on a British Rail Class 42.
• Lady (voiced by the series creator Britt Allcroft) is a small, Victorian-styled tank engine who has magical powers and also appeared in Calling All Engines!. In the Calling All Engines! DVD's character gallery, Lady is described as "a magical engine. When she moves along the rails, she spreads gold dust with her special powers. Lady has been known to help Thomas and his friends when there was no other engine to turn to." It is not believed she is based on any particular engine, and she is likely an original design.
• Splatter (voiced by Neil Crone) and Dodge (voiced by Kevin Frank) (collectively called "Splodge" by Diesel 10) are Diesel 10's sidekicks. Like Diesel, 'Arry and Bert, Splatter and Dodge are based on a British Rail Class 08, and were modified from the models of 'Arry and Bert with new faces.[1]
