    Dennis the Lazy Diesel 
 * Number: 11001

Dennis is a lazy diesel. He was built at Ashford Works, England, in 1949.

Bio
Dennis was lazy and kept making excuses to get help with his goods. While Thomas got another engine to take Dennis' trucks, Dennis ran away but derailed and ran into some bushes. When Thomas discovered Dennis' folly he helped him onto the rails. Dennis learnt his lesson, and is presumably still working hard.

Persona
Dennis is clever but lazy, and uses his cleverness to make excuses to get help with his workload, like pretending to not know the way to his destination and pretending to be over-heated so another engine will do his work. But, Dennis always gets into trouble when he's caught out telling lies, but now he is really useful and hard-working in future.

Basis
Dennis is based on a type of Bulleid diesel, "No. 11001".

Livery
Dennis is painted gray with dark gray bonnet and gearbox. He carries the number 11001, like his prototype.

Appearances
Dennis first appeared in the ninth season episode "Thomas' Day Off". He made a cameo in a learning segment also. He also made a cameo in "The Great Discovery". Dennis made a cameo in Thomas and the Valentine's day surprise.
