Scruff

Scruff is a small tank engine from The Island of Sodor.

Personality
Scruff is a grubby little chap, who runs on steam but has a square diesel like body. He loves getting dirty as he shunts rubbish trucks ready for "scrunching" and he is good friends with Whiff, Irving and Warrior. In fact in his earlier days he has been known to run away from having to get clean. Like a tiny ant, Scruff can be seen carrying his tiny self around busily working in the background. He keeps up a cheerful demeanour to other engines and doesn't give much thought to what people think of him or how messy he can get sometimes.

Basis
Scruff is based on No. 9369 "Musketeer", a Sentinel 100 HP BE Type chain-driven vertical-boiler steam locomotive built in 1946 by Sentinel Waggon Works. "Musketeer" is preserved by the Northamptonshire Ironstone Railway Trust.

Livery
Scruff is painted lime green with dark green stripes, funnel and front. He has brass nameplates on either side of his tanks, although his name is only written on these in merchandise. In the television series, the plates are completely blank.

 * Scruff travels far faster in the television series than his basis is capable of.
