Western is a BR Class 52.
He is painted in BR green with D999 on his sides and the BR logo.
He is based on BR Class 52 'Western' Diesels built for the Western region of British Railways. He has the nickname of the class and no extra added.
Because he plays a minor role in the film, his personality is not seen. However, he is shown to be a sarcastic, netrual engine. He shows no hatred or like to Percy and Kevin. He is good friends with Hymek, but his sarcasticness sometimes gets out of hand, but he claims he does it 'to entertain'.
- Western's number is an in-joke. The Class 52 numbers started at D1000.
