Diesel is a devious BR Class 08 diesel shunter who works on the North Western Railway.
Diesel is, in essence, the average pantomime villain. He is oily, malicious, devious, scheming, and full of ideas to get revenge. It appears Diesel has a good side in him, but one would still have to look deep to find it. He does want to be a really useful engine, however, since his arrival, he has given Diesels a bad reputation. He is also very proud to be the first diesel on Sodor.
Diesel is based on a BR Class 08. Over seventy members of this class survive today in preservation, while around 100 remain in service on the national rail network. They were in fact the most successful shunting engines in the world, with 996 of them built.
Diesel is painted in the British Railways' black livery. His livery originates from British Railways in the 1950s, during the time when all shunting engines were painted black.
