The Diesel Shunter

This diesel appeared in the third illustration of Not the Ticket, pushing Thomas onto a lorry when he was being taken to the National Railway Museum in York.
The diesel is pained in BR black and 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.
