The Vicarstown Dieselworks is a repair yard that specialises in diesel engines. It is the diesel equivalent of the Sodor Steamworks. The Dieselworks is located in a quarry-like area, not far from Vicarstown. When it was first introduced, the Dieselworks was run down and shabby, with insufficient and damaged equipment. After a fire broke out in the main building, it was rebuilt. DenDart and Diesel 10 live and work at the Dieselworks, with the former two acting as head diesels.

The company's logo is a picture of a diesel engine, of similar appearance to Den's class. Both Den and Dart have this logo on their liveries.

In the nineteenth series, the small warehouse, that serves as an extension to the main Dieselworks building, is shown to house a large smelting foundry, where all the broken parts are melted down and reused again, to build new parts.

In the twenty-third series, the diesels got trapped in the sheds during a busy period and remained trapped the next morning. The fact that Diesel, Paxton and Sidney were seen working afterwards confirms that all the diesels who were trapped were freed.

According to a magazine article, Dennis also lives at the Dieselworks.


Non-Rail Vehicles


Equipment at the Dieselworks includes:



  • A scrapped model of Charlie's cab is seen inside.
  • A scrapped Märklin Engine has been seen at the Dieselworks in Blue Mountain Mystery as a reference to all the scrap engines by Greg Tiernan.
  • Unlike the Sodor Steamworks there is no Skarloey Railway access to it meaning there is no way Rusty (and to an extent, any narrow-gauge diesels) can get repaired unless taken by flatbed.
    • However, it may be possible that narrow-gauge diesels are repaired by the Steamworks instead.
