The Coaling Plant, also known as the Coal Mine is a coaling plant and mine, located northeast of Wellsworth. The plant also has a diesel refueling station.

The Coaling Plant first appeared in the fifth season and made regular appearances until the show switched to full CGI. It has been mentioned, however, in the Island of Sodor openings and in several Mr. Perkins segments.

Locations in the Coaling Plant

The Truck Hoist

One of the machines at the Coaling Plant is the truck hoist. This machine has a platform, which trucks full of coal are placed onto the platform, lifted up and then tipped over to empty the coal. It is dangerous for engines to go on it. However, Henry accidentally pushed Percy onto the Truck Hoist and Toby was pushed by Diesel onto the truck hoist when the steam and Diesel engines were fighting each other. Later, Percy used it again but to hide from Thomas.

The Mine

In the fifth season, the coaling plant had a mine. A train of trucks got stuck on a mechanism at the mine shaft's entrance. Percy gave them an extra hard shunt to get them moving, but pushed them too hard. The trucks came off the rails, crashing into a support beam. This caused the mine to collapse, destroying the trucks. Percy evacuated the mine and saved himself with a canvas barrier he remembered from earlier. The mine's last appearance was in A Surprise for Percy.

Learning Segments


  • The coaling plant caused some issues with Christopher Awdry, as originally there was no coal mine on Sodor and all the coal was imported from the mainland.
    • However, starting from the eighteenth season onwards, coal once again is imported from the mainland in the television series.
  • The fifth season version of the plant reuses some buildings from TUGS, as well as part of the Skarloey Railway Engine Sheds set.
