The Sodor China Clay Company (abbreviated as SCC) is a company based at Brendam, which is responsible for the supply and transportation of china clay to Brendam Docks.

The Company operates a private railway which runs from Brendam Docks to the china clay workings, which consist of a quarry, which is known as the Clay Pits, and a mine, which is known as the Clay Mines.

History and Operations

The Railway Series

The clay beds were discovered in 1948, and the Company was formed to work them. A new harbour, capable of accommodating ocean-going vessels, was built in Brendam, some one and a half miles south of the old one, and a private railway laid down to link the Workings with the harbour and the North Western Railway. The clay is used in making porcelain, paper, paint, plastics, medicines and cosmetics. It is shipped from Brendam all over the world.

Nowadays, the majority of Brendam's 4,500 inhabitants are employed in one way or another by the Clay Company. Spoil, consisting of quartz and sand, from the pits has been dumped in heaps some two miles to the northwest of Brendam and have been dubbed "white mountains".

Thomas & Friends

In the third series, the Clay Pits were struck with a large avalanche. Luckily, Bill and Ben were able to help evacuate the Clay Pits before anyone was injured. It made regular appearances until Bill and Ben were relocated to Ffarquhar Quarry in the sixth series and later the Sodor Slate Quarry that same series.

It was mentioned in the seventeenth series episode, Gone Fishing, that Bill and Ben work at the Clay Pits once again. In Tale of the Brave, when the Clay Pits returned in CGI with Timothy accompanying Bill and Ben. Marion also works here. There were two large landslides that occurred at the Clay Pits, Bill and Ben rescued Thomas from one and another was triggered a while after, which involved Percy saving James.

Two sheds are located at the Clay Pits, one for Bill, Ben and Timothy and another for Marion.
