Vicarstown is a small town on the eastern side of Sodor. The North Western Railway built their terminus and headquarters here in 1915, but after a 1925 agreement with the LMS Railway to allow NWR trains to stop in Barrow-in-Furness there was no further use required. A smaller replacement station was built for the engines operating the car ferry service, and the turntable was relocated at Barrow and the headquarters moved to the other end of the main line at Tidmouth.
In the television series, Vicarstown Sheds are a roundhouse with a turntable at the front and five berths for the engines. The Vicarstown Goods Depot, Sodor Dieselworks, Vicarstown Bridge and a Viaduct are also located here.
It has appeared in the Railway Series books Thomas the Tank Engine, Gordon the High-Speed Engine and Thomas and the Fat Controller's Engines. In the TV series Vicarstown has been mentioned semi-regularly since the seventeenth season. It finally appeared in the television series for the first time in The Great Race, where the station is situated on a viaduct. There appears to be a tramway running along the roads underneath the railway. A cathedral is also located in the town, near the station.
- In The Railway Series, Thomas worked at this station as a pilot engine before working on his branch line (alternatively, Thomas worked as a pilot at Knapford in the television series).
- The name comes from the Reverend W. Awdry's time as an Anglican priest, and on maps of Sodor it replaces the real Vickerstown, a suburb of Barrow situated on the Isle of Walney.
- In The Great Race, many of the houses and or buildings seem to be duplicated.
