Crovan's Gate Works, usually known as the Works, the Foundry, or the Fitter's Yard, are where the railway engines and rolling stock are serviced and repaired. In the Railway Series, the Works are situated at Crovan's Gate, opposite the Skarloey Railway.
There was also a repair yard at the Shunting Yards.
However, with the introduction of the Sodor Steamworks, it is unknown what became of the former site of the Railway Works. Since rolling stock has been seen outside it throughout the CGI series, it is probably now a carriage and wagon shed.
- According to the 1958 Railway Series map of Sodor , "Engines are made and repaired at Crovan's Gate". However, no known engines are documented as having been built there.
