Crovan Gate's Steamworks (also known as Sodor Steamworks or The Railway Works) is a large repair company that specialises in fixing steam The Steamworks is accessible and used by the steam engines on both the North Western and Skarloey Railways. All of the essential components for steam locomotives are kept and made here. Heavy overhauls are also carried out here. Jim, Victor and Kevin both live and work here at the Sodor Steamworks.
In 1915 the North Western Railway established its repair shops at Crovan's Gate. Since 1925 these shops have been expanded as required till, with the decline of steam on the Mainland, the Works are now equipped with machinery and craftsmen able to tackle any type of steam locomotive overhaul or rebuilding that may be needed. Sir Topham Hatt has been looking into the possibility of manufacturing parts for engines on heritage railways.
The Works Diesel, Jim, is known to work here, and according to Donald, other diesels also live here.Following Shane Dooiney's return from Switzerland in 1963, the Fat Controller saw to it that the Culdee Fell engines could be repaired here, ensuring expensive journeys overseas for the Culdee Fell locomotives are no longer necessary. In 1976, Jock's firebox, boiler and cylinders were fabricated here; the rest of him was built at Arlesburgh Works. In 1996, Ivo Hugh was built here by the Skarloey Railway's Engineering Department.
In 2009, Sir Topham Hatt IV gave the Repair Works a complete revonation to the works and renamed it 'Crovan Gate's Steamworks'. He hired Victor and Kevin to work there.
- Hanseler is the only known engine to have been made on Sodor in 1958. The others are undocumented, although Jock's firebox, boiler and cylinders were fabricated here in 1976; the rest of him was built at Arlesburgh Works.
