LMS Rebuilt Patriot Class

The London Midland and Scottish Railway (LMS), Rebuilt Patriot Class was a class of 4-6-0 steam locomotives. They were rebuilt from LMS Patriot Class locomotives (which were the fourth type of LMS 2A boilered 4-6-0 locomotives) over the period 1946–1949. By the end of 1947, the LMS had rebuilt seven engines, these being 5514/21/26/29–31/40. After nationalisation, a further eleven locomotives were rebuilt. Rebuilt locomotives retained their numbers.^[1]

Rebuilding

Between 1946 and 1949 eighteen LMS Patriot Class engines were rebuilt with Stanier 2A boiler, cab and tender, though these were largely paper rebuilds, based on the LMS Rebuilt Royal Scot Class. Seven (Nos 5514/21/6/9-31/40) had been rebuilt by the start of 1948 when British Railways inherited them. In March 1948 BR added 40000 to their numbers to number them 45514/21/6/9-31/40. Subsequently, BR rebuilt another 11 of the Patriots, so that the rebuilt engines were (4)5512/14/21–23/25–32/34–36/45. The two original members of the class, and the first ten of the nominal rebuilds, were not rebuilt due to their non-standard parts.
