LMS 6P Royal Scot Class 4-6-0 No 6131 'The Royal Warwickshire Regiment' is seen standing at New Street station. Built by the North British Locomotive Company in September 1927, No 6131 was renumbered as No 46131 by British Railways in August 1948 which it carried until November 1962 when it was withdrawn from 6G Llandudno shed to be scrapped. The parallel-boilered Royal Scot Class were rebuilt when their boilers and cylinders were life-expired as they suffered a number of design faults including smokeboxes which were difficult to keep airtight. Between 1943 and 1955 the whole class was rebuilt. The rebuild was quite substantial, requiring new boiler, frames and cylinders but in most cases the original frame stretchers, wheels, cab and fittings were retained. The usual procedure carried out was that as each locomotive arrived for rebuilding, it was stripped and the identity transferred to a fresh frameset prepared using the parts recovered from the locomotive that had previously been re-built. The new frames were slightly shorter than the originals. Thus, most rebuilt examples retained their own cab, wheels etc., but most of the frame stretchers, and other integral parts of the frame were from the previously re-built locomotive.
