The London, Midland and Scottish Railway (LMS) Rebuilt Royal Scot Class is a class of 4-6-0 steam locomotives. 70 members of this class were rebuilt by the LMS and its successor British Railways (BR) from LMS Royal Scot Class engines by the replacement of their life expired parallel boilers with a type 2A boiler over the period 1943–1955. (The class sometimes is numbered 71 as it included a prototype 1935 rebuild LMS (4)6170 British Legion, but sufficient technical differences existed which dictate that it is treated separately). They were the second class to be rebuilt with type-2 boilers, after the rebuilding of British Legion and the Jubilee Class.

LMS gave them the power classification 6P; this was later revised by BR to 7P.

46154 The Hussar during the 1948 exchange trails with an ex-WD tender.

In the 1948 Locomotive Exchange Trials, carried out by the recently nationalised British Railways, involved 46154 The Hussar and 46162 Queens Westminster Rifleman. Apparently a rebuilt 'Royal Scot' proved capable of matching the maximum performance of the much larger LMS Coronation Class. [2]
