The London, Midland and Scottish Railway (LMS) Royal Scot Class is a class of 4-6-0 express passenger locomotive introduced in 1927. Originally having parallel boilers, all members were later rebuilt with tapered type 2A boilers, and were in effect two classes.

London, Midland and Scottish Railway (LMS) Rebuilt Royal Scot Class 6100 (British Railways' number 46100) Royal Scot is a preserved British steam locomotive. The locomotive previously carried the identity 6152 King's Dragoon Guardsman prior to an identity swap with 6100.

The rebuilt locomotive assumed the identity of 6100 The Royal Scot with (on its return from the USA) an enlarged nameplate with details of its appearance at the exhibition. It retained this identity after its return from the USA.

London Midland and Scottish Railway (LMS) Royal Scot Class 6100 (British Railways' number 46100) Royal Scot (formerly 6152 King's Dragoon Guardsman prior to identity swap) is a preserved British steam locomotive. The original 6100 was the first of its class, built in 1927 by the North British Locomotive Company in Glasgow.

The "Royal Scots" continued to be a mainstay of the LMS fleet, right up until nationalisation; the Stanier "Princesses" were a more powerful locomotive but there were never enough of these built to do away with the "Royal Scot" class. The rebuilds of the class were completed by 1953, with the scrapping of the class completed by 1965.

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 locomotives mainly hauled the “Royal Scot” from London to Glasgow and Edinburgh, after which the class was named. They were able to pull the 15 coaches without assistance at an average speed of around 53 mph (85 km/h) and thus achieved very acceptable fuel consumption.

Protecting for the long term, steam locomotives capable of hauling passenger trains on both the main line and on heritage railways. The Royal Scot Trust aims to preserve and maintain steam locomotives for the enjoyment and education of the general public.

Built in 1927, ‘Royal Scot’ was the flagship locomotive of the London, Midland and Scottish (LMS) Railway Company. She was the first in a new breed of steam locomotives capable of hauling heavy trains over the steep gradients found on the West Coast Route.
