Locomotives of the LMS : Fowler Royal Scot class : 6100 Royal Scot

Until the mid-1920s, the LMS had followed the Midland Railway's small engine policy, which meant that it had no locomotives of sufficient power for its expresses on the West Coast Main Line. These trains were entrusted to pairs of LMS/MR Midland Compound 4-4-0s between Glasgow and Carnforth, and a 4-6-0 locomotive of the LNWR Claughton Class, piloted by an LNWR George V 4-4-0, southwards to Euston station .
The Operating and Motive Power Departments of the LMS were satisfied with the small engine policy. However, in 1926 the Chief Mechanical Engineer, Henry Fowler, began the design of a compound Pacific express locomotive. The management of the LMS, faced with disagreement between the CME and the other departments, obtained a loan of a GWR Castle class locomotive, Launceston Castle, which was operated for one month between Euston and Carlisle.
Following the success of the Castle 4-6-0 in working on the LMS, a decision was taken to cancel Fowler's Pacific project, and to replace it with a 4-6-0 with three cylinders and a simple-expansion steam circuit. Because there was an urgent need for new express locomotives the LMS placed an order with the North British Locomotive Company of Glasgow for 50 engines. The North British, with its extensive drawing office and two works, possessed sufficient capacity to expedite the order within a year. The Derby drawing office and North British staff collaborated in designing the class, with the latter producing the working drawings. Fowler took little part in the design process, which was carried out by Herbert Chambers, Chief Draughtsman at Derby, and his staff. The LMS requested a set of drawings of the Castle class from the GWR, but didn't receive them. Instead a set of drawings of the SR Lord Nelson Class were obtained, and used for the design of the firebox. The main features of the design followed existing Derby practice, with the cylinders and valve gear being derived from the Fowler 2-6-4T, also being designed at Derby at that time.
They were introduced without testing. Radford claims that the boiler owed much to the MR 0-10-0 Lickey Banker 'Big Bertha'. A further 20 were built by Derby Works.
They were initially named after regiments of the British Army, and after historical LNWR locomotives. Those with LNWR names were renamed in 1935 and 1936 with more names of regiments.
From late 1931, after several bizarre forms of smoke deflectors were tried on various locomotives to stop drifting smoke obscuring the crew's forward vision, the straight sided smoke deflectors were added. These were later replaced by deflectors with angled top. From 1933 the class was taken off the top-link expresses, being superseded by the LMS Princess Royal Class and later the LMS Princess Coronation Class pacifics.

In 1933 the LMS was invited to send a locomotive and train to the Century of Progress International Exposition in Chicago, USA. It was decided to send an engine of the Royal Scot class, and one was selected that was due for general overhaul. The identity of this locomotive is generally regarded as having been No. 6152 "The Kings Dragoon Guardsman". The coupled axleboxes were replaced with larger ones, based on a GWR design, and the bogie replaced by a De Glehn type, also derived from GWR practice. Springs and spring rigging were also updated, and the boiler replaced. 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
