Biography

Sir William Arthur Stanier (1876–1965) was a British locomotive engineer who, after a distinguished thirty-six-year career on the Great Western Railway, was recruited to take charge of the London, Midland and Scottish Railway in 1932. The classes he produced over the next decade, the Princess Royal and Princess Coronation Pacifics, the Black Five mixed-traffic 4-6-0, the Jubilee and the heavy 8F freight 2-8-0, formed the backbone of the LMS fleet at nationalisation and survived in BR service to the end of steam.

Stanier was born at Swindon on 27 May 1876, the son of an assistant to William Dean, and apprenticed at Swindon Works in 1892. He rose through the Churchward and Collett eras to become Principal Assistant to Collett in 1922 and was for a time the heir-presumptive to the GWR top job. The LMS Board, frustrated with Fowler's small-engine policy and convinced that the company needed Swindon discipline, recruited him in January 1932.

Stanier brought the GWR's tapered Belpaire boilers, top-feed and standardised parts to Crewe and Derby. The Princess Royal Pacific (1933) gave way in 1937 to the streamlined Princess Coronation, of which No. 6220 'Coronation' attained 114 mph the same year and 'Coronation Scot' worked Britain's only pre-war Anglo-Scottish high-speed train. The 842-strong Black Five and 852-strong 8F became the most numerous LMS classes and worked across the network.

From 1942 he served as Scientific Adviser to the Ministry of Production, in which capacity he became one of only two locomotive engineers (with Gresley) to be elected a Fellow of the Royal Society. He was knighted in 1943. He retired formally in 1944, was succeeded by Charles Fairburn and then by George Ivatt, and died at Rickmansworth on 27 September 1965.

Locomotives designed

LMS 2 — Likely reference to Fowler's LMS 2-6-4T or LMS Class 2 4-4-0 — see specific class entries.
LMS 8F war — Wartime production of Stanier's LMS 8F class 2-8-0 — adopted by the War Department in 1940 as the standard British military 2-8-0. Over 700 built between 1940 and 1946 by various contractors for British and overseas military use. Many returned to British service postwar; LMS/LM(S)R class 8F. Several preserved including 8233, 8431, 48624, 48773, 48305 etc.
LMS Jubilee Class — Sir William Stanier's three-cylinder express 4-6-0, the LMS's principal express engine on routes that could not accept the heavier Pacifics. One hundred and ninety-one engines were built between 1934 and 1936 across Crewe, Derby, and the North British Locomotive Company. The class was named to mark King George V's Silver Jubilee of 1935; engines were named after British colonies and dominions, naval ships, places, and dignitaries. Four are preserved, Bahamas, Kolhapur, Leander, and Galatea, three of which are main-line registered.
LMS Princess Coronation — Sir William Stanier's four-cylinder Pacific designed for the LMS's Coronation Scot service of 1937, the most powerful express passenger steam locomotive ever built in Britain. Thirty-eight engines were constructed at Crewe Works between 1937 and 1948, the first batch in streamlined "torpedo" casing for the Anglo-Scottish high-speed service, later batches and the post-war engines unstreamlined. The class set a British steam speed record of 114 mph (1937) and worked the West Coast main-line top-link expresses through to early-1960s replacement by Type 4 diesels. Three are preserved.
LMS Princess Royal — Sir William Stanier's first Pacific design for the LMS, a four-cylinder express 4-6-2 produced in 1933 to take over the heaviest West Coast main-line expresses from the Royal Scot 4-6-0s. Thirteen engines were built at Crewe Works in 1933–1935, including the unique turbine-driven prototype No. 6202. The class introduced large taper-boiler Pacific practice to the LMS and provided the engineering foundation for Stanier's later Princess Coronation. Two are preserved.
LMS Stanier 8F — Sir William Stanier's heavy freight 2-8-0, the LMS's standard heavy goods engine and a major British wartime military export. Eight hundred and fifty-two engines were built between 1935 and 1946 by Crewe, Horwich, the Vulcan Foundry, the North British Locomotive Company, Beyer Peacock, and (under wartime government direction) the LNER's Doncaster, the GWR's Swindon, and the Southern's Brighton and Eastleigh Works. Many were sent overseas during World War II for military service, particularly in Persia, Egypt, and Italy. Seven are preserved.
LMS Stanier Black Five — Sir William Stanier's two-cylinder mixed-traffic 4-6-0, the most numerous and arguably the most successful steam class ever to run in Britain. Eight hundred and forty-two engines were built between 1934 and 1951 across Crewe, Horwich, Derby, Vulcan Foundry, and Armstrong Whitworth, with the final batches outshopped under British Railways. The class had universal LMS and BR route availability, hauled almost every kind of train from Glasgow to Bournemouth, and worked through to the very end of British steam in August 1968. Eighteen are preserved.
LMS Turbomotive — Stanier's 1935 LMS 6202 "Turbomotive" — a unique LMS Princess Royal class 4-6-2 fitted with a Ljungström steam turbine instead of cylinders. Worked LMS expresses 1935–1949 with mixed success; rebuilt as conventional Princess Royal No. 46202 "Princess Anne" in 1952, but destroyed in the Harrow & Wealdstone disaster of 8 October 1952 only weeks after entering service. Not preserved.
