London & North Western Railway
About
The London and North Western Railway (LNWR) was a British pre-grouping railway formed on 16 July 1846 by the amalgamation of the Grand Junction, Liverpool & Manchester, London & Birmingham and Manchester & Birmingham railways. It was for many decades the largest joint-stock company in Britain and ran the West Coast Main Line between Euston and Carlisle, with an extensive network in the West Midlands, Lancashire and North Wales. The company styled itself the 'Premier Line' on the strength of its London–Crewe–Carlisle trunk and its share of the Anglo-Scottish boat-train traffic.
Locomotive engineering was concentrated at Crewe Works (founded 1840) and at Wolverton Works (carriages). Successive Locomotive Superintendents and Chief Mechanical Engineers, Francis Trevithick, John Ramsbottom (1862–1871), Francis Webb (1871–1903), George Whale (1903–1909), Charles Bowen Cooke (1909–1920) and H. P. M. Beames (1920–1922), built up a fleet that at its peak numbered 3,300 locomotives, the largest of any British railway.
The Webb era is associated with British compound expansion, eight successive compound classes between 1882 and 1903, and produced both technical successes (the 'Coal Tank', the 'DX Goods', the 'Cauliflower' 0-6-0) and famous failures. Whale's reaction was to build large numbers of straightforward simple-expansion engines, particularly the 'Precursor' 4-4-0 and 'Experiment' 4-6-0 of 1904–1905; Bowen Cooke followed with the George the Fifth superheated 4-4-0 and the four-cylinder Claughton 4-6-0.
The LNWR amalgamated with the Lancashire & Yorkshire Railway on 1 January 1922 in anticipation of the Grouping, and the combined company became part of the LMS one year later on 1 January 1923. Crewe Works continued as the LMS's principal locomotive works and remains today (under Alstom ownership) on the same site.
