The London, Midland and Scottish Railway had the largest stock of steam locomotives of any of the 'Big Four' Grouping, i.e. pre-Nationalisation railway companies in the UK. Despite early troubles arising from factions within the new company, the LMS went on to build some very successful designs; many lasted until the end of steam traction on British Railways in 1968. For an explanation of numbering and classification, see British Rail locomotive and multiple unit numbering and classification.
George Hughes was an English locomotive engineer, and chief mechanical engineer (CME) of the Lancashire and Yorkshire Railway (L&YR) and the London, Midland and Scottish Railway (LMS).
Francis William Webb was an English railway engineer, responsible for the design and manufacture of locomotives for the London and North Western Railway (LNWR). Webb was born in Tixall Rectory, near Stafford, the second son of William Webb, Rector of Tixall.
George Whale was an English locomotive engineer who was born in Bocking, Essex, and educated in Lewisham, London. He worked for the London and North Western Railway (LNWR).
Hewitt Pearson Montague Beames was Chief Mechanical Engineer of the London and North Western Railway from 1920 to 1922.
John Ramsbottom was an English mechanical engineer. Born in Todmorden, then on the county border of Yorkshire and Lancashire. He was the Chief Mechanical Engineer for the London and North Western Railway for 14 years. He created many inventions for railways but his main legacy is the split metal piston ring, virtually all reciprocating engines continue to use these today.
Locomotives of the London and North Western Railway. The London and North Western Railway (LNWR) Locomotive Department was headquartered at Crewe from 1862. The Crewe Works had been built in 1840–43 by the Grand Junction Railway (GJR).
William Barton Wright was an English mechanical engineer, also tea plantation owner and mine owner. He was Locomotive Superintendent of the Lancashire and Yorkshire Railway (LYR) from 1875. During his ten-year career in that post he helped to make the LYR one of the most efficient railways in the United Kingdom, by designing a range of good locomotives to haul the LYR's traffic.
The Lancashire and Yorkshire Railway Class 5 were 2-4-2T steam locomotives designed by Chief Mechanical Engineer (CME) John Aspinall and introduced from 1889 for local passenger work. Later batches included progressive modifications such as extended coal bunkers and Belpaire fireboxes. The final batch built from 1911 to 1914 under George Hughes incorporating superheated boilers gave increased tractive effort, others were also rebuilt to this standard. When Hughes introduced his classification system in 1919, the more powerful superheated locomotives were designated Class 6. The final examples were withdrawn in 1961.
The L&YR Class 21 is a class of small 0-4-0ST steam locomotive built by the Lancashire and Yorkshire Railway for shunting duties. They were nicknamed Pugs.
The London and North Western Railway (LNWR) Improved Precedent Class or Renewed Precedent Class is a class of 2-4-0 steam locomotives originally designed for express passenger work. They later gained the nickname of Jumbos.
The Lancashire and Yorkshire Railway (L&YR) Class 8 was a four-cylinder 4-6-0 express passenger locomotive designed by George Hughes introduced in 1908.
The London and North Western Railway (LNWR) "Precursor" Class was a type of 4-4-0 ("American") steam locomotive designed by the company's Chief Mechanical Engineer, George Whale. Introduced in 1904, it should not be confused with the LNWR 2-4-0 "Precursor" Class of 1874 designed by Francis Webb, the last example of which was scrapped in 1895. In 1906, a 4-4-2T ("Atlantic") tank variant of Webb's engine, the "Precursor Tank" Class, also entered service.
The London and North Western Railway (LNWR) 4ft Shunter was a class of 0-4-0ST steam locomotives. Introduced in 1863 by Ramsbottom, 26 were built in 1863–1865, 10 in 1870, 10 in 1872, and 10 in 1892. The last three of the latter batch were soon rebuilt as 0-4-2ST crane tanks. They survived into LMS ownership in 1923 and the last one was withdrawn in 1933.
The L&YR Class 2 (Aspinall) was a class of 4-4-0 steam locomotives of the Lancashire and Yorkshire Railway.
The London and North Western Railway (LNWR) DX Goods class was a class of 0-6-0 steam locomotive, designed by John Ramsbottom for freight duties. 943 were constructed, making them the largest single class of steam locomotives built in the United Kingdom. Despite this, none were preserved.
The London and North Western Railway (LNWR) 7 ft 6 in Single 2-2-2 class was a type of express passenger locomotive designed by John Ramsbottom. The class is better known as the Problem class for the first locomotive built, or the Lady of the Lake class for the example that was displayed at the International Exhibition of 1862.
The London and North Western Railway (LNWR) Precursor class was a class of forty 2-4-0 steam locomotives designed by F. W. Webb and built at the railway's Crewe Works between 1874 and 1879.
The LNWR 18-inch Goods was a class of 310 0-6-0 freight steam locomotives built by the London and North Western Railway at their Crewe Works between 1880 and 1902.
The LNWR Samson Class was a class of ninety 2-4-0 steam locomotives built by the London and North Western Railway at their Crewe Works between 1863 and 1879.
