P class of 1893–94. Also in 1864, John Lambie of the Caledonian Railway built twelve Class 1 4-4-0T locomotives. Inside cylinder tender locomotives Between 1876 and 1903, Samuel Johnson of the Midland Railway built 350 inside cylinder tender locomotives to various designs, notably the Midland Railway 483 Class. The type was particularly refined by John F. McIntosh of the Caledonian Railway with his Dunalastair and Breadalbane classes of 1896 to 1898. In addition, Wilson Worsdell of the North Eastern Railway designed six classes between 1896 and 1909. Other notable classes included the London & South Western Railway’s T9 class of 1899 and the London & North Western Railway’s Precursor Class of 1904. From the mid-1890s until after World War I, the inside cylinder 4-4-0 was the standard type for British Express passenger trains, although several classes were also used in mixed-traffic service in later years. The Great Western Railway (GWR) preferred to retain outside frames on their inside cylinder 4-4-0s. One member of its City class, the City of Truro, designed by George Jackson Churchward and built at the GWR's Swindon Works in 1903, was reputedly the first steam locomotive in Europe to travel in excess of , reaching a speed of on 9 May 1904 while hauling the Ocean Mails special from Plymouth to London Paddington. Although the inside cylinder 4-4-0 had largely been superseded by larger locomotives for mainline express trains by 1920, the type remained in use in Scotland and East Anglia, where lines that could not support heavier or larger locomotives were common. Thus both the Great Eastern Railway’s Claud Hamilton classes of 1900 to 1911 and the Great Central Railway’s Director classes of 1920 were perpetuated by the London & North Eastern Railway in 1923. Until 1932, the London, Midland & Scottish Railway also continued to build its Class 2P of traditional inside cylinder for secondary passenger working. Three-cylinder tender locomotives Experiments were conducted with three-cylinder compound locomotives by Wilson Worsdell of the North Eastern Railway in 1898, Samuel Johnson of the Midland Railway in 1901 and Francis Webb of the London & North Western Railway. Of these, the development of Johnson's design by Richard Deeley of the Midland Railway into the 1000 Class was the most successful. This class continued to be built by the London Midland & Scottish Railway (LMS) after 1905, until 1932 with the almost identical LMS Compound 4-4-0. British three-cylinder
