The London, Tilbury and Southend Railway 1 class was a class of 4-4-2T suburban tank engines. Thirty-six were built between 1880–1892, by Sharp, Stewart and Company and Nasmyth, Wilson and Company. They were the first locomotives owned by the LTSR, as previously all train services had been run by the Great Eastern Railway (GER) under contract.
They were ostensibly designed by Thomas Whitelegg and were the first 4-4-2T locomotives to operate in Britain. However, documentation exists to suggest that the design was actually by William Adams, then working for the GER. A member of this class was recorded as having hauled a train of 240t at an average of 82.2 km/h to Southend with water taken during runs.
On the LTSR they were numbered 1–36 and named for places on or near their railway line. In 1912, the LTSR was absorbed by the Midland Railway and the locomotives were renumbered 2110–2145 and the names removed. At the grouping in 1923, all passed to the London, Midland and Scottish Railway and at first retained their former MR numbers. However between 1923 and 1927 twenty-five were progressively renumbered—2110–2119 to 2200–2209 in 1923, 2120–2124 to 2210–2214 in 1925, and 2125–2134 to 2190–2199. In 1930, all 36 were renumbered in the 2056–2091 range.
Retirements started in 1929, and by 1936, all had been withdrawn. None were preserved.
