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 London, Tilbury and Southend Railway and were the first 4-4-2T locomotives to operate in Britain.
