History
In 1888, Holden experimented by removing the side rods of T19 No. 721 to form a 2-2-2.[1] In 1889 the first of a new class appeared: initially No. 740 (later 789 and 780) which had been built on a 'Locomotive and Machinery' account. This was followed by two batches of ten on the more normal 'Letter' account.[2] in 1893. They were built with Script error: No such module "convert".[3] inside cylinders powered by a Script error: No such module "convert". boiler. They were later rebuilt with Script error: No such module "convert". and Script error: No such module "convert". boilers.[2]

One of their main spheres was on the Joint Line working expresses to York. In 1896 the class inaugurated the epic making non-stop run to North Walsham using oil-firing. Rous-Martin[4] found that the singles climbed Brentwood Bank more rapidly than the 2-4-0s. See also Ahrons (1951).
Nine locomotives were withdrawn between 1901 and 1903. The surviving eight locomotives in the 770-series were transferred to the duplicate list in July 1904, and had their number prefixed with a "0". The remaining fourteen were withdrawn between 1904 and 1907.[5]
