The GER Class D27 was a class of 2-2-2 steam tender locomotives designed by James Holden for the Great Eastern Railway.
History In 1888, Holden experimented by removing the side rods of T19 No. 721 to form a 2-2-2. 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. in 1893. They were built with inside cylinders powered by a boiler. They were later rebuilt with and boilers.
