The GER Class D27 was a class of 2-2-2 steam tender locomotives designed by James Holden for the Great Eastern Railway.

In 1888 Holden experimented by removing the side rods of T19 No. 721 to form a 2-2-2.[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.[3] in 1893. They were built with Vorlage:Convert[4] inside cylinders powered by a Vorlage:Convert boiler. They were later rebuilt with Vorlage:Convert and Vorlage:Convert boilers.[3]

Table of orders and numbers[3]

1889 LM68 Stratford Works 1 740 Renumbered 789, then 780
1891 D27 Stratford Works 10 770–779
1893 F32 Stratford Works 10 1000–1009

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[5] 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Nine locomotives were withdrawn between 1901 and 1903.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 The remaining fourteen were withdrawn between 1904 and 1907.[6]
