The GER Class G69 was a class of twenty 2-4-2T steam locomotives built by for the Great Eastern Railway by S. D. Holden in 1911–12 following the design of two rebuilt examples of the GER Class M15 designed by James Holden, his father, in 1904. They all passed to the London and North Eastern Railway at the 1923 grouping and received the classification F6.

History

These locomotives were fitted with 17 1⁄2-by-24-inch (444 mm × 610 mm) cylinders and 5-foot-4-inch (1.626 m) wheels. They were the final development of the GER's radial (2-4-2T) tank locomotive. Being intended for London suburba service, they were built with condensing gear, and Westinghouse air brakes.[1]

All were still in service at the 1923 grouping, the LNER adding 7000 to the numbers of nearly all the ex-Great Eastern locomotives, including the Class G69 locomotives. The LNER added vacuum ejectors to all but one locomotive in 1927; the one exception being fitted in 1929. They also removed the condensing apparatus between 1936 and 1938.

On 1 January 1923 the whole class was allocated to Stratford Engine Shed and were employed on suburban traffic in East London on the lines out of Fenchurch Street and Liverpool Street.[3]

789 and 790

Two of the GER M15 rebuilds, numbers 789 and 790, were given Class G69 cabs. This resulted in them being incorrectly classified, which affected their route availability. When the GER was amalgamated into the LNER in 1923 they were classified F6 (instead of F5). It wasn't until 22nd December 1948 that the "twins", now numbered 67218 and 7219 respectively, were correctly reclassified into the F5 category. 7219 received her British Railways number in November 1949 after a general repair at Stratford.

British Railways

At Nationalisation in 1948, British Railways added 60000 to their LNER numbers. They all continued in service until 1955, when the first was withdrawn; all were gone by May 1958 and none survived into preservation. [1]

New-build Project

As none of the F4s, F5s or F6s were preserved, The Holden F5 Steam Locomotive Trust is recreating GER number 789 from the beginning. As of March 2018 the frame plates, cylinder blocks, motion bracket, star stay, and buffer beams have been cast and are awaiting assembly at Tyseley Locomotive Works. Work on the frames' assembly is subject to the Trust successfully negotiating a lease for the relocation of the completed job.

When completed, 789 is set to appear as the original locomotive did when rebuilt in 1912. Features include the high-arched G69-style cab, Ramsbottom safety valves, condensing gear, and the smaller (6/6.5 inch) Westinghouse air brake pump.
