The GER Class G58 (LNER Class J17) was a class of 0-6-0 steam tender locomotives designed by James Holden for the Great Eastern Railway. The class consisted partly of new locomotives built 1905–1911 and partly of rebuilds of the earlier GER Class F48, originally built 1900–1903. The rebuilding started under GER auspicies from 1921 and was continued by the London and North Eastern Railway (LNER) after grouping in 1923.
The earlier GER Class F48 were built between 1900 and 1903 and had round-top boilers; there were sixty of them. The G58 had Belpaire fireboxes, like those fitted to the F48 No. 1189, and later fitted to the Class D56 Claud Hamilton 4-4-0s. A further thirty of the Belpaire boiler type followed to form Class G58.
The class was superheated between 1915 and 1932. From 1921, all the round-top boilers were replaced by the Belpaire type and the majority were of the superheated type.
All the J16s had been rebuilt as J17s by 1932 and 89 J17s passed to British Railways (BR) in 1948. BR numbers were 65500–65589, of which 65500–59 were the rebuilds from F48 (J16). One number (65550) was blank, because locomotive no. 8200 had been destroyed in a German V-2 rocket explosion at Stratford in November 1944. The second locomotive was withdrawn in 1953, and the last in 1962.
