History
[edit]These locomotives were a development of the GER Class E72, and shared the same 20-by-28-inch (508 mm × 711 mm) cylinders, 4-foot-11-inch (1.499 m) wheels, and Belpaire firebox-fitted boiler. Changes included vacuum brakes from new, and the abandonment of cylinder tail rods.

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 T77 locomotives. Between 1934 and 1939 all were rebuilt with round-top fireboxes, and the cylinder bore was reduced to 19 inches (483 mm).[1] The rebuilt locomotives were reclassified J19/2, while the yet-to-be rebuilt locomotives reclassified J19/1. The J19/2 classification also included the rebuilt former Class E72 locomotives.[2]
At nationalisation in 1948, British Railways added 60000 to their LNER numbers. They all continued in service until 1959, when the first was withdrawn; all were gone by the end of 1962.[1]
