History

These locomotives had 20-by-28-inch (508 mm × 711 mm) inside cylinders driving 4-foot-11-inch (1.499 m) wheels. They had a distinctive front overhang, not possessed by any other GER 0-6-0 class. This was needed to clear the cylinder tail rods.[1] Locomotive 1240 was fitted for a time with a Weir feedwater heater and pump, with the heater component mounted on the boiler between the dome and chimney.[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 E72 locomotives. Between 1935 and 1936, the LNER rebuilt them in line with its standards, and reclassified them as class J19/2, the same as the rebuilt GER Class T77 (which had been LNER class J19, later J19/1, before rebuilding).

At nationalisation in 1948, British Railways added 60000 to their LNER numbers. They all continued in service until 1958, when the first was withdrawn; all were gone by the end of 1961.[2]
