Lunghai Pienlo 2-8-2 Locomotives in China
Class Details by Steve Llanso of Sweat House Media
Class unknown (Locobase 14639)
Data from DeGolyer, Volume 60, pp. 172; and "China Railways JF" in Wikipedia at [
], last accessed 19 March 2023.. Works numbers were 51428-51431 in February 1919.
This Chinese railway was financed by Belgian interests. Or maybe Dutch. The railway, which was begun in 1921, ordered 151 bridges from "Holland" (according to a contemporary account). This Eddystone quartet were relatively plain engines. The firebox had no additional heating devices like arch tubes. Eleven-inch (279 mm) piston valves actuated by outside constant-lead gear admitted the steam.
Beginning in the 1930s, this major East-West railway suffered continuing damage as the combatants in the Great Pacific War pressed their attacks. It was only in the late 1940s-1950s that the railway would finally reach its 1,093 mile (1,760 km) length.
