Reference:[1]

The China Railways KD7 are a type of 2-8-0 "Consolidation" type steam locomotives.[1] The KD7 locomotives were built in the United States and supplied to China by UNRRA as part of the post war rehabilitation effort in 1946.[1] China received 160 locos while others of the same design went to Belgium as NMBS/SNCB Type 29.[1]

In the late 1970s, China began retiring the KD7's and replacing them with JS classes, the last KD7 was used in mainline service in 1988.[1]

At least four KD7s are thought to have been preserved.[1] KD7 534 is at Beijing Railway Museum, KD7 587 is at Shanghai History Museum[2] and KD7 641 is at Shanghai Railway Museum and KD7 513 at the Datong Locomotive Works Museum.[3][1] A fifth loco, KD7 511, was reported to be under restoration in Hangzhou in 2002.[4][1]
