After the establishment of the People's Republic of China, China Railways designated them ㄇㄎ7 (MK7) class in 1951, and subsequently 解放7 (JF7) class in 1959; they were numbered in the 3601–3650, though the total number of engines is unknown.[2] JF7-3608 was seen at Yanzhou in 1981.[3]The last of these locomotives were retired in 1990.[2] References1. ^1 万国牌蒸汽机车型号 {{nctclocos}}{{Locomotives of China}}2. ^1 2 3 [https://baike.baidu.com/item/解放型蒸汽机车 解放型蒸汽机车] 3. ^[https://thetransportlibrary.co.uk/index.php?route=product/product&path=44_49_371&product_id=27295 China Railways Steam Locomotive JF7 3608 at Yanzhow in 1981]_The Transport Library 4 : 2-8-2 locomotives|Railway locomotives introduced in 1913|Steam locomotives of China|Standard gauge locomotives of China |
