The China railways JS class (建设, JianShe construction) was a type of 2-8-2 tender steam locomotive manufactured for use on mainline freight trains, as well as for heavy shunting.
History
The JS class was developed at the Dalian locomotive works;[4] the design used the chassis design of the China Railways JF class, with a new boiler type.,[3][6] The first locomotive was produced in 1957; subsequently Dalian work and Qishuyan locomotive works produced over 1000 of the class, Datong locomotive works, and the Beijing 7th Feb works also manufactured vehicles.[4] By 1965 1,135 vehicles had been made.[5]
A second production phase began in 1981; Datong produced 358 locomotives by 1986. In 1986 a revised 'B' specification was introduced, and 434 units of this type were made; construction ended in 1988.[3] the second tranche of locomotives received numbers from 8001 upwards. By the end of production 1916 units have been produced of both series combined.[1][2][3]
In the late 1980s the Boone and Scenic Valley Railroad of Iowa, USA bought a JS type locomotive for $355,000, number JS-8419.[7]
Locomotive JS-5001, built 1957, has been preserved at the China Railway Museum.[8]
Numbering
Locomotives produced from 1957 to 1965 were numbered JS-5001 to JS-6135. Locomotives produced at Datong in the early 1980s were numbered JS-6201 to JS-6558; after the introduction of the revised 'B' specification the locomotives were numbered JS-8001 to JS-8423. A small number of locomotives operating outside the scope of the ministry of railways (industrial railways) received different number designations.[3]
