The China RailwaysJS (Chinese :建设 ;pinyin :Jiàn Shè ;lit. 'Construction or Development') are a type of2-8-2 tender steam locomotive manufactured for use on mainline freight trains, as well as for heavy shunting.
The JS was developed at theDalian locomotive works [ 4] by combining the chassis of theChina Railways JF with a new boiler.[ 3] [ 6] 1135[ 5] locomotives were produced from 1957[ 4] to 1965[ 5] at Dalian,Qishuyan Locomotive and Rolling Stock Works ,Datong locomotive works , and theBeijing 7th Feb works . Dalian and Qishuyan manufactured over one thousand.[ 4]
A second tranche was produced from 1981 to 1988. 358 were manufactured by Datong from 1981 to 1986. 434 of a revised 'B' specification were manufactured from 1986 to 1988,.[ 3] The second tranche received numbers starting from 8001.[ 1] [ 2] [ 3]
In total, 1,916 JS locomotives of all types were produced.[ 1] [ 2]
In the late 1980s, theBoone and Scenic Valley Railroad ofIowa , US, bought JS-8419 for $355,000.[ 7]
The last JS class, JS 8089 that operated at Sandaoling, was retired from service on 15 January 2024.[ 8]
Locomotives produced from 1957 to 1965 were numbered JS-5001 to JS-6135. Starting at 5001 avoided overlapping the numbers of the various types of JF occupying the 1 - 4100 (approx) range. 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]
