The China Railways JS ({{zh|s=建设|p=Jiàn Shè|l=Construction or Development}}) are 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 was developed at the Dalian locomotive works by combining the chassis of the China Railways JF with a new boiler.{{cite web |last=Cotterill |first=Duncan |url=http://www.railography.co.uk/info/cn_steam/profiles/js.htm |title=JS Class 2-8-2 |website=Railography |date=7 September 2015 |access-date=9 September 2018}}{{cite web |last=Cotterill |first=Duncan |url=http://www.railography.co.uk/info/cn_steam/profiles/jf.htm |title=JF Class 2-8-2 |website=Railography |date=7 September 2015 |access-date=9 September 2018}} 1135 locomotives were produced from 1957 to 1965 at Dalian, Qishuyan Locomotive and Rolling Stock Works, Datong locomotive works, and the Beijing 7th Feb works. Dalian and Qishuyan manufactured over one thousand.
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,. The second tranche received numbers starting from 8001.{{citation| url=http://www.china.com.cn/news/txt/2008-07/16/content_16020521_17.htm| title = 建设（JS）型5001号蒸汽机车|trans-title='Construction' class steam locomotive, JS-5001| language=zh| work = www.china.com.cn}}
In total, 1,916 JS locomotives of all types were produced.
In the late 1980s, the Boone and Scenic Valley Railroad of Iowa, US, bought JS-8419 for $355,000.{{citation| url =http://www.readingtimes.com.tw/timeshtml/authors/railroad/museum/sl.htm| script-title=zh:在美國的中國建設型蒸汽機車|trans-title=Construction class steam locomotive in the USA | language=zh| work = www.readingtimes.com.tw}}
The last JS class, JS 8089 that operated at Sandaoling, was retired from service on 15 January 2024.{{Cite web |last=沙湖-sta |title=中国最后的蒸汽火车退役了。_哔哩哔哩_bilibili |url=https://www.bilibili.com/video/BV1VN4y1p7UX/ |access-date=2024-01-16 |website=www.bilibili.com |language=zh-Hans}}
Numbering
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.
