Line 9 (Beijing Subway): Difference between revisions

In 1989, the State Council decided to build [[Beijing West railway station]] on the [[Beijing–Kowloon railway|Beijing-Kowloon railway]]. Subway planning had determined that Beijing West railway station would be the interchange between Lines [[Line 7, Beijing Subway|7]] and 9. However, no provision for an interchange station was added in the railway station's design. The railway station was completed in 1996.<ref>{{cite web|url=http://www.buedri.com/voteproject/doc/20.doc |script-title=zh:北京西客站预埋工程|publisher=北京城建设计研究总院 |access-date=2013-01-19|format=doc}}{{dead link|date=December 2017 |bot=InternetArchiveBot |fix-attempted=yes }}</ref> 15 years later Beijing West Station was rebuilt and expanded with provisions added to the basement of the station for Lines 7 and 9.<ref>{{cite news|url=http://www.gov.cn/jrzg/2011-05/03/content_1856871.htm |script-title=zh:"五一"期间北京市万名地铁建设者坚守岗位|date=2011-05-03|access-date=2013-01-19}}</ref> In 2002, in preparation for the [[2008 Summer Olympics|2008 Beijing Olympics]], it was proposed that the first section of Line 9 should be built between Baishiqiao and Beijing West railway station (today's National Library to Beijing West railway station section).

In the meantime, planners were investigating the possibility of extending Line 9 northwest beyond Baishiqiao and roughly paralleling the almost complete [[Line 4 (Beijing Subway)|Line 4]]. However, this Baishiqiao-Wenyang Road Project would head further north to the Haidan area, terminating around the Wenyang Road (温阳路) exit of the [[6th Ring Road]] competing with another proposal where Line 4's northern extension would serve the area. The extension project was would be 25.5 &nbsp;km long and add 13 new stations, creating a 40.7 &nbsp;km long Line 9.<ref>{{Cite web|title=北京地铁9号线有望北延 连接海淀北部与中心区-搜狐新闻|url=http://news.sohu.com/20100112/n269507156.shtml|access-date=2021-10-05|website=news.sohu.com}}</ref> However, this project was cut back to the current terminus at {{stl|BJS|National Library}} Station with the remaining sections north was ultimately redesigned as neither Line 9 or Line 4 but replaced by [[Line 16 (Beijing Subway)|Line 16]].
