Line 1 (Beijing Subway)

Template:Short description Template:Infobox rail line Line 1 of the Beijing Subway (Template:Zh) is the oldest and one of the busiest lines of Beijing's mass transit rail network. The line runs underneath Chang'an Avenue, the city's grand east–west thoroughfare, right through the heart of Beijing with stops on either side of Tiananmen Square. Line 1's color is dark red. Through operation with the Batong line started on August 29, 2021.<ref name=bjd20210825 />

Ridership

As the oldest line of the Beijing Subway, Line 1 was also the most heavily used from the time the subway opened in 1971 until January 2013, when the near-completion of the Line 10 loop caused ridership on that line to surge past Line 1. Daily ridership averaged 1,234,900 in 2014.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Peak ridership in 2014 was 1,536,900.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}Template:Dead link</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

Recent traffic relief efforts have been completed in recent years. The opening of the first phase of the parallel Line 6, caused an 8.46% decrease in daily demand and a 10-20% reduction in peak flow during rush hour.<ref name="ridership">Template:Cite news</ref> In addition Beijing BRT line 2 parallels the eastern section of Line 1. In the meantime between 2014 and 2015, Line 1 again upgraded its signals to a communications-based train control system allowing trains to run at headways as low as 1 minutes 45 seconds. However, during peak hours, sections of the line were reported in 2013 to still operate above 100% capacity.<ref name="ridership" />

History

File:YUQUANLU Station 20181117.jpg

Yuquan Lu station, Opened on August 5, 1971. The first phase of the Beijing subway project groundbreaking ceremony was held west of Yuquanlu Road.

The first section of subway in Beijing officially started trial operation on January 15, 1971. It was Template:Convert long and ran between Beijing railway station to Template:Stl,Template:Efn which today is a section of Line 1 and 2.<ref name="地铁大事记2">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> A few months later, on August 15, 1971, the line was extended 3 stations west, to Template:Stl. The line was extended again to Template:Stl in November. On April 23, 1973, the line was extended Template:Stl, at this point the line is Template:Convert long with 17 stations.<ref name="地铁大事记2" /> On September 15, 1981, the line was again extended westward to Template:Stl creating a Template:Convert long line with 19 stations. The line was transferred to the newly created Beijing Mass Transit Operation Corporation and was officially opened to the public, ending the decade long trial operation period. By 1981, the annual passenger volume of Beijing Subway was 64.66 million passengers, with a daily average of 177,000 passenger trips.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

On August 15, 1986, the second phase of subway construction started and a feasibility study on the construction of the new line between of Fuxingmen to Bawangfen (Today's Beijing CBD) was carried out. A new branch heading east to a new station, Template:Stl, was completed between Template:Stl and Template:Stl stations on December 28, 1987. The section between Template:Stl and Template:Stl was transferred to the newly created Line 2 and Line 1 ran between Pingguoyuan and Fuxingmen stations. In January 1991, the feasibility study report on the construction of a new line between Fuxingmen to Bawangfen was approved with construction of the new "Fuba line", starting in June 1992. On December 12, 1992, Line 1 was extended east for one station to Template:Stl. In 1994, Line 1's signals were upgraded to automatic train protection system.<ref name="地铁大事记4">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> On September 28, 1999, the first section of the Fuba line between Template:Stl to Template:Stl was opened. On June 28, 2000, the section between Template:Stl and Template:Stl stations opened, merging Line 1 and the Fuba Line to create a Template:Convert line with 23 stations.<ref name="地铁大事记4" />

Headway Reduction

Since 2014, the signaling and power systems has been gradually upgraded to allow for trains to run more frequently.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> The upgraded CBTC moving block signaling system in place today reduces rush hour headways from every 2 minutes and 5 seconds to 1 minute 45 seconds.<ref name=":0">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

Platform screen doors

In 2017, platform screen doors were installed on the platform of Line 1.

Due to platform congestion and suicides, a proposal was made in 2010 to refit all stations on Line 1 with platform screen doors.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> However, the ventilation system in the older stations of Line 1 was incompatible with full-height platform screen doors, so half height platform screen doors were chosen instead.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }} 大众网 2010-07-04</ref> In July 2016, the operator began installing platform screen doors on Line 1.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> In 2016, the platform screen doors was installed at Yong'anli station.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> By the end of 2017, all stations except Template:Stl were retrofitted with half-height platform screen doors, and all the screen doors were put into operation for the first time.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

Through operations with the Batong line

In 2010, a CPPCC member Chen Dingwang, proposed that services on Line 1 and the Batong line should directly link, with through operations, reducing travel times and removing the unnecessary forced transfers at Template:Stl or Template:Stl.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> However, the Beijing Subway responded that Line 1's and Batong's signal systems are completely different, so through-operation will be more difficult to achieve, from an engineering standpoint. As of 2016, preliminary design and feasibility studies are underway to allow for through operations between Line 1 and Batong.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> On June 12, 2020, the project of the through operation of Line 1 and Batong line was approved by Beijing Development and Reform Commission.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Through operation with the Batong line started on 29 August 2021.<ref name=bjd20210825>Template:Cite news</ref>

Restricted stations

{{#invoke:Labelled list hatnote|labelledList|Main article|Main articles|Main page|Main pages}} Beyond Template:Stl, Line 1 extends further northwest where it has several other stations: Gaojing ({{#invoke:Lang|lang}}) and Fushouling ({{#invoke:Lang|lang}}). Gaojing station is in the military region. Fushouling station is actually outside the military region. These stations are not open for public use.

Fushouling station's opening date is yet to be determined.<ref name=Beijingdaily2023 /><ref name=:01>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

A proposal to open the Gaojing station to public is mentioned within 2022 and 2023 working plan of the Shijingshan District.<ref name=Beijingdaily2023>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref name=shijingshan2022>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

Future Development

Increasing capacity

File:Tian'anmen East Station End Platform.jpg

The platforms of some Line 1 stations are longer than the trains used on the line.

Due to Line 1's severe overcapacity problem, there are plans to introduce 7-car or longer trains. In order for this plan to proceed the oldest section of Line 1 between Template:Stl and Template:Stl, which only has platforms long enough to accommodate 6-car trains, will need to be lengthened. The newer section between Template:Stl and Template:Stl, formerly known as "Fuba line" during construction, has platforms long enough for 8-car trains.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>Template:Cite journal</ref> According to an interview to the director of Beijing Municipal Transport Commission in December 2022, they will introduce 7-car trains in the eastern section of Line 1 and the Batong line in future.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

Branch to Qinglonghudong

On 8 July 2022, an EIA document regarding Phase III construction of Beijing rail transport system (2022–2027) mentions a proposal about the branch line of Line 1. The branch line is a southwest-to-northeast line starts from Qinglonghudong (located at the east side of Qinglong Lake, in Wangzuo Town, Fengtai District) to Bajiao Amusement Park in Shijingshan District. It will be Template:Convert in length with 9 new stations.<ref name=Janzdb /><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Construction on the Line 1 branch began on January 18, 2024.<ref name=Janzdb>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

To facilitate construction of the extension, the project will need to renovate and expand Template:Stl Station.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> According to the second announcement of the environmental impact assessment of the Line 1 branch line project released in October 2023, this station will be a new platform for the branch line of Line 1, and the new platform will be combined with the existing Line 1 platform to form a separate island platform, so that the station will become a double-island station.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
