Hours of operation

The first east-bound trains departs from Gucheng at 4:58am and Pingguoyuan at 5:10am. The first west-bound train departs Sihui at 4:56am and Sihui East at 5:05am. The last east-bound train leaves Pingguoyuan at 10:55pm. The last west-bound train leaves Sihui East at 11:15pm. For the official timetable, see.^[7]

Route

Line 1's western terminus is {{BJS stations|Pingguoyuan}}, located in the Western Hills of Shijingshan District. The line heads southeast to its second stop at Gucheng and from there runs straight east, following Chang'an Avenue all the way to its eastern terminus, {{BJS stations|Sihui East}} in Chaoyang District, just beyond the 4th Ring Road. The line passes through Xidan, Wangfujing and Dongdan, among other important commercial centers of Xicheng and Dongcheng Districts, as well as the Beijing CBD near the China World Trade Center. The line's total operational length is {{convert|30.4|km|abbr=on}}. It has 23 stations in operation. All stations except for Sihui and Sihui East are underground.

Stations (from west to east)

History

The first section of subway in Beijing officially started trial operation on January 15, 1971. It was {{convert|10.7|km|abbr=on}} long and ran between Beijing railway station to {{BJS stations|Gongzhufen}} which today is a section of Line 1 and 2.^[9] A few months later, on August 15, 1971 the line was extended 3 stations west, to {{BJS stations|Yuquanlu}}. The line was extended again to {{BJS stations|Gucheng}} in November. On April 23, 1973, the line was extended {{BJS stations|Pingguoyuan}}, at this point the line is {{convert|23.6|km|abbr=on}} long with 17 stations.^[9] On September 15, 1981 the line was again extended westward to {{BJS stations|Fushouling}} creating a {{convert|27.6|km|abbr=on}} 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.^[10]

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, {{BJS stations|Fuxingmen}}, was completed between {{BJS stations|Nanlishilu}} and {{BJS stations|Changchunjie}} stations on December 28, 1987. The section between Changchunjie and Beijing railway stations 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 one station to {{BJS stations|Xidan}}. In 1994, Line 1's signals were upgraded to automatic train protection system.^[11] On September 28, 1999, the first section of the Fuba line between Tian'anmen East to Sihui East was opened. On June 28, 2000, the section between Xidan and Tiananmen East stations opened, merging Line 1 and the Fuba Line to create a {{convert|31|km|abbr=on}} with line 23 stations.^[11]

Due to platform congestion and suicides, a proposal was made in 2010 to refit all stations on Line 1 with platform screen doors.^[12] However, the ventilation system in the older stations of Line 1 was incompatible with full-height platform screen doors, so half height platform screen gates (PSG) were chosen instead.^[13] In the meantime between 2014 and 2015, Line 1 again upgraded its signals to a communications-based train control system allowing trains to run headways down to 2 minutes during rush hour. In 2016, the PSG was installed at Yong'anli Station.^[14] By the end of 2017, all stations were retrofitted with half-height platform screen doors, and all the screen doors were put into operation for the first time.^[15]

Other facilities

Rolling stock for Line 1 is maintained at {{BJS stations|Gucheng}} and {{BJS stations|Sihui}}.

Beyond {{BJS stations|Pingguoyuan}}, Line 1 extends further west into a military base where it has several other stations including 54# Heishitou/Wulituo ({{lang|zh-hans|黑石头/五里坨}}), 53#/No. 101 Gaojing/Beijing Military Region ({{lang|zh-hans|高井/北京军区}}) and 52#/No. 102 Fushouling/Metro Drivers' Vocational School ({{lang|zh-hans|福寿岭/地铁驾校}}). These stations are not open for public use.{{Citation needed|date=August 2014}}

Future plans

Through operations with the Batong Line

In 2010, a CPPCC member Chending Wang, 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 Sihui East or Sihui.^[16] 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.^[17]

In January 2019, it is reported that the design of the through operation is finished, and the construction to allow through operation will be started in 2019.^[18]

Increasing capacity

Due to Line 1's severe overcapacity problem, there are plans to introduce seven-car or longer trains.^[19] In order for this plan to proceed the oldest section of Line 1 between Pingguoyuan and Nanlishilu, which only has platforms long enough to accommodate six-car trains, will need to be lengthened. The newer section between Fuxingmen and Sihui East has platforms long enough for 8 car trains. Due to the high cost of extending the platforms of the underground stations the plan is currently put on hold. In the future a parallel express line called Line 18 will run beside or under Line 1 stopping only at major stations.
