Chongqing Rail Transit

(Redirected from Chongqing metro)

The Chongqing Rail Transit (branded as CRT; also known as Chongqing Metro) is the rapid transit system in the city of Chongqing, China. In operation since 2005, it serves the transportation needs of the city's main business and entertainment downtown areas and inner suburbs. As of December 2023, CRT consisted of eleven lines, with a total track length of 523.68 km (325 mi).[4] Lines 1, 4, 5, 6, 9, 10, 18, the Loop line and Jiangtiao line are conventional heavy-rail metro lines, while Lines 2 and 3 are high-capacity monorails. To keep up with urban growth, construction is under way on Line 18 and several other lines, in addition to extensions to Lines 5, 6 and 10.

The Chongqing Rail Transit is a unique transit system in China because of the geography of Chongqing being a densely-populated but mountainous city, with multiple river valleys. Two lines use heavy-monorail technology, leveraging the ability to negotiate steep grades and tight curves and rapid transit capacity. They are capable of transporting 32,000 passengers per hour per direction.[5] However the busiest section of Line 3 reaches a peak passenger volume of 37,700 pphpd in 2019.[6] At 98 km (61 mi),[7] the system's two monorail lines form the longest monorail system in the world,[8] with the 56.1 km (34.9 mi) Line 3 being the world's longest single monorail line even if the 11.0 km (6.8 mi) Konggang branch is excluded.[9][10] The length and the capacity of its monorail network both also make it the world's busiest monorail system, with a total of 94 million and 250 million rides in 2015 on Line 2 and Line 3, respectively.[11] The latter ridership statistic for Line 3 also makes it the world's busiest single monorail line.

The extreme difference in elevation between the river valleys and the hilly plateaus of Chongqing pose a unique challenge in designing alignments for conventional rail transit lines. The network currently has the world's highest metro-only bridge, the Caijia Rail Transit Bridge for Line 6, spanning the Jialing River valley, with the bridge deck being approximately 100 m (328 ft) above the water.[12] Hongyancun station is the deepest metro station in China and the deepest metro station in the world with the station reaching 116 m (381 ft) below the surface,[13][14] surpassing the Kyiv Metro's Arsenalna station. Hongtudi station and Liyuchi station, both on Line 10, are the second and third deepest stations in China, being 94 m (308 ft)[15] and 76 m (249 ft)[16] below the surface respectively. Additionally, Hualongqiao station is a six story structure that has Line 9 trains stopping 48 meters above the surface,[17][18] making it the tallest metro station in the world, surpassing Smith–Ninth Streets station in New York.

The Chongqing Rail Transit system possesses a number of extremely-long metro-only bridges. The 1,650 m (5,413 ft) long Egongyan Rail Transit Bridge carries the southern arc of the Loop line across the Yangtze River using a 600 m (1,969 ft) long suspension main span, making it the longest metro-only suspension bridge by main span in the world.[19] The Nanjimen Bridge carries Line 10 trains across a 1,225 m (4,019 ft) cable-stayed bridge with a main span of 480 m (1,575 ft), making it the longest metro-only cable-stayed bridge by main span in the world.[20] The Gaojia Huayuan Jialing River Rail Transit Bridge carries the western arc of the Loop line over the Jialing River using a long 594 m (1,949 ft) bridge with a main span of 340 m (1,115 ft).[21] Additionally, Chongqing Rail Transit system has numerous double-deck bridges carrying vehicle and metro traffic, such as the Chaotianmen Bridge, which is the world's longest arch bridge.

Loop line

edit
Main article: Loop line (Chongqing Rail Transit)

The Loop line (coded as "Line 0") is a rapid transit loop line.[24] The northeastern section was opened on 28 December 2018. The southern section with the Egongyan Rail Transit Bridge opened on 30 December 2019.[25] Three major railway stations in Chongqing are also linked by this line: Chongqing North railway station, Shapingba railway station, and Chongqing West railway station. Loop Line's color is yellow.

Line 1

edit
Main article: Line 1 (Chongqing Rail Transit)

Line 1 runs 16.4 km (10.2 mi) from Chaotianmen, in the central west, to Shapingba and then to Bishan with a total length of 44.5 km (27.7 mi). It is the first heavy-rail subway line in Chongqing and the second in Western China. The passenger capacity is 36,000 passengers per hour in each way. The line serves as the system's backbone connecting the densest areas including the main Central Business Districts of Jiefangbei, Lianglukou, Daping, and Shapingba. It is the first conventional subway, running in a deep-bored tunnel below Yuzhong and Shapingba Districts.

Line 1 has transfer interchange stations with Line 6 at Xiaoshizi and Line 2 at Jiaochangkou in Jiefangbei CBD and at Daping and Line 3 at Lianglukou, which is near Chongqing railway station in central Yuzhong. Line 1 is also transferable with the Loop Line at Shapingba, although out-of-station transfer is currently needed due to construction setbacks on the interchange channel and concourse connecting the two subway lines.

In 1992, the Chongqing government signed a Build-Operate-Transfer agreement with a Hong Kong company and provided the land for the project, but work ceased in 1997 because of legal issues.[26] Work resumed from Chaotianmen to Shapingba on 9 June 2009, and a limited opening occurred on 28 July 2011.[27] Thales provided an operations control centre for the line. Line 1's color is red.

Line 2

edit
Main article: Line 2 (Chongqing Rail Transit)

Line 2, a monorail line, runs 31.4 km (19.5 mi) and has 25 stations. It begins as a subway under downtown Jiefangbei, then runs west along the southern bank of Jialing River on an elevated line, and then turns south into the southwestern inner suburbs, looping back east, to terminate at Yudong, in Ba'nan District. It runs mostly elevated, but a 2.2 km (1.4 mi) section is underground, including three of its 18 stations in the Jiefangbei CBD and central Daping areas in the extremely-dense area of Yuzhong District. Line 2 runs through four administrative districts in the central city (Yuzhong, Jiulongpo, Dadukou, and Ba'nan). In 2010, Line 2 served 45 million passengers.[28] It also runs through Daping CBD, Yangjiaping CBD in Jiulongpo District, and Chongqing Zoo at. Most trains have four cars, and six-car trains began to operate in September 2012.[29] Line 2 is the first rapid transit line to open in the Interior West of China, in 2005. In 2013, six-car trains are being implemented because of overcrowding and increasing demand.[30] Line 2's color is green.

Ticketing

edit

Transport cards

edit

CRT accepts Life & Transport Card (Chongqing Universal Card, released by Chongqing City Card Payment Co., Ltd.) and its compatible cards, released by partner companies in other cities of China. There is a 10% discount applied to the Regular Card if it is used on public transit in the city. The higher price is paid for transfers between the bus and the metro within 1 hour (not including metro-to-metro, according to the paying time). The Regular Card can be purchased at any CRT station, and a deposit can be recovered when the card is returned with its receipt. In addition the card can be used in many shops, cinemas, restaurants, etc. in Chongqing. The Students' Card and the Elders' Card can not be directly used on the metro since their monthly fee covers only buses unless a cash sub-account, which allows a 50% discount, is added to the cards for free at the service points.

Time limit

edit

All trips must be completed in 3 hours upon entering the fare-paid area, or the highest ticket price in the system will be charged in addition.[37]

Operation

edit

During times of heavy use like for major events, CRT may close some stations to avoid overcrowding. In 2018, CRT closed Xiaoshizi, Jiaochangkou, Qixinggang, Lianglukou, Xiaolongkan, and Shapingba stations of Line 1; Jiaochangkou and Linjiangmen stations of Line 2; Lianglukou, Huaxinjie, Guanyinqiao, and Hongqihegou stations of Line 3; Shangxinjie, Xiaoshizi, Grand Theater, Jiangbeicheng, and Hongqihegou stations of Line 6 after 20:00 on Christmas Eve, Christmas Day, after 19:00 on New Year's Eve. And they also closed Shapingba and Shangxinjie stations of Loop line after 19:00 on New Year's Eve.[citation needed]

From 9 to 12 November 2018, they closed Grand Theater and Jiangbeicheng stations from 10:00 to 15:00 because of heavy use during Flower Expo; from 1 to 7 November 2019, they closed Grand Theater and Jiangbeicheng stations since 10:00 till 16:00 because of heavy use during Flower Expo.[citation needed]

Accessibility

edit

Almost every station has accessible elevators and toilets, and almost every train has wheelchair locks. Only the oldest rolling stock and toilets of Line 2 are not fully accessible. In addition, many older interchange channels between lines are not designed with accessibility in mind, which means the disabled there must transfer via the main concourse.[38]

Luggage rack

edit

The trains on Line 10, which links Jiangbei Airport and Chongqing North railway station, are equipped with a luggage rack on each car.[39]

History

edit

The CRT is part of the central government's project to develop the Western regions. The Japan Bank for International Cooperation provided some of the funding.[40] Construction was carried out, with co-operation between Changchun Railway Vehicles Co. Ltd. and Hitachi Monorail, which used advanced Japanese monorail technology.[41] Construction on Line 2 began in 1999, and the line was officially opened in June 2005 from Jiaochangkou (Jiefangbei CBD) to Zoo (Chongqing Zoo).

Early concepts and attempts

edit
  • 1946 plan: The Nationalist government made a plan of high-speed tram system. The rail weighs 47.77 kg/m, with a rail gauge of 1000 mm, a maximum slope of 9%, a minimum radius of curvature of 80 m (262 ft). The top speed is 25 km/h (16 mph) in the urban area and 45 km/h (28 mph) in the suburban area. The train was 8 m long, 1.8 m wide, with two 35-horsepower motors and a trailer. Each train took 240 passengers. The headway was designed to be 10 minutes. The system was expected to carry 1 million passengers per day. Some of the tracks were underground.
    • Line A, Longmenhao – Ciqikou, 9 stations, 14.75 km (9.17 mi)
    • Line B, Longmenhao – Nanwenquan, 7 stations, 19.49 km (12.11 mi)
    • Line C, Longmenhao – Datiankan, 3 stations, 6.9 km (4.3 mi)
  • 1958 attempt: "Yuzhong District Subway Engineering Unit" was started in late 1958, only to be suspended one year later.
  • 1960 plan: A 100 km-long (62 mi) underground rapid rail transit system, linking the city center with Xinpaifang, Xiaolongkan, Yangjiaping, Shiqiaopu, Lianglukou, and other populated areas, was planned.
  • 1965 attempt: The unit was reinstated. It has 4 units, including more than 1000 workers in total. Construction was stopped again in late 1966 by the Cultural Revolution. The unit was officially disbanded again in 1971. The completed tunnel sections were taken over by the civil air defense authorities.
  • 1983 plan: A 12.2 km-long (7.6 mi) subway line (Chaotianmen – Yangjiaping) was planned. It is the precursor to today's Line 2.
  • 1988 attempt: Some Hong Kong businessmen arrived to start a metro company in Lianglukou. The tunnel from previous attempts were extended.[26]
  • 1991 plan: A 4-line 55 km-long (34 mi) monorail system was planned.

Official long-term plans

edit
  • 1998 plan: Has 5 lines in total, with a length of about 119 km (74 mi).
  • 2003 and 2007 plans: Two similar expansion including 10 lines, with a total length of about 522 km (324 mi). Line 4 in the previous blueprint received a huge update and was renamed to Loop line, according to its new shape.[26]
  • 2011 plan: Features 8 new lines, with a length of about 820 km (510 mi).[42]
  • 2019 plan: Target a 30-line network as of 2050, with a length of about 1,473 km (915 mi).[43]

Visual design

edit

Unlike most metro systems of other cities in China, CRT did not follow the design style of MTR Corporation in Hong Kong. The signage system was designed by GK Design Group in Japan, and the monorail lines are based on Hitachi Monorail technology. That gives the Chongqing Rail Transit a distinctive Japanese aesthetic, in contrast to other metro systems in China.[47]

CRT also gave each line a theme about the local culture, and the stations on the line will have some art works in the theme.[48]

     Line 1 City spirit
     Line 2 Bashu culture
     Line 3 Folk life
     Line 4 Arts
     Line 5 Provisional capital era
