The method is used in subway construction in other countries as it cuts the construction cost and it saves energy. The subway system is the first in China to adopt such a ventilation system during construction.

Reloadable IC cards

The Tianfutong Pass is a reloadable IC Card accepted by the Chengdu Metro.[108] Normal Tianfutong Passes provide 10% discounts. Student Tianfutong Passes provide 50% discounts. Senior Tianfutong Passes have special discounts depending on time of use.[109][108] Additionally, passengers can pay for single rides directly using Debit IC cards offered by participating banks.[110][111]

Train types and technology

All "standard" Chengdu Metro lines in operation run on 1,500 V DC supplied by overhead lines.[112][113][114] Express lines meanwhile run on 25 kV AC to get to top speed quicker. Trains on Lines 3, 4, 7, 10 and some of the newer Line 2 trains have a Golden Sun Bird insignia. New trains are equipped with LCD passenger information systems.

Line 6 Train LCD Passenger Information System

Signaling system

All Chengdu Metro lines are equipped with CBTC.[115] Chengdu Metro Line 1, which opened to traffic in 2010, used a CBTC signaling system provided by Zhejiang Zhonghe Technology, a subsidiary of Zhejiang University,[116] in collaboration with Ansaldo STS.[117] This system is also used on Chengdu Metro Line 6[118] and 10.[119] Chengdu Metro Line 3, which opened in 2016, was one of the first adoptions of a domestic CBTC signal system implementation by Beijing Traffic Control Technology.[120] Beijing Traffic Control Technology's CBTC system is also used in Line 5.[121] Alstom's Urbalis 888 CBTC signal system in collaboration with CASCO is used on Line 18, 19, Chengdu Light Rail Line 2 and the fully automated GoA4 Line 9.[122]

Type A trains

In response to congestion and high ridership, Lines 7, 8 and 10 are equipped with higher capacity 6-car aluminum alloy Type A trains. The total length of 140 metres (459 ft 4 in) and width is 3 metres (9 ft 10 in). All trains have a maximum operating speed of 80 km/h (50 mph). The capacity of a 6-car train is 1,828 passengers with a crush load capacity of 2,488 passengers. Line 7 trains are designed and managed by CRRC Qingdao Sifang with CRRC Chengdu performing manufacturing and assembly.[123] Lines 5, 6 and 9 are equipped with even higher capacity eight car aluminum alloy Type A trains. The capacity of an eight car trainset is 2,480 passengers with a crush load capacity of 3,456 passengers.[124]

Type B trains

Lines 1, 2, 3 and 4 use six car stainless steel Type B trains with a total length of 120 metres (393 ft 8 in) and width 2.8 metres (9 ft 2 in). The capacity of each train set is 1,460 people with a crush load capacity of 1,880 passengers.[125] All trains have a maximum operating speed of 80 km/h (50 mph). Lines 1 and 2 use CRRC Qingdao Sifang and CRRC Chengdu trains.[126] Trains on Line 3 and 4 are manufactured by CRRC Changchun Railway Vehicles and CRRC Chengdu.[127] In 2008, Chengdu Metro in anticipation of the opening of Line 1, purchased and initial order of 17 six car trains sets from CRRC Qingdao Sifang.[128] In April 2011, a further order was announced for trains from CRRC for Line 2, taking the total to 59 six car sets.[129]

Light Rail trains

Currently, only Chengdu Light Rail Line 2 is in operation. Light Rail Line 2 uses low floor light rail trains provided by domestic manufacturer CRRC. The tram system uses light rail trains, of each having 5 cars and 8 doors. Chengdu Light Rail Line R2 opened to public on 26 December 2018 and extended on 27 December 2019. It is 39.3 km (24.4 mi) long, with 35 stations (47 station when completed). In early 2020, this line is included in the latest Chengdu Metro's official system map.[130][131][132]

Other rail transit

High-speed intercity rail

There are also two high-speed intercity railways in Chengdu, not part of Chengdu Metro system: the Chengdu–Dujiangyan intercity railway and Chengdu–Pujiang intercity railway. They are operated by Chengdu Metropolitan Railway Company Limited, which is China's first joint venture between a local government and China's national rail operator. The city and the Ministry of Railways worked together in building high-speed intercity rail lines.[133]
