According to data released by Chengdu Rail Transit, since the opening of Metro Line 1, the cumulative number of passengers carried has exceeded 6 billion, the average daily passenger volume has exceeded 4 million, and the maximum passenger volume in a single day has reached 5.5525 million. The bus travel sharing rate has exceeded 50%.
"It is estimated that in 2021, Chengdu Rail Transit will have a single-day passenger flow of 6.92 million passengers." Li Xianghong, deputy general manager of Chengdu Rail Transit Group Operating Company, said that the newly opened five lines connect Chengdu Tianfu New District and Eastern New District, and at the same time strengthen the Radiation of Chengdu Shuangliu District and Wenjiang District.

The fully automatic operation system of the first phase of Chengdu Rail Transit Line 9 has made innovative breakthroughs in core systems such as vehicles, signals, platform doors, communications, and integrated monitoring. The trains are no longer equipped with full-time drivers and are staffed by qualified personnel or The flight attendant is responsible for emergency driving in case of train failure.
"The first phase of Chengdu Rail Transit Line 9 is full of'black technology', and it is a subway full of'smart'." Wei Deyong, deputy general manager of the China Railway Second Institute, said that the line is located in the Wuqing Depot and Yuanhua Parking Lot. The control centers are set up in accordance with the one-master one-standby standard, and the core center-level equipment is configured in a one-to-one manner, which truly realizes the disaster recovery function in emergency situations and effectively escorts the safe operation of the fully automatic operation system.

The entire line of Chengdu Rail Transit Line 9 is intelligently controlled by the control center, and the train will follow the "wake-up-depart-return-sleep" process to achieve automatic control of the entire operation process.
During operation, fully automatic driving functions such as comprehensive train self-checking, automatic car washing, outgoing vehicle base, main line operation between stations, precise stop of stations, opening and closing doors and platform doors, terminal turning back, and returning to the vehicle base are fully realized.
The platform door is equipped with a "alignment isolation interlock" function, which maximizes the safety of the platform door.
"Compared with the previous urban rail lines, the signal, communication and integrated monitoring system of Line 9 has added a large number of new functions to cooperate with fully automatic operation. It can be said to be a safe line with "bright ears and eyes" and quick response." Deputy Chief Engineer of China Railway Second Institute Zhang Haibo said.

“The first phase of the Chengdu Rail Transit Line 17 project has overcome 179 major and extreme risk sources. The shield has traversed existing expressways and expressways 8 times, and traversed Fengxi River and Jiang’an River 12 times. Crossing more than 20 housing complexes at one time and crossing the existing operating railway four times.” Zhang Haibo said that in the first phase of Line 17, the new technology of “one-button switch station” was also innovatively developed and applied. The monitoring workstation operates a one-key opening or closing control command to open or close the station environmental control system, lighting, guidance, escalator, rolling door and other equipment, realizing a new attempt at remote and intelligent station operation.
The five new rail transit lines in Chengdu complement the urban rail transit network, making passenger flow more even, and at the same time alleviating the overcrowding of individual lines during peak periods.
At present, the eight projects planned for the fourth phase of Chengdu rail transit, including the second phase of Line 19, have all started construction, with a total mileage of 176 kilometers.
"The subway station is only 1 kilometer away from the community, making it easy to commute to and from get off work. You don't have to go out more than an hour earlier in the morning." said Zhang Xiaoxia, who lives near Jinhua Road in Jinjiang District, Chengdu and works in a company in the Financial City.
