China News Service, Chengdu, September 27th (Reporter Liu Zhongjun) Chengdu Rail Transit Line 18, which runs at a speed of 140 kilometers per hour, officially opened for initial operation on the 27th. This is currently the fastest subway line in the country to enter the central city area, marking Chengdu Rail Transit Enter the fast-track era.
The theme train of Chengdu Rail Transit "Construction" appeared.

It is understood that Line 18, as the first aorta in Chengdu’s eastward strategy, connects Chengdu’s main urban area, Tianfu New District with Eastern New District and Tianfu International Airport for the first time.
The line 18 that opened this time starts from the South Railway Station in the north and runs south along the east side of Tianfu Avenue. It passes through the Global Center, Century City, and Lushan to the Tianfu New District Expo City area, and then crosses Longquan Mountain to the east to Sancha Lake area. It is 55.95 kilometers long and has 9 stations, including 1 elevated station, 8 underground stations, and 5 transfer stations.
As the fastest urban express line entering the central city in the country, this line uses 8 A-type marshalling vehicles with a speed of 140 kilometers per hour for the first time, considering the integrated operation of dual airports, and reserves the highest speed per hour on the common line of Line 18 and Line 19. Operating conditions of 160 kilometers can realize the interconnection with Line 19 and S3, realize the "30-minute Chengdu Rail Transit Circle" and form a "1 hour Chengdu Rail Transit Living Circle".
The "Jianjian" theme train introduced the development of Chengdu Metro in detail through the pictures posted.

For the first time on Line 18, 8.6-meter large-diameter shield machines were used in water-rich sand and pebble formations. The maximum daily excavation of a single machine was 28.8 meters and the highest monthly excavation reached 452.5 meters, setting a national historical record for large-diameter shield tunneling speed.
The biggest engineering problem in the construction of Line 18 is the need to overcome the longest high-gas-gas long tunnel in the history of urban rail transit construction in China-the Longquanshan Tunnel with a length of about 9.7 kilometers.
The tunnel intensively passes through the oil and gas storage areas of Su Wharf and Luodai Gas Field. Because of its large gas escape, high degree of dispersion, and extremely high risk of inrush, it is very rare in domestic urban rail transit construction.
At the same time, LTE_U technology was used as the vehicle-to-ground broadband wireless communication technology in rail transit for the first time, realizing the highest-speed vehicle-to-ground wireless communication in China.
Chengdu Rail Transit Line 18 has set up toilets and blind tracks at the platform to provide convenience to citizens and blind passengers.

In addition, for the first time, the Art Station of Line 18 adopts a spatial integration method. The blue and green colors represent the blue sky and the green grassland, nurturing everything in the world, integrating nature and urban rail transit, reflecting the tolerance and open-mindedness of the people in Chengdu.
Century City Station presents a "golden track" scene.

Currently, Chengdu Rail Transit has opened and operated nearly 400 kilometers (including 39.3 kilometers of trams).
The first and second phases of Metro Line 6, the third phase of Line 6, the first phase of Line 8, the first phase of Line 9, the first phase of Line 17, and the subsequent projects to be opened on Line 18 have all entered the no-load trial operation stage.
It is estimated that by the end of 2020, the total mileage of Chengdu rail transit will reach 557.8 kilometers, and the scale of the line network will rise to the "first square" of rail transit in the country.
By then, Chengdu will also become a metro city with the fastest domestic rail transit operating mileage exceeding 500 kilometers.
It is reported that 2020 is the 15th anniversary of the construction of Chengdu Rail Transit, and the first "Jianghe" theme train built is also officially unveiled on Line 18. The train passes "Time", "Secret", "Wuwen" and " The four chapters, including "Gorgeous Chapter", fully reproduce the glorious history of Chengdu rail construction in the past 15 years and the hard work of the rail builders, opening a "window" for urban rail transit to the general public.
