Remarkable comprehensive energy-saving effect

Chongqing Rail Transit Line 9 adopts a regenerative energy-absorbing device, which not only ensures the safe driving of trains but also saves electric energy, and the comprehensive energy-saving effect is remarkable.

The stations via the Line 9 adopt green, environmentally friendly, and energy-saving LED lamps for the first time, optimizing the number of normal lighting lamps. The public area embraces an intelligent lighting control system with good energy-saving and environmental protection benefits.

Line 9 also chooses multiple types of fire detection equipment to realize fire detection and alarm in different environments in a timely manner. The system has high reliability and effectively reduces property losses.

Chongqing Rail Transit Line 10 crosses the Yangtze River and the Jialing River and passes through many buildings' underground space. 

To reduce shock and noise, seamless tracks are used throughout the line, and steel springs, shock-absorbing pads, and other shock-absorbing measures are installed in the areas sensitive to vibration and noise, further reducing the surrounding vibration and noise pollution and protecting many cultural relics and old houses in the area. 

Considering the travel needs of the disabled

Particularly, Huashigou Station of Line 9 adopts the form of stilted buildings, a typical mountainous building in Chongqing. 

The first floor is the platform, and the second floor is the station hall. It integrates the terrain with a height difference of nearly 20m, which is convenient for the passengers to connect to the station. 

As for the People's Auditorium Station on Line 10, the interior decoration design is inspired by Chongqing Auditorium, surrounding schools, and other characteristic buildings. The vast cultural wall of Chongqing People's Auditorium allows passengers to quickly integrate into the cultural atmosphere of Yuzhong District when they arrive at this station.

The station design of Line 10 fully considers the travel needs of the disabled, mothers and infants, and the elderly.
