CHONGQING (CQNEWS) -- Chongqing Rail Transit construction will speed up again! The reporter learned from Chongqing Traffic Report Group, recently, the construction of phase II project of urban rail express line 15 has been officially started, and it is expected that the whole line of urban rail express line 15 will be opened to traffic by the end of 2026.
It is expected that the whole line will be opened to traffic by the end of 2026.

Combined with the actual engineering practice, it focuses on Station-Municipal integration, traffic connection, humanized service, green energy conservation, intelligent operation and maintenance, cultural design, etc.
In terms of intelligence, the second phase of Line 15 adopts technical systems such as intelligent station and full-automatic operation system. For example, the vehicle is equipped with passenger intelligent service system to display the car congestion, and to present the location of station toilet, escalator, entrance and exit, and to show the outdoor climate information, etc. Moreover, the vehicle is equipped with intelligent on-board air conditioner to automatically adjust the air temperature and humidity in the vehicle according to the internal environment and the number of passengers.
