Chongqing Rail Transit takes the lead in realizing

[Chongqing News from People’s Daily Online] On September 17, Chongqing Transportation Development Investment Rail Group announced that starting from September 18, the Chongqing Rail Transit Circle Line and Line 4 interoperable direct express trains will be put into trial operation with passengers. The train can run directly on the line at the interchange station, which is the first case in the country.

What is interconnection? That is, rail transit trains can run directly on interconnected lines. After the interconnection is realized, the same train can cross from this line to another line without stopping and without changing the driving mode. Passengers who want to go to other routes can reach their destination without getting off the bus and transfer. This not only reduces the waiting time for passengers to transfer, but also meets the diversified travel needs of passengers.

Because the technical standards adopted by the signal systems between different lines in the rail transit industry are often different, and the lines are operated on a single line and are independent of each other, interconnection has always been a worldwide problem. After several years of arduous research and preparation, the Chongqing Transportation Investment Rail Group has formulated standards and specifications for each link and level of the interconnection system, and took the lead in overcoming the technical difficulties of the interconnection and interconnection of the rail transit CBTC system.

According to the introduction, the trial operation section for the interconnection and interoperability of the Ring Line and Line 4 is Chongqing Library-Min'an Avenue-Tangjiatuo. The interval of the direct and express trains is 30 minutes, and it stops at Chongqing Library Station, Shapingba Station and Ranjia on the ring line. There are 7 stations including Ba Station, Loop Line, Line 4 Interchange Station, Min'an Avenue Station, and Line 4 Chongqing North Station North Square Station, Toutang Station, and Tangjiatuo Station. Except for express trains, the operation of other ordinary trains remains unchanged at all times. As the direct and express trains have few stops, it only takes 35 minutes to run directly from Chongqing Library Station on the Circle Line to Tangjiatuo Station on Line 4, which is about 11 minutes less than ordinary trains, which greatly saves passengers' travel time.

Passengers who need to take direct express trains can use Chongqing Rail Transit's official Weibo, WeChat public account, and station broadcasts to learn about train schedules and other relevant operational information, plan travel routes scientifically, and check the guidance signs in the station or ask about station work personnel. If passengers who need to take a regular train take a direct express train by mistake, they can get off the train at the nearest stop in time through the voice announcement and electronic display screen in the train and change to a regular train.
