Recently, the train for the Chongming Line of the Shanghai Rail Transit Regional Line officially rolls off at CRRC ZELC. This project is the first in Shanghai to adopt an integrated bidding model of "vehicle procurement plus long-life maintenance," marking a significant step forward for Chongming Island’s integration into the metro network.
The Chongming Line train adopts a 3-car all-motor configuration, and is equipped with the GoA4 fully automatic driverless system. It features intelligent functions such as automatic coupling and decoupling on the main line, with a top speed of 120 km/h.
The train is fully equipped with new-technology products such as silicon carbide auxiliary inverters and oil-free compressors. Compared with traditional equipment, the silicon carbide auxiliary inverter is greener and more energy-efficient, and features a 45% reduction in weight, an efficiency increase to 96%, and an energy density improvement of over 150%.
This train deeply integrates ecological features with traditional culture. Guided by the concepts of "ecology, agility, intelligence, and sharing," it is designed into an "eco-island” with use of the eco-friendly materials. In terms of technological innovation, the train features safety, intelligence, and efficient operation and maintenance.
It is reported that the Chongming Line, as the longest rail transit line in China crossing the Yangtze River, spans 42.232 kilometers and connects eight stations along the route from Pudong to Changxing Island and Chongming Island. Upon completion, it will effectively facilitate Chongming’s full integration into Shanghai’s comprehensive transportation system and contribute to achieving more extensive coverage of rail transit across the Shanghai metropolitan area.
