• On the afternoon of October 17, Shanghai Metro Line 18 held a roll-off ceremony at CRRC Zhuji.  The project train is currently the highest level fully automatic driving train (GoA4) unattended during the whole process.Shanghai Metro Line 18 was initially equipped with 50 vehicles and adopted the national standard 6-section A-type car group, with a maximum speed of 80km/h.Beihai Communication provided on-board passenger information system for Shanghai Line 18 trains. For the GoA4 level, the passenger information system can adapt to a variety of scenarios for linkage, and it fully considers reliability and redundancy. The passenger information system of this project uses a highly redundant ring Ethernet architecture, with dual switches for each vehicle and power supplied separately...
