Alstom signed a contract with Nanjing Metro to provide traction systems and the train control and monitoring system (TCMS) for 318 metro cars that will run on Nanjing Line 7, the first driverless metro line in the Chinese city. Alstom, with its global experience in unattended train operation (UTO), will also provide technical review for the system.
