In existing urban rail transit system, because of long construction period, train-ground communication system for different rail lines may use equipment from different manufacturer, that will bring challenges for management of metro company, even, it may result in emergency brake of train or traffic safety when a train is going across different lines. In this paper, we first study relevant demands of TD-LTE train-ground communication interconnection, an interconnected TD-LTE train-ground communication system for the urban rail transit system is designed next, in order to test the interconnected TD-LTE based train-ground communication system performance, an indoor testing environment is set up. The programmable attenuators and EIT-Monitor are used to simulate the real urban rail transit environment and monitor signal from different network equipment. Final test results prove that the designed interconnected TD-LTE train-ground communication can be applied to current train control system, which completely satisfies the demand of subway operation in urban rail transit system.
