- Tianjin Metro Line 1's old trains use Mitsubishi traction system, MAP-164-75VD138 as traction inverter and MB-5114-A as motor. In the localize experiment carried out on train set 123#, the traction inverter was replaced by Zongheng's TKQ509SA-2000, so the train's motor sound is different. Recently the VVVF program was changed, the asynchronous modulation has a much higher carrier frequency than before.
