TM1 electric locomotives supplied to Teheran-Mehrsharhr line for mass transmit are coupled with double deckers to form the train unit. The formation of the push-pull train is L+10T+L.

The main circuit is comprised of three-stage uneven half controlled bridge.Thyristors are used for magnetic weakening, so stepless speed regulation is possible in the whole speed range.

Micro-computer is used for the control of locomotive. Both traction and rheostatic braking are featured by constant current and quasi-constant speed controls. Remote distance multiple operation control is achieved.

Traction motor hollow shaft frame-mounted structure is adopted for bogie. Level pull-rod is used in traction device. The air braking system adopts DK-1 electro-pneumatic braker. TVM300 unit is used for locomotive ATP system.

Train power supply inverter is installed on locomotive to supply power to the train. Train broadcasting unit, train door control unit and axle temperature alarm system are also installed.
