TDY203 short retarder has great braking power, in line with department standard; no mushroom head, not topping; adapt to all types of new and old lines; collision and derailment never happened. It requires no external energy and external control. By the speed and pressure valves and other hydraulic valve structure automatically to judge the speed of the humping vehicles, and act in accordance with different speeds, so as to achieve automatic control humping vehicles speed.
