H-Tronic 4016138059205 Shuttle train auto controller Prefab component for Z to I scale DC trains

An automatic shuttle mode on a secondary line livens up each model railway system. If the train reaches its stopping area, it is sent back on the track in the opposite direction after the set waiting time has elapsed. If the train travels in the isolating distance, the train stops accordingly for the set time and then travels back to the other end of the track. The polarity reversal for changing the direction of travel is done automatically with this component.
