Add automatic reversing and animation to a layout or display. The DZ-1240 Auto Stop & Reverse Module automatically senses trains with e-units at the end of the line and reverses them after a time delay. Trains can also be stopped and started automatically along the route without using sensors or isolated rails. The module can also be programmed to activate a horn or whistle at one or more locations along the route. • Activates horn and whistle sounds • No need for midpoint sensors or isolated rails • Selectable time delay
