This hookup will allow two trains to alternate. When one train enters a siding it will hit a sensor which will stop the train.
After the programmed delay the other train will go in the opposite direction.
Both turnouts are wired in parallel and attached to the TURNOUT terminals of the YardMaster.
The YardMaster will switch when the train is clear of the sensor. This will prevent the train from parking on the sensor.
The sensors have no polarity. See the power page for input power requirements.
If DC trains are run and acceleration and deceleration is desired consider using a StationMaster instead of this
hookup. It is also a much easer hookup.
Enhancement Ideas:
1. Program a lap count for each train to do multiple laps before switching.
2. Add a signal light.
