Alternating Trains at a Siding, AC or DC Trains
Trains will ALTERNATE without stopping with powered turnouts.
This hookup will allow two trains to alternate. When one train enters a siding it will hit a sensor and cause the
YardMaster to switch power to the other siding. There will be no pause, just an exchange of the running train.
Both turnouts are wired in parallel and attached to the TURNOUT terminals of the YardMaster. The exiting turnout can be
powered or non-powered. (one direction only. For two directions both turnouts must be powered)
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 acceleration, deceleration, or station pause is desired consider using a StationMaster instead of this hookup.
Enhancement Ideas:
1. Program a lap count for each train to do multiple laps before switching.
2. Add a signal light
