Switch GREEN
 Sensor

AC, DC, or DCC trains can be  controlled.

Make sure to program the YardMaster for the desired time delay.
Program a lap count if desired.

When the power supply is turned on the train should run. If it does not then press the
Alternate button. This is a one-time operation since the YardMaster will remember the switch state in
memory.

Change direction of the train as desired. The YardMaster will operate in both directions.

Adding a signal light is optional, but adds to the fun.

For gradual decelerations and accelerations consider using a StationMaster for a station stop

Parts List

YardMaster          1
Track Isolators     2
Train Sensor        1
Train magnet       1
wire as required

This is basically the same hookup as a standard station stop in a loop
however it uses the track power as the voltage input to the YardMaster.
Add this to a remote location on your railroad without stringing wires to the
remote section.  Trains can run in either direction  Track power must be 8 volts or more.. 

The sensor provides an exact stopping location. A train magnet is required.
