How to hook it up
The hookup is here: Point-To-Point Automatic Reversing.
Hookup and operating Instructions are:
1.) Attach 2 wires from your transformer to the SHUTTLE.
2.) Attach 2 wires from the SHUTTLE to the track.
3.) Attach diodes to the ends where the train will stop.
4.) Place the train on the track and power up. The SHUTTLE will do the rest.
There are no engine modifications or sensors. Your train will slow-down, creep into the ends, pause, and then accelerate out in the other direction.
