After sitting on a storage shelf for several years, I was finally able to install my Iowa Scaled Engineering reversing module. The module was custom built for me so that I could have a train running on the point-to-point branch without having to control it. The system consists of an Arduino and keypad that ties in with two ISE infrared sensors on each end of the layout. It works separately from my ESU CabControl, so I have the system isolated from the regular DCC when in use.

It works great. The train moves across the layout at a speed I designate, then after tripping one of the sensors it slowly decelerates and changes direction. It’s enjoyable to work on the layout with a train moving.

The reversing module is set into the fascia with a 3D printed faceplate. The two toggle switches on the right control power to the unit and to the track.
The IR sensors were easy to install and wire. This one is on the Andalusia Sub. side. You can see I wedged part of a wood tie to the left of the sensor to snug it in the hole. I will eventually hide the sensors with some added ballast (see below) and perhaps some grimy PanPastels to camouflage even further.
