Simple AutoReverser Version3
If your DCC layout incorporates a reversing loop or wye, and you would like to run trains through this part of your track without having to stop and fiddle with electrical switches, then you are going to need a unit which automatically swaps over the connections from your DCC booster to the loop or wye sections of track.
This auto-reverser is fully electronic rather than using a relay, and is constructed with readily-available through-hole components only, so that, provided you are capable of using a fine-tip soldering iron (and are comfortable assembling electronic components on to a printed-circuit board) you can easily buy the components and build it. To keep things simple, there is no microcontroller or software programming involved, nor are there any operating adjustments to make.
