A simple economic DC train shuttle circuit

Shuttle Principles/Theory

There are several electronic train shuttle circuits on the market. The last time I looked, I was put off by the price of a few hundred dollars and, in my view, the electronics were over-engineered and over-specified.

I was put off by the need for external detectors such as magnetic reed switches or infrared detectors. These are unnecessary complications in my view.
