Stan, thank you. When I bought the FRM01's, it was some time ago and they were cheap so I bought five. As I explained before, I didn't know how to program at that time, so they got put away.

Also, while I was on the PC last night, I googled switching with transistors. I found a sight that explained how to use a PNP to control a device with the base triggered by a ground. Can I assume that the PNP could replace the first relay in your diagram?

Also for info to anyone following this thread; even if you don't have 'bouncy' wheels or poor contact track, if you don't debounce, then you must make the control rail length longer than the largest wheel span you have (I had missed this issue). I can now go with very short control rails.
