I've made some pretty good progress on my RFID train detection scheme. It is now very reliable and I feel comfortable leaving the layout room (but not going to far!).
Three new videos on my web page http://www.silogic.com/trains/RFID.html
videos #13, 14 and 15. For higher resolution videos, go to my YouTube page:
In video 15, I've moved the RFID detectors to my layout (from the carpet) and show the RTC program along with the detectors running three trains. I used this during my TTOS SP Layout Open House Tour on the 28th of last month. The program kept 3 trains running on my layout for 4 hours while I talked with the visitors.
