I've got one and it's never been on the tracks. It's sort of amazing that RailScope pre-dates Apple's first digital camera (circa 1996) and a host of other electronic devices.
The only time I saw one in operation was at Boyd Mason's Hazlet Train Stop (NJ) layout. It was really something to see, back in the day.
I also recall that there was a good article in another toy trains magazine -- with detailed plans/electronic schematics -- for converting the unit from battery power to track power, i.e., thus eliminating the issue of lackluster and unacceptable battery life.
When I finish my layout, I'm likely to use the track-power method to show the thing off, mostly as a period piece. I think hanging that black and white television with its red plastic case will be an interesting thing to look at all by itself.
Fun.
