| | | Dan, Very clever layout. How is the RCX deturning when to let the next train go? Is it timed or is it using a sensor to figure out if the track was clear. I would be curious to see how this worked with longer trains, ones with a few pieces of (...) (24 years ago, 14-Aug-00, to lugnet.trains)

| | | | | | I like the angled sensor idea also. As for my delayed sensor, I actually had two sensors and both had to be cleared, I figured the odds of two gaps over the sensors would be pretty rare. Do note that my sensors were (are) Radio Shack light sensors (...) (24 years ago, 15-Aug-00, to lugnet.trains)
