Something different from my ususal train videos. This is a circuit that I built for my HO scale train layout. It simulates a real working block signal with four aspects; clear, approach, advance approach, and stop and proceed. It runs on a timer so the signal will cycle through all of the aspects. In normal practice it would not run on a timer, the position of trains within blocks preceeding the signal would give the appropriate aspects. ENJOY!
