Control a 3-light Colour Light Signal automatically with this and the Automatic Signal Control pack (AUTO-1).
A magnet fitted to each locomotive will operate a track mounted switch which in turn operates two time delay switches. As the locomotive passes a signal the time delay switches changes the signal from green to amber then after a short delay to red and then after another short delay the signal reverts back to green.
This pack includes a Time Delay Switch and cables to connect to the other Time Delay Switch included in the Automatic Signal Control pack (AUTO-1)
