|Magnet for use with the Automatic Signal Control Pack. When fitted to each locomotive will operate a track mounted switch which in turn operates a time delay switch. As the locomotive passes a signal the time delay switch changes the signal from green to red and then after a short delay the signal reverts back to green.
This pack includes 5 Magnets
Mount the magnet underneath a locomotive by gluing or double sided tape making sure it will clear any track switches and any rails at points etc, but not too high so it will trigger the switch.
