TTSS4T Sensor Signal (Theatre Indicator) 3 Aspect Distant MC-Active Coal is black and smallerWith the use of the Sensor Signal developed by Train Tech you can easily add automatic signalling into your layout in seconds.

As soon as the locomotive has passed the sensor the signal changes to yellow and will stay yellow for about seven seconds to let the train clear the block. It then reverts back to green. If
