Kato HO UniTrack 123mm 4 7/8″ Automatic 3 Color Signal (1 pc) 2-601

Description

Available for the first time from Kato in HO, a 3 – Color signal system for your HO UNITRACK Layout! Fully compatible with both Analog (DC) and DCC based systems, this signal will turn red when a train runs over the built-in track sensor, eventually turning yellow and then switching back to green after a period of time has passed once the train leaves the sensor. For those operating DCC, a small switch on the underside of the track can be used to switch the signal over to AC mode, where it will continue to function exactly as it does in Analog mode. This item uses item # 24-844 Automatic Signal Power Supply
