Unitrack Automatic 3 Colour Signal SX LH Straight Track

The automatic colour light signal for N Gauge UNITRACK is making a renewed debut with a completely reengineered structure to enhance versatility. With a redesigned power connection system and track length, it can now be installed more easily! The main signal unit features a 64mm straight track, offering greater flexibility in layout placement (e.g. tight curves, turnouts, etc.) compared to previous models. By combining it with the included extension track, it can also function as a 124mm straight track, just like the earlier products. When combined with the two included 30mm straight track pieces, it forms the equivalent length of a 124mm straight track, making it compatible with previous products as well as with the Elevated Signal Bridge (Item 20-421) designed for 124mm tracks. Features: - The system uses a reliable rail contact sensor that detects passing trains via wheel flange contact, ensuring accurate operation. - Automatically detects the layout’s power system (Analogue/DCC). - By using the 22-081 Accessory Power Supply (plus the 22-082 KATO Power Supply 12V) to power the signal, it is compatible with DCC layouts as well. Note: In DCC layouts, the signal stays green when no train is present, regardless of the direction of travel. Therefore, if a train is moving against the signal’s direction, the 24-848 Stop Signal Button must be used to force the signal to red.
