Walthers Layout Control System brings you a low-cost solution for easy turnout control for HO, N, Z, S, and O Scale layouts! The system is expandable at any time to grow with your layout, and can be used with DCC- or DC-power (a DCC accessory decoder is integrated into the switch machine). The system uses plug-and-play servo-style wiring with connectors, so no soldering is needed; two styles of cables are available separately to expand your wiring as needed. User-friendly instructions are included with all items, and drilling templates for easy mounting on your layout or fascia are included as appropriate. Using combinations of the system components, which include servo-based slow-motion Switch Machines, Power Distribution Block, LED panel indicator/control pushbutton switches, add-on system cabling, a 2-amp 12V Filtered DC Power Supply and a three-piece drill set, you can easily build a complete control system.
