This Walthers Cornerstone 130' Motorized Turntable in N Scale is a must - have for any model train enthusiast. With an overall diameter of 10 - 3/8' (26.3cm), it's the centerpiece of an N Scale engine terminal. It can turn large locomotives like 4 - 8 - 4 Northerns, 2 - 10 - 2s, and even a 4 - 8 - 8 - 4 Big Boy. Ideal for locomotive terminals, junctions, and anywhere large steam locomotives need turning. It comes with a user - friendly illustrated instruction for easy assembly. The turntable requires a 9 - 15/16' (25.2cm) mounting hole in the layout. It includes a new Cornerstone Turntable Control Box for simple operation and programming on DC or DCC layouts. Features programmable indexing for up to 99 tracks, one - touch 180 - degree bridge rotation, and a simplified LED display. It can be operated from up to four remote locations with additional control boxes. An optional Advanced Control Module allows control with a DCC throttle or serial UART controller. It runs on 12 - 18v AC, 16 - 24v DC power (power supply not included) and has Code 80 rail installed on the bridge.

Using this turntable is easy. First, cut a 9 - 15/16' (25.2cm) mounting hole in your layout as indicated in the template. Then, follow the user - friendly, illustrated instructions to assemble the turntable and install the included Control Box. Connect it to a 12 - 18v AC or 16 - 24v DC power supply (you'll need to provide this). Place your large locomotives on the turntable to turn them around at the end of their runs. For programming, use the new Cornerstone Turntable Control Box. You can set up to 99 different tracks with programmable indexing. For 180 - degree turns, just use the one - touch function. If you want to operate it from multiple locations, buy additional Control Boxes (933 - 2320). And if you prefer to control it with a DCC throttle or serial UART controller, get the optional Cornerstone Advanced Control Module (933 - 2321). When it comes to maintenance, keep the turntable clean and free of debris. Check the moving parts regularly to ensure smooth operation. If you notice any issues, refer back to the instructions or contact customer support.
