Wiring Hornby Turnouts for DCC

If you're looking to add DCC (Digital Command Control) to your Hornby model railway, one of the first things you'll need to do is wire your turnouts. This can be a daunting task, but it's not as difficult as it seems. In this article, we'll walk you through the process of wiring Hornby turnouts for DCC, step-by-step.

Tools and materials

To wire your Hornby turnouts for DCC, you'll need the following tools and materials: * A DCC decoder * A pair of needle-nose pliers * A soldering iron and solder * A multimeter * A length of wire * A piece of heat shrink tubing

Wiring the turnouts

The first step is to wire the turnouts to the DCC decoder. Each turnout has two terminals: a common terminal and a throw terminal. The common terminal is connected to the negative rail, and the throw terminal is connected to the DCC decoder. To wire the turnouts, you'll need to connect the common terminal to the negative rail and the throw terminal to the DCC decoder. You can do this by soldering a piece of wire between the two terminals. Once you've wired the turnouts to the DCC decoder, you'll need to test them to make sure they're working properly. To do this, you can use a multimeter to check the resistance between the common terminal and the throw terminal. The resistance should be zero ohms.

Wiring the points

The next step is to wire the points. The points are the parts of the turnout that actually divert the train tracks. Each point has two terminals: a fixed terminal and a moveable terminal. The fixed terminal is connected to the common terminal of the turnout, and the moveable terminal is connected to the throw terminal of the turnout. To wire the points, you'll need to connect the fixed terminal to the common terminal of the turnout and the moveable terminal to the throw terminal of the turnout. You can do this by soldering a piece of wire between the two terminals. Once you've wired the points, you'll need to test them to make sure they're working properly. To do this, you can use a multimeter to check the resistance between the fixed terminal and the moveable terminal. The resistance should be zero ohms.

Testing the turnouts

Once you've wired the turnouts and the points, you'll need to test them to make sure they're working properly. To do this, you can use a DCC locomotive to drive over the turnouts. The locomotive should be able to switch tracks smoothly when it drives over the turnouts. If the locomotive is not able to switch tracks smoothly, you may need to adjust the wiring. You can do this by loosening the screws on the turnouts and moving the points until the locomotive is able to switch tracks smoothly.

Wiring Hornby turnouts for DCC is a relatively simple process, but it's important to make sure that you do it correctly. If you're not comfortable with electrical wiring, you may want to consider hiring a professional to do the job for you.
