The DCC buss is the heart of the layout

This is the power for the two power districts of the Wildcat Valley RR. I chose the Digitrax 20 Amp power supply to get good, clean, consistent power for the DCS-210 command station and the DB-150 operating as a booster for the DCC buss.

The WVR uses a Digitrax PR3 to make the connection from Loconet to the JMRI computer. There is a UR-93 duplex transmitter connected as well for the wireless DT500D and the DT6D throttles. I replaced the previously used UR-92 which was not compatible with the newer throttles as they came from the factory, I had to send the throttles to Digitrax for adjustment to get them to work with the older transmitter. The newer transmitter has a stronger signal and will not require any throttle adjustments.

The DCC buss which carries power and control signals to the track and the various accessory decoders used on the WVR is 12-gauge stranded wire that is connected serially to terminal blocks located around the layout. These terminal blocks are used to feed the track using an 18-gauge sub buss connected to each section of track using 22-gauge feeders. I do not trust slide-on track connectors to provide a good connection. All buss wire connections are soldered and sealed with heat shrink tubing. Every section of track and turnout has a feeder wire soldered to it to maintain a good connection. I have never found it necessary to solder the track joints.
