With double ended yards, turnouts can be controlled in pairs as long as there is sufficient power from the controller for it. I am most likely going to use the Digitrax DS64 stationary decoder to control the routes and turnouts for this particular project and have tested it and know that it's output can handle it.
I used 22 gauge stranded wire for this part. A different color wire twisted with a black wire is used for each pair of turnouts. I normally like to use Euro type terminal strips for my under layout wiring but as I had so many of the standard screw type in a box I decided to use these for the turnout control wiring.
The 22 gauge wire can either be tinned and bent around the screws or a lug can be crimped on, both ways are shown here.
After the yard is installed, the connections to the controller will be made from this terminal strip.
At this point all of the track and wiring that can be done with the module on it's edge are done and it's time to install it in it's place in the layout.
