Having finished isolating track the task was now to start powering the trackwork. There are going to be three independent DC systems:
Powering the sections.
Powering the turnouts.
Powering any lights and accessories around the layout.
Before starting wiring I decided to clean up some of the track. I polished down many of the solder joints but importantly I filled in the gaps in the PCB ties and the gaps in the rails in the crossovers.
I didn’t get as far as I hoped today but I made a start. The overall wiring concept for the track power simply involves adding two main buses that will separately power the two sections. I need to secure the buses to the board then run wires down to the tracks.
Here’s a little diagram I put together to help me understand what I have to do.
I want to suspend the bus below the board. I don’t want it held tightly against it. I was thinking of using ceiling clamps for curtains but the cost is more or less the same as having Shapeways make them for me. Therefore I did a quick design for a clamp and they will cost around $5 each to print up. The clamps will hold each bus away from the board which helps with maintenance.
