Rail200 - "First fix" wiring

This morning's job was to attach wires to the tracks. Holes were poked through the foamboard into the holes in the ply below, and wires passed through.


The ends were stripped, bent to a shape that should fit into the web of the rail, and tinned with solder. At the same time, the rails were soldered to the copper-clad strips at the board end.


The wires were then pushed into place and the iron and more solder added, creating a solid joint, but being careful not to dwell with the iron too long to melt the plastic sleepers or foamboard below. 

Underneath, the wires were run back to a terminal block. I've labelled all the holes and the terminal block connections with which wire (for which track section) goes where, it helps in the future when I'll have forgotten what goes where. I used short lengths of wire stapled to the baseboard to hold the wire runs, the ends are twisted together around the bundle of wires. 

And that will be it for now. I'm not sure where I'll put the control panel/switches, the placement of the longitudinal ply support means my preferred location in the fascia isn't going to work. I've not decided if I'll fit point motors, or try manual control - dowels across through the ply sides might work well, but would need point frog switches. In any case, the deadline for entry requires a photo of the layout, and there's no requirement for it to be a working layout anyway. So, given limited time, I'll focus on completing the scenic side and can worry about wiring (along with a fiddle yard, uncoupling magnets, and other operational stuff) later. It's a bit back-to-front for me, as usually I'd make sure everything is working well before moving on with scenic treatment, but needs must!
