WiringI will make up a temporary control panel which will eventually be on the board for the fiddle yard.
Operation is DC using an old but little used Gaugemaster D controller. This offers two separately controlled track feeds and a 16v source. My layout has seven isolated rail lengths and this is known as Board 2, with Board 1 (the fiddle yard) to the left, and Board 3 (a possible extension) to the right

I will wire these so that there are five separate sections, with each one controlled individually via double-pole double-throw centre off switches. That may sound overkill for a small layout but it will enable me to display locos as well as test them. The codes I am using are:

The control panel will then look like this, about 6x12cm, the square blocks where the DPDT switches will be, and numbers 1-7 referring to the rail lengths, and A & B the point motors.

Note I have omitted the wires from controller 2 to the switches but they will mirror those from controller 1.The Turnout Motor Feed has to be wired differently, and I will use a 9v battery to power them:

I will also connect wires to D-connectors for the control panel, and connectors between boards.
I know everyone is busy preparing for Scaleforum, but I would welcome comments and thoughts on alternatives, especially if anyone is screaming in their mind: "don't do it like that"!
