How could I forget about shorts?

How could I forget about shorts?

Well I did. In my defense it has been two years since I last had to spend hours looking for a short, but still! As you can guess I went ahead and wired up all my feeders to the BUS wires and then surprise surprise it no work. Still lacking a memory of shorts I unwired all the feeders and still had a short. After some time with a continuity tester I remembered that the frogs on all Peco Electrofrog turnouts needed to be gapped or insulated. I had done some, but not all. Anyway after using my Dremel cutting wheel to make the missing gaps, all the shorts went away and I can now start again. This time I will test with my RRamp meter after every connection that everything is still OK.

At least I have finished wiring the 40 turnouts to the front of the layout. Now all I have to do is connect a whole load of accessory decoders and design the control panel for the switches and lights. It is already built. Then comes the fun part — coding a NCE Mini Panel.

But first I have to get the track wiring organised and test run some Locos. That should be fun, I hope.

And the beat goes on . . .

Donkey deep into wiring. I have 40 turnouts installed on just modules 1 & 1a and at least as many blocks requiring feeders and NCE BD-20 block detectors. Once all the block wiring and the accessory decoders are installed I plan to create a control panel with a diagram of the tracks and to install toggle switches and push-buttons to control the routes. The main line routes are going to be set using a NCE Mini Panel. For mainly economic reasons the industrial sidings, that do not require signalling, will use a central CDU (Capacitor Discharge Unit) and a diode matrix if necessary.

The following photos give an indication of where I am at with my wiring. Once finished I can start on building the industry kits and wiring up the temporary oval of track to enable test running and switching operations.

Mainly Kato Track laid on Module 1a for the freight main line and industries on the right. Main passenger line with scissors crossover is on the left.
Module 1 – the 7 track Joint Line return loop and staging tracks. Tracks for D&RGW Burnham Yard & Shops are in the center. Start of the  PSC Arapahoe Power Station on the left
After attaching 2 pulleys to form an old fashioned “block & tackle” system Modules 1 & 1a were lifted into the air so that work could start on the wiring without having to work under the layout.
