The Largest Subway Layout in North Dakota
Cabling is monted on the ‘sub fascia’ of the layout. All wires are therefore accessable without having to go under the table. The finished fascia is mounted over the top of wiring chase way.Cables like many other aspects of the layout is used second-hand. The wires shown on the left came from an old 1920s vintage pipe organ removed from the church during the renovations in 2000. The wire has no rubber or plastic insulation. The insulation is made of waxed string. The cable as salvaged (right) had six bundles of eleven wires each. They were not marked, and each line had to be tested at each end.Once this cable was used up, I purchased 100’ of 25 pair cat 3 telephone type cable. That is 50 nicely colored wires per cable.Far left is termination of the layout cables at the control panel The information labels mark the position of nails which are used as binding posts which are cheap in an application for which I cannot afford terminal strips or other kinds of connectors. I used 14 ga / 4 conductor speaker cable for the power bus on the railroad. The green conductor is a ‘hard ground’ grounded to the building power system. A floating common would have stray voltages that would upset the operation of the railroad. The black conductor is third rail (track) power, White is +16v dc power to the signals, relays and track detectors. The red conductor is ‘hotel-power’ +12 v dc from a used computer power supply. It is used for all lighting applications around the layout.
