Latest work completed:
Command station and power booster wiring
Next work to do:
Running wires and soldering feeder wires to each block and interlocking.
Overview of the Layout
Golden spike is in place (11/23/2025). This spike was the golden spike from my last layout in Maryland.
Wiring for the command station and power boosters. I use the computer power supply for any circuits and
LED lighting (5 VDC) and 12 VDC for incadescent bulbs around the layout.
Track power from the power boosters. The terminals below will be routed to each of the
blocks and interlockings around the layout.
At each of the blocks, the wiring goes through current sensors to detect when I train is present.
The track feeders are on the right which connect to the tracks above.

Track charts showing the location of switches, tunnels, bridges, elevation, grade, and the interlockings and blocks.
Some of the track is not totally accurate due to space, but all the tunnels and bridges are properly located.
Train room dimensions along with the approximate dimensions of the layout.
The size changed a bit as I was laying out the track. The room is approximately 755 sqft.
