Just finished up re-routing the ground wires. Since I was dropping down to 14 gauge wire at first I was going to use a common ground for everything to hopefully save on wire runs but as I started running wire I decided on two ground circuits. I have my three track power supplies on one common ground and the ITADS, ACC, and Turnouts on another ground circuit.
Next week I will start re-routing power. This will be fairly straight forward just as with the ground with the following exceptions:
1. Power for each of the three power districts (track power) must be electrically isolated from one another.
2. Power district 2 will contain spurs with on/off switches that must be wired from the control board.
3. Power for the ITADS and turnouts could be ganged together but since I have separate transformers for these I will keep the power lines isolated.
4. All accessories are powered by a 12VDC supply so this power for this circuit must be kept separate.
Sand mats came in the the two yards. Once I get the wiring done I will lay down the mats and start placing track.
