Reply to "Wire Gauge"

I have no quarrel with the ohms/foot figures above, but to me it always has seemed that voltage drop on a layout exceeds what the tables say it should be.

Then there is the effect on command control signal strength.

When I first built my layout, in the early 90s, I used 14 gauge, except for a 4 track storage yard, with 3 blocks per track. To save money/time, I used 18-gauge multi-conductor cable. When I added DCS, the signal strength on the rest of the layout was great, but useless on these 4 tracks. I rewired with 14-gauge, and got excellent signal strength.
