I couldn't help but notice that those look like 18 gauge wires that are connected to all of the breakers, DCS unit, and other equipment under your table.  Are those carrying the full 16 volt load from your transformers to the bus lines?  (Not criticizing, just trying to learn.)

You're noticing incorrectly.   All the feeds from the transformers to the TIU channels are #16 and they're short runs.  The output of the TIU goes to the terminal blocks next to them, the wiring out to the track is #14.  Current carrying isn't an issue, so I only concern myself with voltage drop at maximum current, that's a little less than 1% for the roughly four feet of #16 wire used.  I can assure you, even running three trains on the mainline, all with smoke, no issues at all with power drops.
