I thought DCC was supposed to make wiring simpler. You know, just hook up two wires and you're set. 
OK, I never really did believe that, but why such complicated wiring?

DCC without feedback and signaling is cake. Signaling requires 1 wire for each LED plus a common for the group (3-4 wires per signal). Location sensors require 2 wires per sensor. A turnout controller requires 3 wires per turnout. Now, have 30 sensors and 30 signals and 20 or 30 turnouts and you have a lot of wires. Add to that a few lights scattered around and things get really complicated when wiring. The scheme I use is based on Cat 5 and 110 block standard wiring schemes so it makes it very easy to run all those wires in a way that can be managed and maintained. I use 24 gauge for everything but the DCC bus.
