There has been a lot of discussion on various DCC chat lists and users groups regarding this subject, WIRING.  There generally two type of wiring you will be doing with your DCC System.

1. Power Buss Wiring: A power buss reduces the electrical resistance in your rails and improves the communications between the Command Station and the locomotive decoder.
2. Track Wiring: This is generally the wire between the track and the Power Buss.
3. Command Station/Power Booster Wiring: This is the wire from the power supply and the Command Station/Power Booster.
4. LocoNet® Wiring: Loconet wiring if between the Command Station/Power Booster and remote locations for plugging in Throttles and other LocoNet devices (i.e. Fast Clock, DS-54 Stationary Decoders, Radio Receiver and UP-1, 2, 3 Ports).

Wire Function	Size/Gage	Stranded	Solid
Power Buss Wire	10 or 12	X
Track Wiring	22 to 24	X	X
Command Station	22 to 24	X
LocoNet®	Flat 6 conductor		X

(Wire Gage: The larger the number the smaller the wire)

Another of the more frequently asked questions is "Do I need a Power Buss", generally the answer is YES.  If your locomotive will be traveling more then 20' to 30' away from the Command Station you will need a power buss.  What you will notice is your train/locomotive will slows down when gets about 20 to 30' away from the Command Station.  If this happens you need to add a Buss.
