and not loose the DCC/Sound signal along the way....
Twisting the DCC power bus as it follows the track is the right method but be sure to add a snubber/filter to the DCC bus at the far end away from the track power booster. That helps greatly to minimize signal interference due to long DCC bus feed wires. 100-150 Ohms (not critical), 1/2 watt in series with a 0.1 uFD, 50V (or so) non-polarized ceramic capacitor are the right values to use. 12 AWG is probably overkill. 14 or 16 will work equally as well for N scale. You could also add a second snubber ~1/2 way down the bus if there is interference.
