Tom started the thread and said he is running DCC and NCE. I have the same setup, and you "lose" 3 volts going through the NCE booster, and you effectively lose an additional 2 or 3 volts through the DCC decoder.
So 15 volts would wind up putting 9 or 10 volts max to the motor. That's just not enought for anything in large scale, realizing it's your MAXIMUM voltage.
I wanted the max voltage, so 27-3 gives 24 volts max to the rails if you turn everything up. The idea was to buy a supply that was not the limitation in the system.
NCE won't go over about 20.1 volts without a factory mod (which was free).
I bought my 27v 11 amp supply from http://www.trcelectronics.com/Meanwell/s-320-27.shtml for $83.
Can't beat it, and it runs 24/7
