@Mannyrock posted:A maximum run of 8 feet of the 18 gauge wire out to a track, would permit almost a 15 ft x 7 ft layout. I'm just a novice, but that's pretty big in my book. :-)
Well, that's only if you put the transformer in the dead center of the room. Also, it would have to be a straight line wire to the track from the transformer stretched out like a clothes line! You'd be amazed how much more wire it actually takes to get to the track from the typical transformer location.
P.S. Mine's not that big a layout, but with my new freight yard it's almost 40 feet long. Big are those basement filling monsters that have several thousand feet of track!
