By the way, I was serious when I said your narrow gauge layouts got me hooked to narrow gauge. After an extensive N scale collection of NYC stuff, including brass, now I took advantage of Trainworld's specials on some of Bachmann's On30 stuff. I know it's not 100% proto for common narrow gauge in the US, but I'll make up my own railroad. Got myself the 0-4-0 Porter, 0-4-2 Porter, 4-4-0, and 2-6-6-2
Each one was $59-99 each on their blowout sale. Over $1k worth of engines for a few hundred. Now to start scratch building some rolling stock (and finish my N scale layout!)
