Bakersfield & Ventura Model Railroad

I was cleaning my garage the other day and pulled out a 30x60 inch layout I started some years back in HOn30, but abandoned pretty quickly. The trains were just too small for me, and there wasn't a lot of equipment available -- there's no equivalent of Bachmann's relatively cheap and plentiful ready-to-run On30 cars and locomotives, and only a few kits. I'm kind of taking this as a sign from the fates. The overall size of the old, partly built layout is in the upper range of what I was thinking about doing in On30. The curve of N scale track at the left end in the photo is 12 inch radius, and the right end is 13 inches, both in the range of what I was considering. The rest of the track plan doesn't translate so well -- the plan drawn on the board has a passing siding on the front side that would have been short in HOn30 and would have been all but useless in On30. The upper level branchline track has a 9 inch curve, which is probably too tight for anything but an 0-
