Google "HOn30" or "HOn30 drawings". For your purposes, photos will do as
well as drawings, I think. Anyhow, there was a fair amount of variation
in dimensions, so anything you build that looks like the photos will do
30" (2-1/2ft) gauge was rare compared to 2ft and 3ft, but the dimensions
of the rolling stock didn't vary all that much. Several makers made the
same engine for several gauges (Porter was famous for doing this). So
googling on "HOn3" will also yield useful pictures and some drawings.
Generally, 2ft gauge rolling stock was 5 to 6ft wide. Length depended on
type and load, with larger freight cars 20-30ft long. The longer
(passenger) cars were up to 40ft long.
The proportions of cabs, doors, windows, and appliances mounted on the
boiler are the key features to achieving the narrow gauge look. A fairly
easy conversion is to cut the cab off the Minitrix steam loco, and build
one that will fit a six-foot tall HO person, ie, make it about 1 inch
high floor to roof, about 7/8" wide, and about as long. Strip off the
domes and smoke stack, etc, and replace with ones about 50% larger. Make
a new end beams to the same dimensions as the cab width.
Further to your request. I did a bit of googling, and found this site.
The drawings aren't "construction quality", but they should give lots of
useful ideas and plenty of inspiration!
Thank you very much for the information and the link. There is a
great amount of information to get me started. I had started to
Google as well but did not get results like yours. Different key
