I went to my local train hobby shop today to look at some On30 engines.To me they looked like they weren't much larger than HO.
Actually, in reality they are in fact twice the size of HO scale!
but I agree, they dont look much larger than HO scale..
but the "dont look much larger" thing is perception, not reality.
here is why:
Most On30 trains are models of *small* prototype locomotives and cars. Compared to HO scale, they are larger models of smaller trains.
Most HO trains are models of *Large* prototype locomotives and cars. Compared to On30 scale, they are smaller models of larger trains.
the net result is, they look pretty close in size..HO is smaller models of larger prototype trains, and On30 is larger models of smaller prototype trains.
but if you took the SAME prototype locomotive, say a Prototype 3-foot gauge Forney,
built one in HO scale (HOn3) and one in O scale (On30)..the HO scale model would be half the size of the O scale model..
Take a Bachmann On30 Forney, put an EMD F7 Diesel next to it in the *Same scale* (O-scale)..
The On30 Forney and the O-scale diesel are the same scale, 1:1 to each other. O-scale figures, buildings, automobiles, etc, will "match" them both perfectly,
because both are O-scale...but, catch this: The O scale F-unit will be twice the size of an HO scale F-unit..
Take an HO scale model of the same *prototype* forney as the Bachmann On30 forney,
it will be half the size of the On30 Forney..
