I have in hand a "foobie" roadname version of a N&W Y6b, and I want to convert it to a GN prototype (or possibly NP). I am curious as to thoughts on what GN 2-8-8-2 or 2-8-8-0 is pretty close to the same dimensions, wheel diameters, etc. of a Y6b. This one has kind of an unfortunate glacier green attempt for a paint job. Adam
http://www.steamlocomotive.com/chesapeake/?page=nw Y6b: 57" drivers, 15'9" wheelbase each set, 58' overall engine wheelbase, 39x32/25x32 cylinders. Can't say how accurate the model's dimensions are. http://www.steamlocomotive.com/chesapeake/?page=gn Both classes are 63"-drivered simples, so they don't have the different-size cylinders of the Y6. Their overall weight is closer, but that's about all. http://www.steamlocomotive.com/2-8-8-0/?page=gn Even these are 63"-drivered, while B&O and KCS 2-8-8-0s were 57", as I remember. The rebuilt GN engines approach the size of the 2-8-8-2, but then they're no longer compounds so the cylinders won't work for them. The mechanism is probably a better fit for an NP engine.
