how likely is an n scale 3 truck shay similar to the bachmann HO product #81909 . Or at least plans made available. They are a fantastic looking locomotive that could have great appeal. I myself am a modeller of the new south wales railways in australia and there was a small shale railway the employed four 3-truck shays very similar to this.
I'm sure there are many fans of shay locomotives worldwide who would relish more than the one engine currently available.

cheers.
