Here is a size comparison between my Bachmann Shay (Chimney Rock Stone & Gravel No. 2) and the Keystone Locomotive Works Shay (CRS&G No. 1) which didn't run worth beans, and because of which I scratchbuilt Chimney Rock Quarry No. 3. No. 3 is 2 scale feet shorter than the Keystone Shay. I couldn't take a photo of Nos. 2 and 3 together because the scratchbuilt one is currently on my workbench for some cab glass replacement.
