Ha! I hear what you're saying, Norm.
Standards are hinted at from the earliest days, in photos and documents, but adherence to a given set of standards seems to change and also to be concentrated in certain sections of the line, not across the entire railroad. This all is likely tied to specific contractors at different times between 1879 and 1883. Of course each change of management and ownership after that brought new ideas; mix those over 60 years and things look pretty mixed up.
One example that comes to mind are railroad structures in the string of towns on the west slope between Alpine Tunnel and Gunnison built during initial construction. From Woodstock to Quartz to Pitkin to Ohio City to Parlins, when they had them, the original bunk or telegraph houses, the section houses, the water tanks and tool sheds were all of not just near-identical dimension (per B&B books, inventories and maps) but are nearly identical to the eye, where we have pictures. I know that dimensions will vary with construction but the similarity of each building type visually added into the documented dimensions over time points to a standard design for each type. Look at Quartz' section house compared to the one at Ohio City...same. The bunk house at Ohio City and the telegraph office at the Tunnel (the ex-Woodstock bunk house)...same.
Maybe not quite as rigid, but still looking to have used standard plans, we have Hancock, St Elmo and Alpine (later Fisher) station structures, and also the water tanks at Alpine (Fisher) and Hancock, and things point to the Lady Murphy tank being similar to those, too.
Of course all this initial "company look" went to hell over the years.
