The CO RR Museum Library has binders associated with their CO ICC maps, with detailed inventories of railroad structures including depot drawings with rough floor plans. The Durango depot floor plan circa 1920ish is almost certainly in the Golden library collection.
My books & magazines are boxed up at the moment, but I vaguely recall Harry Brunk writing in the
Gazette about using ICC maps/inventories as a research resource, long before the CRRM made them available. I think he retrieved the materials from the Library of Congress, so that could be an option for non-Colorado ICC materials that CRRM doesn't have.
