Something I've never been able to find was original floor plans for D&RG depots and/or depot floor plans for other road names. I'd be mostly interested in the original layout for the Durango depot, maybe the RGS Rico depot as well.
I've been inside the Durango depot enough times to probably be able to draw the current floorplan of today from memory, but the two sides where the D&S giftshops now are and the second floor for office space I'm fairly confident don't represent anything you would've seen prior to 1968 as they've been remodeled to suit different needs today.
Thanks for any help.
