I have completed scanning all 100' of the 1927 profile maps of the SVRy. Are you interested in having a few CD's for sale in the gift shop/depot?
Also, I've burned a copy for the depot computer, all you have to do is come and get it! This is a great reference, and much more convenient to handle. I scanned at 150 dpi, so all the writing is very clear. It shows every switch, siding, most RR structures, crossings, grades, etc. in high detail, from Baker, all the way to Prarie City.
