Rich,
I'd enjoy seeing your input on this project. Era is always an issue. We have been moving towards as-built on recent projects as of late, but it really is about what era will generate the most interest. I have lots of ATSF books now so if you want to point out pages from certain books I should be looking at or past issues of the Warbonnet, that would be really helpful. I am a member of the Santa Fe Railway Historical & Modeling Society so I have about 18 months of back issues.
