Backdating Sherman Hill

Hello All,
As I'm sure many people here are as well, I am a big American Steam fan. I am going to be backdating Sherman Hill to before 1953 for personal use and was wondering if anyone knows of some good sources I could use to base my work on. I am not going to be going for 100% accuracy, but I do want to make it feel like the steam era. Anything about what Laramie and Cheyenne might have looked like during the 40s and early 50s would be appropriate. I am going to probably do this work in scenario form (like the stephan's pass backdating) so it will be possible to share.
I have found this site which will atleast help me get rid of some of the track. But I am unsure of what the roadways were like in that era.
