Probably not much sought after anymore but August Derleth turned out a beauty in 1948:
The Milwaukee Road - Its First Hundred Years
Being a Derleth fan my entire life when I found out he wrote such a beast I tracked it down. Very interesting history of the initial financing and creation of the road. Derleth did not live to see the total demise and I'm thankful for that. Not many photos.
