I have all of the Steam Powered Video RR Atlases of the states covering CB&Q and the California Zephyr.
I have highlighted the lines for CB&Q, C&S, FW&D, Wabash, Southern, D&RGW, & WP.
I take the appropriate Atlases with me when ever I rail fan.
These Atlases show current & abandoned rail lines as well as current & past ownership.
