The SPV Railroad atlases provide a single source of reference to the North American rail network, past and present. They are widely recognized by rail fans, railroad historians, and professionals as the industry standard. Each sheet is drawn to a constant scale of 8 miles to 1 inch for easy distance comparisons with 2 miles to 1 inch enlargements of complex areas. All extant rail lines are shown together with stations, junctions, yards, principle bridges and tunnels. Former lines, now abandoned, are also shown as well as ownership, current and past, and trackage rights. An index of stations is included. The atlases are printed on quality art paper with softcover and stitch bound for ease of use at trackside, each volume provides an average of 80 maps.
