This series includes station maps, maps of the railway line, plans for bridges, drawings of station houses, and townsite plats. The railway originally had twenty-two categories of maps, but only six are included in the papers. These are 1. Station maps, 2. Trusses and bridges, 4. Moscow & Eastern, 9. Trestles, 10. WI&M standard plans, and 18. Townsite plats. There are also four unnumbered maps. The smaller plans have been placed in a file box (440) the larger one are in a large plastic bag (44). In the list of maps and blueprints, an asterisk preceding the number indicated that the print is in the bag.
