"Map Showing the Routes of Trans-Continental Railways as Explored and Constructed", U.S. War Department

This very interesting map has no attribution to maker or publisher. Filled with detail, it extends from the Mississippi River to the Pacific coast. It primarily focuses on the extensive railroad network that existed in 1883. Red overprinting is used to delineate the routes explored by the Pacific Railroad Survey of 1853-4. Notation at lower right says "Red lines exhibit routes for a Pacific Railroad, as shown by a map compiled to accompany the report of the Hon. Jefferson Davis, Sec. of War, in the office of Pacific Railroad Surveys. 1855."
