This map is nearly identical to a slightly earlier government-issued map from 1847 which Modelski describes as "one of the earliest small-scale government maps to show a railroad network" (Modelski #11). It covers the eastern United States, eastern Mexico, Central America, and the Greater Antilles and depicts both completed and proposed railroads within the United States. In addition to railroads, shipping routes radiate from Pensacola to various destinations including Galveston, Vera Cruz, Chagres and Havana demonstrating that city's favorable position to important ports. Printed on two sheets and joined. The map was issued to accompany a report by Sidney Breese "for granting Land to the State of Illinois to aide in the completion of her Rail Roads."
