This long and uncommon strip map of the Pennsylvania Railroad was one of the first maps to show the entire line from Philadelphia to Pittsburgh. It was reached in 1852 using the Portage Railroad, and in 1854 using the Horseshoe Curve and the Gallitzin Tunnel. The map was published by P. S. Duval & Co's Steam Lith. Press, Philadelphia in "Guide for the Pennsylvania Railroad with an Extensive Map; including the Entire Route, with All Its Windings, Objects of Interest, and Information Useful to the Traveler." The Pennsylvania Railroad grew to be the largest railroad in the United States.
