"...Even if it's as Big as a Mountain!"
The first railroad to cross the Allegheny Mountains, the Allegheny Portage Railroad was the final piece of the Pennsylvania Main Line Canal. "The Portage" opened in 1834, marking the first time that there was one, direct route between Philadelphia and Pittsburgh. All things to all people, it served merchants, passengers, slaves in pursuit of freedom, and soldiers from the Mexican War.
