The Pennsylvania Railroad (PRR) was established in 1846, later than the Philadelphia to Reading line. The PRR originally developed going west – connecting Harrisburg and Johnstown to Pittsburgh. Later, in 1857, it expanded its northeast corridor from Philadelphia. By the late 19th century it was the world’s largest business enterprise and a world-class model for technical innovation. This is where the original PRR station was located.
