The Pennsylvania Railroad was founded in 1846. Commonly referred to as the "Pennsy", the PRR was headquartered in Philadelphia, Pennsylvania.
The PRR was the largest railroad by traffic and revenue in the US throughout its 20th-century existence and was at one time the largest publicly traded corporation in the world. At its peak, it controlled about 10,000 miles of rail line and employed approximately 250,000 workers.
