The Pennsylvania Railroad

The Pennsylvania Railroad, also known as the PRR, was one of the largest and most influential railroads in the United States, founded in 1846. It primarily served the eastern U.S., connecting major cities like New York, Philadelphia, and Pittsburgh. The PRR was crucial for freight and passenger transportation, known for innovative engineering and efficient service. It played a key role in economic development, facilitating commerce and mobility. The railroad operated until the 1960s when it merged with other railroads to form Penn Central, marking a significant shift in American rail transportation history.
