Pennsylvania Station (normally abbreviated Penn Station) is a name applied by the Pennsylvania Railroad (PRR) to several of its grand passenger terminals. In the early 20th century different railroad companies typically used different stations, especially in major cities or towns, so the station usually took the name of the company. (If various railroads combined to use the same depot, the place often took the name Union station.)
The PRR station in Cincinnati, Ohio at Pearl and Butler Streets, built in 1880, was named Pennsylvania Station. It was supplanted with the opening of Cincinnati Union Terminal in 1933.
Harrisburg, Pennsylvania's Union Station was also known as Penn Station. It was built in 1887 and rebuilt in 1905. It was shared by Reading Railroad, Northern Central Railway, and the Cumberland Valley Railroad, until the Reading Railroad built a separate station in Harrisburg. Today it has the name Harrisburg Transportation Center and serves Amtrak's Keystone Service and Pennsylvanian intercity lines, along with Greyhound, Trailways, and local bus services.
New York City's Penn Station opened September 8, 1910 for Long Island Rail Road trains via the new tunnel under the East River. Pennsylvania Railroad trains began using it November 27, supplementing and eventually replacing the old New York City-area terminal across the Hudson River at Exchange Place in Jersey City. The name was adopted by the PRR on March 1, 1909. The opening of the Hell Gate Bridge on April 1, 1917 brought New York, New Haven and Hartford Railroad intercity trains into Penn Station. The station now lies along Amtrak's Northeast Corridor and Empire Corridor, and also serves New Jersey Transit and Long Island Rail Road commuter trains.
