Pennsylvania Station
Pennsylvania Station (normally abbreviated Penn Station) is a name applied by the Pennsylvania Railroad (PRR) to several of its grand passenger terminals. Several are still in active use by Amtrak and other transportation services; others have been demolished. In the early 20th century, different railroad companies typically built separate stations, especially in major cities or towns, so the stations usually took the name of the companies. If various railroads cooperated to use the same station, the combined depot often took the name Union Station. Baltimore. Baltimore, Maryland's Union Station was renamed Penn Station on August 1, 1928 . Amtrak Northeast Corridor intercity service and MARC commuter service still operate through the station; the station is also served by a spur of the Baltimore Light Rail. Cincinnati. 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. Cleveland. Cleveland, Ohio's old Lakefront Union Depot was renamed Penn Station on April 28, 1946. It was last used September 27, 1953, and service was cut back the next day to Euclid Avenue. Harrisburg. 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. Jersey City. Pennsylvania Railroad Station in Jersey City, New Jersey, opened in 1834, was the terminus for New York City market trains prior to the construction of the North River Tunnels under the Hudson River and the  Pennsylvania Station in New York City. In the 1920s, the station took on the name "Exchange Place," in contrast to the main station across the Hudson River. Train service to the station ended in November 1961 and demolition of the complex was completed in 1963. Newark. Newark, New Jersey's Penn Station opened in 1935, replacing a smaller structure. It now serves NJ Transit trains, buses and Newark Light Rail, Amtrak Northeast Corridor and other intercity trains, PATH trains to Jersey City/Lower Manhattan and Greyhound buses. New York. New York City's Penn Station opened September 8, 1910, for  Long Island Rail Road trains via the new tunnel under the East River. Serving more than 600,000 commuter rail and Amtrak passengers a day, it is the busiest passenger transportation hub in the Western Hemisphere. 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 services Amtrak's Northeast Corridor and Empire Corridor, as well as New Jersey Transit and Long Island Rail Road commuter trains. Philadelphia. Philadelphia, Pennsylvania's 30th Street  Station was named Pennsylvania Station when the upper (commuter) level opened on September 28, 1930. It was renamed Pennsylvania Station–30th Street on April 26, 1933, soon after the lower (intercity) level opened on March 12. Intercity PRR trains used that station, while commuter trains continued east to terminate at Suburban Station. The station is still used by Amtrak intercity service, New Jersey Transit Atlantic City service, and SEPTA commuter service. Pittsburgh. Pittsburgh, Pennsylvania's Union Station was renamed Penn Station on December 17, 1912. It is still used by Amtrak intercity service. Penn Central Station. With the 1968 merger of  the PRR into Penn Central, several of the Pennsylvania Stations were renamed on June 6 to Penn Central Station. Philadelphia's "Pennsylvania Station-30th Street" became "Penn Central Station-30th Street", while Baltimore's Pennsylvania Station, Michigan Central Station in Detroit, Michigan, New York Central Railroad's (NYC) Buffalo Central Station, and Pittsburgh's Pennsylvania Station became simply "Penn Central Station". The stations in New York City and Newark, New Jersey kept the old name, "Penn Station", the former because Penn Central also operated Grand Central Terminal. PRR stations not named Pennsylvania Station. Other major PRR terminals that never received the Penn  Station name include: Chicago's Union Station, Cincinnati's Union Terminal, and Washington, D.C.'s Union Station. These were all used by other railroads in addition to the PRR.
