York City Manhattan's Penn Station opened September 8, 1910, for Long Island Rail Road trains by means of 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. New York City Subway stations named for the intercity terminal include 34th Street–Penn Station (IND Eighth Avenue Line) and 34th Street–Penn Station (IRT Broadway–Seventh Avenue Line). 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. Notable examples include Philadelphia's Pennsylvania Station–30th Street, which became Penn Central Station–30th Street, Baltimore, Trenton and Newark Pennsylvania stations, 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 exception to this was Pennsylvania Station in New York City, 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. Further reading 370pp External links References Penn Central Transportation
