Pennsylvania Station (normally abbreviated Penn Station) is a label first applied by the Pennsylvania Railroad (PRR) to several of its grand passenger terminals.

The 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.

Grand Central Terminal (GCT, often still called Grand Central Station) is a terminal rail station at 15 Vanderbilt Avenue (42nd Street and Park Avenue) in Midtown Manhattan in New York City.
Built by the New York Central Railroad (for which it was named) in the heyday of American long-distance passenger trains, it is the largest train station in the world by number of platforms: 44, with 67 tracks along them.

They are on two underground levels, with 41 tracks on the upper level and 26 on the lower.
