This article is about the original Penn Station that existed in New York City between 1910 and 1963.Pennsylvania Station was a historic railroad station in New York City. The station occupied 3.2 ha, bounded by Seventh and Eighth Avenues and 31st and 33rd Streets in Midtown Manhattan. It was designed by McKim, Mead, and White and completed in 1910. The original Pennsylvania Station head house and train shed were considered a masterpiece of the Beaux-Arts style and one of the great architectural works of New York City. As the terminal shared its name with several stations in other cities, it was sometimes called New York Pennsylvania Station, or Penn Station for short. Penn Station maintained its architectural grandeur until World War II when rail usage started to decline. In the 1950s, the Pennsylvania Railroad sold the air rights to the property and downsized the railroad station. The above ground head house and train shed of the station were demolished and replaced by Madison Square Garden and Pennsylvania Plaza between 1963 and 1969. The destruction of Pennsylvania Station galvanized support for architectural preservation across the United States, leading to the advent of modern historical preservation. The below-ground concourses and waiting areas were heavily renovated during this time. However, the platforms at the station's lowest level were not significantly modified, and evidence of the original station still exists at platform level.
