Moynihan Train Hall is an expansion of Pennsylvania (Penn) Station, New York City’s main intercity and commuter rail station. Built across 8th Avenue from Penn Station in the city's former main post office building, the James A. Farley Building, the annex provides new access to most of Penn Station's platforms for Amtrak and Long Island RailRoad passengers. Named after Senator Daniel Patrick Moynihan, the new 255,000 square foot (23,700 m2) hall provides ticketing, baggage, and customer service facilities, plus a large 320-seat customer waiting area for the thousands of daily passengers. AtlasIED technology was installed during the hall’s construction to deliver audio and emergency communications to employees and passengers.
The train hall, which opened in 2021 after a four-year construction project, was built to alleviate congestion in Penn Station. Penn Station and Moynihan Train Hall serve more than 700,000 passengers daily, making it the busiest transportation facility in the Western Hemisphere, serving more passengers than LaGuardia, John F. Kennedy and Newark International Airports combined. The $1.6 billion renovation restored the Beaux-Arts Farley Building, a designated landmark, and added a central atrium with a glass roof. A remarkable feat of engineering and design, the station was selected as a finalist for the venerable 2021 Prix Versailles award in the passenger stations category.
