The Moynihan Station Development Corporation, a subsidiary of Empire State Development, has overseen the construction of the Moynihan Train Hall, a world-class transportation hub for the 21st century. The Train Hall project was completed on-schedule and opened to the public on January 1, 2021. The historic James A. Farley Post Office Building’s redevelopment into the Moynihan Train Hall created a new 255,000-square-foot Train Hall providing full service and amenities to all Long Island Rail Road and Amtrak passengers, increased total concourse floor space in the Pennsylvania Station-Farley Complex by more than 50 percent, and dramatically expanded circulation and accessibility to the existing train platforms running below it. The redeveloped Farley Building also houses 700,000 square feet of new commercial, retail and dining space within the mixed-use facility and has created an iconic civic space for Manhattan's West Side. 

The Moynihan Train Hall is part of New York State’s transformation of the Pennsylvania Station-Farley Complex to dramatically modernize, upgrade and redesign America's busiest transit hub into a world-class facility. The complex also includes a comprehensive redesign of the LIRR's existing 33rd Street concourse at the current Penn Station facility and an extensive renovation to the adjacent Seventh and Eighth Avenue subway stations.
