An expanded Penn Station West End Concourse, the first phase of the transformational redesign of America’s busiest transit hub, opened in June 2017. The new, state-of-the-art concourse increases passenger flow and streamlines train operations by doubling the length and width of the original concourse, providing new stairways to nine of Penn Station’s eleven train platforms, and adding an additional passenger elevator on each platform for comfort and increased ADA accessibility.
