The newer Penn Station. The Farley Post Office across from New York’s Penn Station was designed by the legendary architecture firm of McKim, Mead, and White, just like the original NY Penn Station. As the USPS has transitioned out to neighboring facilities, it is presently transitioning to become the Moynihan Train Hall to enlarge and better serve commuters. An aerial view on December 12, 2018 shows the construction progress on the building from an east to west view.
