A significant revision has occurred in the design of Moynihan Station, the long-planned extension of Pennsylvania Station into the core of the General Post Office (or James A. Farley Building) across Eighth Avenue.
Renderings released last week show that the Moynihan Station Development Corporation, a state agency, has abandoned the proposal put forward 10 years ago by Gov. George E. Pataki for a barrel-vaulted skylight rising nearly 140 feet over a new train hall within the Farley Building.
Instead, the agency proposes to keep the existing roof trusses of the former mail sorting room, which is to become the main train hall.

At their apogee, they would be 90 feet above the floor of the train hall.
They would also recall the vaulted skylights in the concourse of the original Pennsylvania Station, designed by McKim, Mead & White, which opened in 1910 and was demolished in the 1960s. […]
