US architecture firm SOM has released new images of the proposed Moynihan Train Hall expansion at New York?s Pennsylvania Station, which would turn an old post office into a grand waiting room for Amtrak.
The 486,000-square-foot (45,000-square-metres) hall would feature a curved glass roof set inside the 1903 Farley Post Office building, originally designed by McKim, Mead & White.

The long-stalled project was recently revived by New York Governor Andrew Cuomo, as a part of the larger renovation of Pennsylvania Station (Penn Station), which is located across the street from the Farley Post Office Building.
The Moynihan Train Hall renovation would accommodate passengers of the national railway, Amtrak, alleviating congestion in the existing station facility.

It would feature four bays of arched glass roofing springing from existing steel trusses.
Behind the waiting room, a second area, also featuring a glazed roof, would be converted into a shopping and dining arcade.

The plan also calls for new wheelchair accessible entrances flanking the building's monumental staircases.
A new block-wide pedestrian tunnel would be built under 33rd Street connecting Moynihan with Penn Station.
