Expanding the train station, the busiest in the nation, is a pressing issue because construction has just begun on a $16 billion pair of rail tunnels under the Hudson River, the centerpieces of a project known as Gateway, which would double the current cross-Hudson capacity.

The latest plan includes returning to the train station to its pre-demolition Beaux Arts style amid President Trump's classical architecture mandate.

"Grand Penn" features a public space the size of Bryant Park, a train hall inspired by the original Penn Station, and the relocation of MSG across the street.
