Gov. Andrew Cuomo unveiled plans on Tuesday for the new station in the historic James A. Farley Post Office, adjacent to Penn Station.

A developer-builder team, including Related Companies, Vornado Realty LP and Skanska AB, have been hired to redevelop the Farley Building into the Moynihan Train Hall, which will create a new 255,000-square-foot train hall to house passenger facilities for the Long Island Rail Road and Amtrak.​

“We’re going to rebuild the Long Island Rail Road concourses first,” Cuomo said in a speech on Tuesday. “It’s a complete redesign of the underground labyrinth. I wanted to say that they reminded me of the catacombs in Penn Station. They said I couldn’t say that, so we said labyrinth instead.”

The joint venture will also create 112,000-square-feet of retail and nearly 588,000 square feet of office space within the Farley Building, the governor’s office said.

“Pennsylvania Station and the Farley Complex across the street—Penn Station gets 650,000 passengers per day,” Cuomo said. “That is double JKF, Newark and LaGuardia Airports—more than all the airports combined. It is triple the capacity that the facility was designed for and it is not representative of New York. It is dirty; it is dingy; it is dark and that is not what New York is all about.”

Building begins in the fall and the new station is expected to be completed by December 2020, Cuomo said.
