In the early 1990s, Senator Daniel Patrick Moynihan proposed turning part of Manhattan's James A. Farley Post Office—a McKim, Mead & White building just west of Madison Square Garden—into a new Pennsylvania Station, partially making up for the destruction of the same firm’s landmark station in 1963.

More than 20 years later, part of the plan is moving forward. Governor Andrew Cuomo announced in August that construction is finally underway on the new $1.6 billion Moynihan Train Hall, a 255,000-square-foot concourse topped by nearly an acre of glass.
