An expansion of the passenger facilities at New York's crowded Penn Station into the General Post Office across Eighth Avenue has been put on an accelerated basis and could open by 2020, according to plans announced on September 27 by New York Gov. Andrew Cuomo.  In an addition to the project, originally proposed by the late Sen. Patrick Moynihan (D-NY), Long Island Rail Road passengers will also be included in the Post Office addition; previously, only Amtrak was slated to occupy the space.  NJ Transit riders will not be part of the project, but moving some Amtrak and LIRR riders to the new space should help reduce congestion in the current Penn Station concourses. (Since a number of the platforms used by NJT do not extend far enough west, building access to them from the Post Office area might be impractical anyway.) Although Gov. Cuomo made the announcement, apparently New York State may not have to contribute much funding to the project. Developers Related Companies and Vornado will pay $600 million for the develpment rights, which will include retail space; $425 million will come from the LIRR, the Port Authority, and Federal sources; and, although New York State will contribute $570 million, most of that is expected to come from sale of the air rights over the space.  The plan includes a large skylight over the expansive passenger concourse; contractors will be the giant Skanska AB.  The story was reported here by Charles V.
