NEW YORK - With all the recent problems affecting train service in and out of Penn Station, there's a renewed push to get a major rail project back on track.

A draft environmental impact study was released Thursday on a proposed new rail tunnel under the Hudson River.

It predicts the project would ease congestion on the current tunnel, which was badly damaged during Hurricane Sandy and is over a hundred years old.

The study details how the "Gateway Project" would affect life and traffic on Manhattan's West Side, as well as the overall benefits to the region.

“You’ll have a more reliable ride here into Penn Station. It ties in very well with the other Penn Station improvements going on. And the idea is to make sure, going forward, and for future generations, we have the capacity for the New York region to continue to grow and build the kind of economy we want our children and grandchildren to have," said John Porcari of the Gateway Development Corporation.

The existing tunnel carries more than 450 Amtrak and New Jersey Transit trains in and out of Manhattan daily.

Lawmakers from New York and New Jersey have called on Washington to help fund Gateway.

The final version of the impact study will be released by next March.
