Hudson River Railway

  $8 million study concerning 8 km rail tunnel from Secaucus NJ on the west bank, under the Hudson River to Penn and Grand Central stations in Manhattan to complement East Side Access project for Long Island Railroad. Final plan to be selected by 2001. June 1999.   $2 billion funding approved by the Senate for proposed fourth rail line under the Hudson River as part of a $7 billion rail programme for Amtrak to upgrade high-speed rail corridors throughout the US. Three proposed options. Option G takes the new tunnel to New York's Penn station, and Grand Central for a cost of $4-$5 billion. Option P ends at Penn station and would cost $3 billion. Option S would take the tunnel to Penn station, and then to the Sunnyside rail yard in Queens for $4-$5 billion. Neither option P or S gets to the East side so that option G is considered the most attractive. 47/01.   The New Jersey Transit approved to undertake a $4.9 million environmental impact study for two one-way tunnels under the Hudson river. The new tunnel would link the Northeast Corridor line with Pennsylvania station in Manhattan, placing the parallel tunnels somewhere in the northern Hoboken-southern Weehawken area on the Hudson's west bank and midtown Manhattan to the east. The project is being undertaken in conjunction with the Port Authority of New York and New Jersey and the Metropolitan Transportation Authority (MTA) which operates New York City's commuter trains and stations. The new tunnel would cost $5 billion.Visit www.njtransit.com and www.accesstotheregionscore.com 42/02.  The New Jersey Transit board awarded a $4.9 million contract to Parsons Brinckerhoff and Systra Consulting to begin environmental impact studies of a proposed new rail tunnel between New Jersey and Manhattan. The two firms plan to finish the study by 2005. The next step would be to secure $16 million in federal funding for engineering studies. The plan for the tunnel includes two one-way tubes under the Hudson River between the Hoboken-Weehawken border and the Chelsea section of Manhattan. The entire tunnel project is estimated to cost up to $5 billion, most of which would come from federal sources. The tunnel would likely take more than 10 years to complete. Visit www.njtransit.com, www.pbworld.com and www.systraconsulting.com 27/03.Congress will grant $5 million in federal funds to begin the studies for developing a new rail tunnel between New York and New Jersey. The funds will be included in the 2004 transportation appropriations bill. The project could cost as much as $5 billion. The $5 million initial appropriation will be used to produce a draft environmental impact statement, one of the first steps necessary to prepare for construction. New Jersey Transit and the Port Authority of New York and New Jersey will coordinate the study.
