SUPERTUNNEL

Supertrains need their supertunnels. And it's about time one was built.

Oct. 15 (Bloomberg) -- New Jersey's state transit agency moved a step closer today to building a new $7.6 billion train tunnel under the Hudson River to speed rail travel to and from Manhattan and improve the rides of thousands of daily commuters.

Construction is scheduled to be completed by 2017. The new passageway, consisting of two side-by-side single-track tunnels, would bring trains into an expanded Pennsylvania Station under 34th Street in Manhattan.

The two current single-track tunnels that carry Amtrak and New Jersey Transit trains between Manhattan and New Jersey were completed in 1909, and there is no room for more traffic during peak hours.
