U.S. Transportation Secretary Elaine Chao told a House subcommittee Thursday that federal officials are working with Amtrak on a plan to accelerate the work now on the 110-year-old tunnel.
The new tunnel, proposed nine years ago as part of the larger Gateway project to transform rail capacity in the New York region, is mired in a funding dispute between the federal government and New York and New Jersey and currently is ineligible for federal grants.
Amtrak already shuts down one of the existing tunnel's two tubes during overnight and weekend hours to repair damage accelerated by flooding from 2012's Superstorm Sandy. The Gateway plan called for shutting down the tunnel for a complete overhaul once a new tunnel is built, but Chao said Thursday that beginning the repair work now “is the right move.” She noted that building a new tunnel would take seven to 10 years and cost an estimated $11 billion, under the most favorable conditions.
The new plan calls for more extensive repairs that will require further service disruptions, said Stephen Gardner, Amtrak's senior executive vice president and chief operating and commercial officer.
The most disruptive repairs could “require a complete outage at some point," he added.
The problems — including water leaking in, crumbling walls, an outdated track bed and overhead wire issues — are so extensive that they won't all be repaired, even under the new plan, Gardner conceded.
Gardner also cast doubt on the idea that 12,000-volt electrical cables currently encased in concrete damaged by Sandy can be installed on racks on the tunnel walls. New York Gov. Andrew Cuomo opted for that approach to avoid a lengthy planned shutdown last year of New York City's L subway line connecting Brooklyn and Manhattan. The idea has gained traction for the Amtrak tunnel in recent months, and Chao referred to it Thursday.
“This is not the same situation as the Canarsie tube, which is low voltage, 600 DC volts," Gardner said. "People get confused about applying a method to a completely different technological solution. With 12,000 volts, it explodes, it arcs. You have to protect it in a fireproof, very robust encasement of some sort."
More than 400 trains carrying more than 200,000 people use the tunnel daily, and the impact of equipment or infrastructure failures there can spread quickly up and down the corridor between Boston and Washington, D.C., which handles more than 2,000 trains daily operated by Amtrak and several commuter railroads.
Repairs will be paid for with profits from Amtrak's Northeast Corridor service, by far its most profitable line. The money is available because legislation pushed in 2015 by U.S. Sen. Chuck Schumer, a New York Democrat, relieved Amtrak from being forced to use that money to subsidize its other, money-losing lines in the rest of the country.
“Amtrak had no choice but to go forward with this second-best solution because of the (Trump) administration’s intransigence at refusing to move forward on the Gateway project," Schumer said in reaction to Chao's announcement. "Fortunately, we were able to change the law so that Amtrak can use profits on the Northeast Corridor for capital construction like this. But we still must move forward on the Gateway project.”
