Amtrak on Monday completed a 15-month rehabilitation of one of four East River train tunnels connecting Penn Station to Queens, finishing the first phase of a post-Hurricane Sandy repair project that forced the Long Island Rail Road to cut peak-hour service by 20%. MTA Chair Janno Lieber used the milestone press conference to publicly criticize Amtrak over the disruption to commuters.
Key Takeaways
- Amtrak reopened the rebuilt Line 2 tunnel on Sunday evening after a full 15-month closure, marking the completion of the first phase of a two-phase Sandy rehabilitation project.
- MTA Chair Janno Lieber said the closure forced the LIRR to reduce peak-hour Penn Station service by 20%, resulting in significantly more crowding for riders.
- A May fire temporarily knocked out two of the three remaining tunnels, leaving the LIRR, Amtrak, and NJ Transit sharing a single tube for cross-river train movements.
- During demolition, crews removed 24,000 linear feet of running rail, 12,000 feet of third rail, 8,100 tons of ballast, and approximately 20,000 cubic yards of benchwall concrete from the century-old tunnel.
- Phase two begins later this fall with the closure of the second Sandy-damaged tunnel. The full project is expected to wrap by the end of 2027.
A Century-Old Tunnel Rebuilt From the Inside Out
The East River tunnels are among the most consequential pieces of rail infrastructure on the East Coast. Amtrak owns all four tubes, which together carry more than 450 trains per day for Amtrak, the LIRR, and NJ Transit. When Hurricane Sandy flooded two of those tunnels with corrosive saltwater in 2012, it set the clock on a structural deterioration problem that could only be fully addressed by taking each tunnel offline.
Amtrak began work on Line 2 in the summer of 2025, fully closing the tunnel to service for the first time since its original construction over a century ago. The scope of what crews found once inside reinforced why a full closure was necessary. Decades-old infrastructure had to be stripped entirely: 24,000 linear feet of running rail, 12,000 feet of third rail, 8,100 tons of ballast, and 8,000 railroad ties were removed before reconstruction could begin.
The benchwall demolition alone produced roughly 20,000 cubic yards of concrete, the equivalent of more than 650 construction dumpsters. Crews used robotic demolition machines and hydraulic rock splitters to work safely in tight spaces, uncovering blocked drainage systems, deteriorated conduits, and widespread water infiltration that had been hidden behind the original walls for decades.
The Rebuilt Tunnel Introduces Modern Safety and Drainage Systems
The reconstructed Line 2 now features a set of upgrades designed to extend the tunnel’s service life by another century. Amtrak’s project team installed modern direct-fixation track that improves both drainage and ride quality, replacing the ballasted track bed that had been in place since the tunnel’s original construction. A redesigned benchwall configuration with high and low sections improves emergency egress and maintenance access throughout the three-mile tube.
New signal, communication, and power systems run the length of the tunnel. Advanced fire and life safety systems, including expanded heat and smoke detection, improved emergency communications, and clearer evacuation paths, address vulnerabilities that were exposed during the construction period itself. A brighter lighting system gives train operators improved visibility, and a wider drainage system moves water out more efficiently than the original infrastructure ever could.
Passenger service returned to the rebuilt tunnel on Sunday evening, restoring the fourth East River tube to active rail operations for the first time since the closure began.
MTA Chair Lieber Criticizes the Project’s Impact on LIRR Riders
The milestone did not come without friction between the two agencies. MTA Chair Janno Lieber used Amtrak’s celebratory press conference at Penn Station to deliver a pointed assessment of what the closure cost LIRR riders. The LIRR is the nation’s busiest commuter railroad, and every one of its Penn Station trains depends on the East River tubes to cross the river.
Lieber stated that the project forced the LIRR to reduce its peak-hour service into Penn Station by 20%, resulting in heavier crowding for commuters who had no alternative routing. The MTA had initially pushed for a “repair in place” approach, arguing that Amtrak could perform the work during nights and weekends while maintaining daytime service. Amtrak rejected that model, countering that it would have extended the project timeline by years with, in the words of Amtrak Vice President of Infrastructure Project Delivery Warren LeBeau, “significantly more impact to riders.”
The 15-month closure also produced several acute disruptions beyond the planned service reductions. In May, a fire temporarily disabled two of the three remaining active tunnels, compressing all LIRR, Amtrak, and NJ Transit cross-river operations into a single tube. The month prior, an LIRR train struck debris inside the tunnel, triggering additional delays while workers inspected the tracks. Lieber called these incidents evidence that the project had “some bad episodes,” while acknowledging that LIRR President Rob Free’s insistence on standby work crews and weekend inspections helped limit their frequency.
Construction Lessons Set the Stage for a Shorter Phase Two
Amtrak has already begun applying lessons from the first phase to the planning for Line 1, the second Sandy-damaged tunnel scheduled for closure later this fall. Among the adjustments: crews discovered they could demolish benchwall concrete and pump replacement material from both ends of the tunnel simultaneously, rather than operating solely from the Queens side. Changes in construction sequencing are also expected to compress the overall timeline for the second phase.
LeBeau stated that the construction team’s experience with the variable conditions inside the century-old tunnel, where the density and composition of concrete changed unpredictably along the three-mile stretch, will allow more efficient planning for Line 1. Amtrak expects the second phase to wrap by the end of 2027, completing the full rehabilitation of both Sandy-damaged tubes.
Lieber signaled that the MTA would remain aggressive in holding Amtrak accountable during the second closure. He described the agency’s role as being “a millstone around their necks” to protect LIRR riders from service cancellations and shutdowns. The dynamic between the two agencies, one owning the tunnels and the other running the busiest commuter service through them, remains a defining tension in regional rail infrastructure planning.

FAQs
Why Did Amtrak Fully Close the Tunnel Instead of Repairing It During Off-Hours?
Amtrak determined that the century-old tunnel required a complete structural rebuild that could not be safely or efficiently performed during overnight and weekend windows. The national railroad argued that a “repair in place” approach, which the MTA had advocated, would have extended the project timeline by years and created more cumulative disruption to riders than a single continuous closure.
How Many Trains Use the East River Tunnels Each Day?
More than 450 trains operated by the LIRR, Amtrak, and NJ Transit travel through the four East River tunnel tubes daily. The LIRR accounts for the largest share of that volume, using the tunnels for all of its service into and out of Penn Station Manhattan.
When Does the Second Phase of the Project Begin?
Amtrak plans to close the second Sandy-damaged tunnel, Line 1, later in the fall of 2026. Before that closure begins, Amtrak will complete infrastructure hardening work on the remaining active tunnels to help maintain reliable service. The full two-phase project is expected to be finished by the end of 2027.
