NEC Gateway Improvements Hudson Yard Tunnel and MOE Facility

Bringing Enhanced Rail Service through Extensive Coordination

The NEC Gateway Concrete Casing Project will provide for the initial phase of expanded passenger rail access to Manhattan. The overall project scope includes additional tunnels and tracks between Penn Station and Newark. LiRo is providing construction management services for construction executed via the design-build delivery method.

About the Project

To preserve available track space for the Gateway tunnel project in Manhattan, Amtrak is planning to construct a 900 ft long concrete box in the LIRR West Side Storage Yard where the Hudson Yards development is to be built. In addition, to further create resiliency in the passenger rail system in response to disaster, and particularly flooding, new construction is designed to withstand flood levels at new standards, using criteria that would have prevented the flooding caused by Superstorm Sandy.

The project is designed to preserve an underground right-of-way for future expansion of rail service via two new tunnels under the Hudson River to Penn Station and is divided into two phases. Construction of the concrete casing tunnels will consist of an open cut excavation going 10 to 20 ft into bed rock with secant piling as the support of excavation.

As part of the project, a portion of the LIRR Maintenance of Equipment (MoE) facility will be demolished and rebuilt. In addition to the partial demolition of the facility, six service tracks that lead to the facility and parts of two yard tracks will be salvaged and reinstalled. A number of utilities will be impacted due to construction, with many being removed, relocated, restored, and/or replaced.

Project Challenges & Solutions

Extensive operations coordination will be required with Long Island Rail Road, Related Development, and Amtrak during the relocation of the maintenance facility and the construction of the Amtrak tunnel structure. LiRo will ensure that train operations are only impacted as per the planned track outages and scheduled train interruptions for the project.
