This work will involve demolishing the existing tunnel systems down to the concrete liner, followed by reconstructing and modernizing all tunnel systems, which include:
- Spot repair and patching of the concrete tunnel liner
- Reconstruction of the bench walls in a modern high-low configuration
- Conversion from ballasted track to a modern direct fixation track system with integrated drainage
- Installation of new, state-of-the-art fire and smoke detection systems
- Replacement and modernization of signal, traction power, standpipe and drainage systems
During the work, which is expected to last approximately three years, Amtrak plans to maintain the vast majority of service, with slight schedule changes for
Northeast Regional and
Acela trains, as well as modifications to some Long Distance and State Supported services. The project will also not result in a major disruption to LIRR or NJ TRANSIT service. Amtrak and the railroad partners are coordinating closely to mitigate service impacts and will provide detailed service information via numerous channels in the coming months.
Preparatory work is already underway in Sunnyside Yard, with major construction expected to begin in late 2024 and continue through 2027.
