Passenger rail modernization on the Northeast Corridor
On the rolling stock side, high-speed, American-built NextGen Acela trains are now in service, as reported by Railway Supply. New Airo trainsets are arriving in 2026.
On the infrastructure front, construction is making serious progress across several projects. That list includes the William H. Gray 30th Street Station Redevelopment (Philadelphia), Portal North Bridge (New Jersey) via the NJ TRANSIT Portal North Bridge page, the East River Tunnel Rehabilitation Project (New York City), and the Connecticut River Bridge (Connecticut), along with additional work.
