Amtrak Begins B&P Tunnel Replacement Work

Amtrak is ready to begin early construction activities as part of the B&P Tunnel Replacement Program. The first project is set to kick off March 10 in the Halethorpe and West Baltimore areas. The work includes replacing aging wooden ties with new concrete ties, installing new rail, and completing track drainage improvements.

The project is funded by a grant from the FY 2019 Federal-State Partnership for the State of Good Repair Program. The upgrades will enable high‐speed operations on all four tracks along this track segment.

“The collaboration between the state of Maryland, Amtrak, our federal partners and Baltimore is making the long-awaited replacement of the B&P Tunnel a reality,” said Maryland Transportation Secretary Paul J. Wiedefeld. “This initial work by Amtrak is laying the foundation for the new Frederick Douglass Tunnel, and will help us improve mobility, access and service for riders throughout the region.”

The overnight work associated with track and tie replacement will take place on Track A from Winans to Bridge interlockings and is not expected to impact rail service. Bridge interlocking is located north of West Baltimore Station and Winans interlocking is at the south end of Halethorpe Station. The first phase of the project is targeted for completion early this summer, with additional project work related to the replacement of an existing turnout in Winans with a new high-speed turnout in a future phase.

At nearly 150 years old, the B&P Tunnel is Amtrak’s oldest tunnel on the Northeast Corridor and a single point of failure for both MARC and Amtrak trains. The 1.4-mile tunnel, connecting Baltimore to Washington, D.C., suffers from a variety of age-related issues such as excessive water infiltration, a deteriorating structure, and delays that impact more than 10% of weekday trains.

The $6 billion program will eventually be advanced by Amtrak and its partners by utilizing federal funding provided by the IIJA. The program is comprised of several investment projects to construct new bridges, rail systems and track, an ADA-accessible West Baltimore MARC station, and the new Frederick Douglass Tunnel, which will include two new high-capacity tubes for electrified passenger trains.
