Amtrak to shut the door on Washington's southern approach for nine days

Amtrak will suspend rail service between Washington Union Station and Virginia for nine days in October, closing the junction that routes every train heading south out of the capital so crews can replace switches that currently force trains to crawl through at 10 mph.

The outage, which Amtrak is calling "Pause for Progress", begins after the last train on Friday 16 October and runs until service resumes on the morning of Monday 26 October. The target is A-Interlocking, the track and control point inside the First Street Tunnel just south of Union Station that handles all Amtrak and Virginia Railway Express movements between the District and Virginia. Its switches and crossovers are past their service life. Crews will replace them, rebuild the tunnel track base and install modern electric switch systems.

Amtrak said a single concentrated closure is more efficient than phased work because the tunnel is cramped and hard to access, and that the project is intended to head off larger, unplanned failures later.

The impact is concentrated south of the capital. Northeast Regional service between Washington, New York and Boston will run normally. Amtrak Virginia will be cut to one daily round trip between Norfolk and Alexandria and one between Roanoke and Alexandria, with the Virginia Passenger Rail Authority running three round-trip buses to bridge the final leg to Union Station. The Carolinian will run as a train from New York to Washington, a bus to Alexandria and a train again to Charlotte. Express buses will link Washington with Roanoke, Lynchburg, Charlottesville, Virginia Beach, Norfolk, Newport News and Williamsburg. VRE will operate a modified schedule serving every station except Union Station.

The closure lands on top of Long Bridge construction, running until December 2030, which has already trimmed morning trains between Richmond and Washington.

For a railroad that has spent August announcing nearly $3bn in federal grants for new trains, the October pause is a reminder that the Northeast Corridor's oldest bottlenecks still get fixed one tunnel at a time.
