Reston-area commuters who ride Virginia Railway Express (VRE) into Washington will lose direct D.C. service for nine days in October while Amtrak replaces worn-out track equipment in a tunnel south of Union Station.

The shutdown, which Amtrak calls "Pause for Progress," begins after the close of service Friday, Oct. 16, and ends before trains resume Monday morning, Oct. 26. Reston has no Amtrak station, but the outage will ripple through the VRE Manassas Line and Metrorail connections that area commuters use to reach the District.

"Every train that comes through D.C. that's traveling south goes through A-Interlocking," Greg Michalski, Amtrak's deputy chief of production construction, told Railway Supply.

The A-Interlocking is a set of switches and crossovers inside the First Street Tunnel. Amtrak said the components are "beyond their service life" and currently force a 10-mph speed restriction, the Virginia Mercury reported. Crews plan to work around the clock for all nine days, replacing the switches, installing modern electric equipment, renewing the ballast beneath the tracks and fixing drainage problems.

What changes for riders

During the outage, Virginia-bound Amtrak trains will end at Alexandria. Amtrak Virginia will keep one daily round trip between Norfolk and Alexandria and one between Roanoke and Alexandria. Three round-trip bus shuttles will connect Alexandria with Union Station, timed to meet trains.

Express buses will also link D.C. directly with Richmond, Charlottesville, Lynchburg, Roanoke, Norfolk, Newport News, Williamsburg and Virginia Beach, according to Amtrak's announcement. Northeast Corridor trains between Washington, New York and Boston will run normally.

VRE and Metro options

VRE trains on the Manassas and Fredericksburg lines will not continue into D.C. during the outage. Inbound trains will instead terminate at Alexandria and Crystal City, according to Railway Supply. Riders with valid VRE tickets or passes can transfer to Metrorail at King St-Old Town or Crystal City at no extra fare.

VRE is still finalizing its modified schedule for the outage period.

Amtrak's Alexandria station is about 0.2 miles from the King St-Old Town Metro stop, where Yellow and Blue Line trains run every eight to 15 minutes. Amtrak estimates the Metro ride to downtown Washington takes about 20 minutes.

VRE CEO Katie Choe said some passengers will need to adjust plans during the week of Oct. 19–23 but called the upgrades necessary for long-term reliability.

Why it matters

Riders will need alternatives. Virginia Passenger Rail Authority (VPRA) Chief Operating Officer Mike McLaughlin said just over 40% of Amtrak Virginia passengers connect to the Northeast Corridor through the A-Interlocking route. VPRA said it has coordinated with Amtrak, CSX, Norfolk Southern, VRE and the North Carolina Department of Transportation to minimize the impact.

VPRA Executive Director DJ Stadtler acknowledged the disruption but said the agency is working to keep riders moving. Regional transit authorities are also warning drivers to expect heavier traffic on I-395, I-95 and the George Washington Memorial Parkway as commuters shift to cars and rideshares.

Amtrak said the finished work will reduce delays, improve safety and help meet future demand. Updated schedules will be posted at amtrak.com and vre.org as the Oct. 16 shutdown approaches.
