The Shadow
WASHINGTON, Va. (VR) — Amtrak today announced, “Pause for Progress,” a critical infrastructure upgrade scheduled to take place this fall in the First Street Tunnel just south of Washington Union Station.
For a nine-day period, from October 16–26, 2026, Amtrak will implement a temporary service outage at “A-Interlocking” to replace aging track components and improve reliability along the Northeast Corridor and into the Southeast. The outage will begin after the close of service Friday, Oct. 16, and conclude before service resumes Monday morning, Oct. 26.
A-Interlocking is a critical track and control point within the First Street Tunnel, responsible for routing all Amtrak and Virginia Railway Express (VRE) train movements between Washington Union Station and Virginia. The existing switches and crossovers are beyond their service life, requiring a 10-mph speed restriction that impacts operations. “Pause for Progress” is designed to address those limitations and help prevent larger, unplanned service disruptions.
A short-term, coordinated outage is more efficient due to the confined tunnel environment and limited access, making phased construction impractical. Customers traveling to or from Washington, D.C. from the south should expect significant service reductions and train cancellations.
