Beginning October 2026, there will be some disruptions to the Virginia to Washington rail service as Amtrak begins to repair and modernize some services within the First Street Tunnel located at Washington Union Station. The disruptions will take nine days. During that time, rail services will be replaced with infrastructure that is safer and more efficient and will modernize the A-Interlocking system. While these improvements are made, there will be detours and some cancellations. Replacement bus service will be utilized while the work is performed. Parking at stations will remain available.

Thousands of rail passengers travelling between Washington, D.C., and Virginia will need to prepare for temporary travel changes in October 2026 as Amtrak begins a major infrastructure renewal project inside the First Street Tunnel near Washington Union Station. The nine-day construction shutdown will affect Amtrak and Virginia Railway Express (VRE) services by closing the A-Interlocking junction, leading to revised train schedules, replacement bus services and temporary route adjustments. The project will replace ageing rail equipment, remove operational restrictions and strengthen one of the busiest passenger rail connections in the United States.

Critical Washington rail junction to close for nine-day reconstruction

The temporary closure is scheduled to begin after the last services operate on Friday, October 16, 2026, with normal train operations expected to return on Monday, October 26, 2026. During this period, the A-Interlocking system will be unavailable while construction crews carry out a complete renewal of the railway infrastructure.

The A-Interlocking junction plays a central role in managing train movements between Washington Union Station and Virginia. The area has experienced increasing operational challenges as older components approach the end of their service lifespan.

Existing switches and track connections have forced trains to operate under a 10 mph speed restriction through the junction. The upgrade programme is designed to remove these limitations and create a smoother, faster and more reliable rail connection.

Due to the location of the work inside the narrow First Street Tunnel, engineers cannot safely complete the reconstruction while trains continue passing through the area. A full shutdown will provide uninterrupted access for teams to replace essential railway components.

Extensive track renewal work planned inside First Street Tunnel

The construction project will involve a wide range of engineering improvements aimed at upgrading the tunnel’s railway systems.

Crews will replace outdated switches and crossovers with advanced equipment designed to improve train movements and reduce delays. Modern electric switch technology will be installed, while sections of the track base will be rebuilt to improve long-term stability.

The project will also replace two double-slip switches and a diamond rail crossing, both of which are important components of the junction. Additional work will include renewing ballast beneath the tracks and improving drainage systems inside the tunnel.

The shutdown window has been carefully planned to allow continuous construction activity. Preparatory work, including the assembly and testing of replacement track components, will take place before the closure begins.

This approach is expected to help construction teams complete the work within the scheduled nine-day period and minimise the impact on passengers.

Amtrak passengers face temporary route changes south of Washington

The biggest service impacts will be felt by passengers travelling south of Washington, D.C., as several Amtrak routes will require temporary operating changes.

Northeast Regional services between Washington, New York and Boston will continue operating. However, routes connecting the capital with Virginia and southern destinations will run under modified arrangements.

Amtrak Virginia will maintain limited train services during the disruption. A round trip between Norfolk and Alexandria will continue, along with another service linking Roanoke and Alexandria.

To help passengers continue their journeys, replacement buses will operate between Alexandria and Washington Union Station. The buses will be coordinated with train schedules to support transfers.

Additional express bus services will connect Washington with destinations throughout Virginia, including Richmond, Charlottesville, Roanoke, Lynchburg, Norfolk, Newport News, Williamsburg and Virginia Beach.

Travellers using affected routes will need to consider longer journey times because of the temporary transfer arrangements.

Major long-distance Amtrak services receive temporary adjustments

The infrastructure closure will also affect several long-distance Amtrak routes operating through the Washington area.

The Carolinian service will continue between New York and Washington, while the southern section between Alexandria and Charlotte will operate separately. Passengers travelling through the closed area will transfer between Washington and Alexandria using alternative transport.

The Cardinal route will temporarily operate only between Chicago and Indianapolis.

The Floridian service will be split into two separate operations, with one section running between Chicago and Pittsburgh and another between Jacksonville and Miami.

The Silver Meteor will operate separately between New York and Washington and between Jacksonville and Miami. Palmetto trains will operate only between New York and Washington, while Crescent services will continue between New York-Washington and Atlanta-New Orleans.

These temporary arrangements will allow essential rail connections to continue while major construction work takes place.

VRE prepares alternative travel options during shutdown

Virginia Railway Express will also adjust its commuter operations during the closure of the A-Interlocking system.

The commuter rail network will continue serving most stations but will temporarily suspend direct rail access into Washington Union Station. Passengers travelling from Virginia towards Washington will need to use alternative connections.

Alexandria will serve as an important interchange point during the disruption. Passengers can continue their journey into Washington using the nearby King Street-Old Town Metro station, which provides access through the city’s rapid transit network.

The final VRE timetable for the October construction period will be released after operational planning is completed.

Modernised rail infrastructure expected to improve future travel

The First Street Tunnel upgrade represents a major investment in improving passenger rail reliability around Washington Union Station.

Once completed, the renewed A-Interlocking system will help reduce delays, improve train movements and provide stronger infrastructure for future passenger demand.

Rail operators are preparing passenger assistance measures, alternative travel arrangements and updated information to help travellers manage the temporary disruption.

While there will be temporary problems with the October shutdown, the benefits associated with the completion of the project should include a safer, speedier, and more reliable connection for rail service between Washington, D.C. and Virginia.
