Amtrak will shut a key section of track south of Washington Union Station for nine days this October. Service stops after the last train on Friday, October 16, 2026, and resumes Monday morning, October 26. Amtrak announced the work on August 24, 2026.
The work targets A-Interlocking, a junction inside the First Street Tunnel just south of Union Station. Amtrak is calling the project Pause for Progress.
Trains north of Washington are not affected. Northeast Regional service between Washington, New York and Boston runs on its normal schedule.
Which trains change
Almost everything running south of Washington is cut back or replaced during the outage.
Northeast Regional service south of Washington drops to two Amtrak Virginia round trips to Alexandria, with bus bridges and express buses filling the rest. The Carolinian runs New York to Washington by train, buses passengers from Washington to Alexandria, then resumes rail service to Charlotte.
Long-distance routes lose their middle sections. The Cardinal runs only between Chicago and Indianapolis. The Floridian operates Chicago to Pittsburgh and Jacksonville to Miami, with nothing in between.
The Silver Meteor runs New York to Washington and Jacksonville to Miami. The Palmetto ends at Washington. The Crescent runs New York to Washington and Atlanta to New Orleans.
If your trip crosses Washington on any of those routes between October 16 and October 26, it will not run end to end.
What to do about it
Check your reservation now rather than in October. Amtrak is contacting booked passengers, but notifications for long-distance routes often arrive close to the date.
If you are booked through Washington on an affected route, you have three realistic options. Move the trip outside the window. Accept the bus bridge, which adds time and a transfer. Or rebook onto a different mode for that segment.
The bus bridges are the part people underestimate. A rail-to-bus transfer at Alexandria with luggage is not the same trip you booked, and connection times are tight.
Amtrak refund rules depend on fare type, but a cancellation caused by the carrier generally entitles you to a full refund rather than a voucher. Ask for the refund explicitly if that is what you want.
Why Amtrak is doing it now
Concentrated outages have become the standard approach for this kind of work. Doing it across nine consecutive days is faster and cheaper than nights and weekends spread over months, and it gets crews continuous access to the interlocking.
October also sits between the summer peak and Thanksgiving, which is the lowest-demand stretch on the corridor.
The tunnel work matters beyond this outage. First Street Tunnel is a chokepoint for every train entering Washington from the south, and its condition sets the ceiling on how much service can run through the station.
For readers weighing rail against flying on the corridor, our review of the NextGen Acela covers what the newer trains changed on the northern half of the route, which is the half still running normally in October.
One more thing worth knowing if you hold Amtrak Guest Rewards points. Award tickets follow the same cancellation rules as cash tickets on a carrier-caused disruption, so points come back to your account rather than converting to a voucher. Confirm the points have actually returned before rebooking, because the credit is not always immediate.
Sleeper passengers on the long-distance routes have the most to lose here. A roomette on the Crescent or Silver Meteor is expensive, sells out, and does not rebook easily into a shortened window. If you are holding one of those, deal with it in September.
Book around the window if you can. If you cannot, build in the extra hours now.
