Amtrak plans to suspend most passenger rail service between Virginia and Washington, D.C., for 11 days in mid‑October to complete critical track work at the A‑Interlocking control point inside the First Street Tunnel, the company announced.
What the shutdown means for travelers
The work will begin on Oct. 16 and continue through Oct. 26. During that period, Amtrak said trains that normally travel between Virginia and Union Station will effectively end at Alexandria, with only a limited number of trains continuing north into the District. Most passenger movements to and from Richmond, Charlottesville, Lynchburg and the Hampton Roads region will be handled by express buses.
- Service reductions: Significant cancellations and route changes are expected for passengers traveling to or from Washington, D.C., from the south.
- Terminations at Alexandria: Trains through Virginia will generally terminate at Alexandria instead of Union Station.
- Bus replacements: Express buses will cover the majority of trips that normally run through the First Street Tunnel.
Amtrak described the A‑Interlocking switches and crossovers as being "beyond their service life," a condition that has required the railroad to operate under a 10 mph speed restriction in the area — a constraint that has pressured schedules and reliability.
"Customers traveling to or from Washington, D.C. from the south should expect significant service reductions and train cancellations,"
The agency said the planned work — part of an initiative Amtrak calls "Pause for Progress" — will replace outdated switches, install modern electric switch systems and repair and strengthen the tunnel's foundation. The upgrades are intended to improve safety and reliability, reduce delays and support future demand on the corridor that serves both Amtrak and Virginia Railway Express (VRE).
Responses from regional rail partners
Representatives from Virginia Railway Express and the Virginia Passenger Rail Authority acknowledged the disruption while emphasizing the project's long‑term benefits for the region's rail network.
"VRE supports Amtrak's work to upgrade A‑Interlocking in the First Street Tunnel, and we applaud investments that keep our rail corridor in a state of good repair,"
VRE CEO Katie Choe added that while some riders will need to change their plans during the week of Oct. 19–23, the upgrades are expected to allow more reliable service and improve the passenger experience at Union Station.
Operational context and immediate impacts
The A‑Interlocking is the routing point that allows trains from Virginia to access Union Station and the broader Northeast Corridor network. Amtrak noted that once trains are north of Washington, normal operation resumes on the Washington–New York–Boston segment. However, for the 11‑day work window the southern approach to the District will have significantly curtailed rail access.
| Date range | Planned impact |
|---|---|
| Oct. 16–26 | Major suspension of service between Virginia and Washington; most trains to terminate at Alexandria; express buses substitute for many routes |
Amtrak said the project will replace aging track components and modernize switch operation with electric systems, which are expected to reduce future maintenance needs and delays caused by the current temporary 10 mph restriction.
What travelers should do
Amtrak and regional partners have urged passengers to check schedules and plan for alternate travel during the work period. Riders who normally travel to Union Station from Virginia should expect to either disembark in Alexandria and arrange onward transport or use the express bus services provided for affected routes.
Passengers with existing reservations should monitor Amtrak and VRE communications for detailed routing and replacement bus information. Once north of Washington, Amtrak trains will continue to operate normally on the rest of the Northeast Corridor.
The mid‑October project underscores the challenges of maintaining an aging rail infrastructure that serves a growing and heavily used passenger network into the District. While the short‑term disruption will be significant for many commuters and travelers, authorities say the upgrades are necessary to improve safety and reliability for years to come.
