Amtrak plans extensive D.C. service suspension for critical tunnel upgrades

Passengers traveling by Amtrak through Washington, D.C., this October should prepare for significant disruptions. The rail service announced Monday that it will close the First Street Tunnel, just south of Union Station, for nine days starting Oct. 16 and ending Oct. 26, to perform what it described in a news release as a "critical infrastructure upgrade."

According to Amtrak, the work involves replacing aging track components — including switches and crossovers that are "beyond their service life" — to improve reliability along the Northeast Corridor and into the Southeast. The company explained that the existing infrastructure requires a 10-mph speed restriction that currently affects operations. The project, Amtrak said, is designed to address these limitations and prevent larger, unplanned service disruptions in the future.

The outage will begin after the close of service on Oct. 16 and conclude by the time service resumes on Oct. 26. During that period, travelers should expect significant service reductions and train cancellations, particularly for trips between the District and points south. WJLA reported that the pause would mostly affect passengers coming to D.C. from the South and those heading south from the District.

In addition to replacing the switches and crossovers, workers will rehabilitate the tunnel track base, according to WTOP. To ease the disruption, Amtrak plans to supplement the loss of train service with buses. The company also said it will support customers with rebooking options and "alternative travel solutions," though specific details on the substitute routes were not disclosed.

The announcement comes as the rail service continues to focus on maintaining the aging infrastructure of the Northeast Corridor, one of the busiest rail lines in the country. The closure is set to allow crews to perform the necessary upgrades without disrupting larger, unplanned outages down the line.
