A water main break caused train tracks near BWI Airport to become submerged Wednesday morning, shutting down Amtrak service between Baltimore and Washington for hours and causing delays along the Eastern seaboard.

The service disruption began at about 7:45 a.m. after Amtrak received a report from the Baltimore Department of Public Works about a 36-inch water main break in Halethorpe, which is near Baltimore-Washington Thurgood Marshall International Airport.
