Amtrak has resumed most of its service between Baltimore and Washington following a Wednesday morning water main break. However, southbound Acela Express trains will be halted until all track repairs are complete.
Regularly scheduled trains, meanwhile, may experience delays of 10 to 15 minutes for the rest of the day, Amtrak said.
The 36-inch broken pipe is expected to be replaced Thursday.
Baltimore Public Works crews have turned off the water main that had stopped most Amtrak and MARC service between the two cities. Debris including mud and trees still cover some tracks in the area.
Southwest Baltimore County, Howard County and southwest Baltimore residents are being asked to conserve water.
