The New York area seems to have suffered the worst damage.\r\nNorfolk Southern is advising customers to continue to expect delays in freight, while CSX implemented an embargo on traffic originating on other railways and travelling to an area stretching from Boston to Philadelphia. The railway says the embargo is necessary to avoid congestion on the network and support a fluid recovery when the storm passes. CSX train operations remain suspended on its network from Richmond, Virginia, north to Albany.\r\nSome passenger services have either been partially restored or are scheduled to be restored later this afternoon. Massachusetts Bay Transportation Authority commuter rail, Red, Blue and Orange metro lines and Mattapan Hi-Speed Line had all resumed service, but the Green Line's D-Branch sustained wire and pole damage requiring a bus replace service. Maryland Transit Administration started to operate limited service from noon today. Washington Metropolitan Area Transit Authority will restore metro services this afternoon on modified schedules and expects to resume normal service levels tomorrow morning.\r\nMeanwhile, all train services remain suspended on NJ Transit, Southeastern Pennsylvania Transportation Authority (Septa), New York Metropolitan Transportation Authority's (MTA) commuter and subway lines and Amtrak's Northeast Corridor.\r\nNew York's rail network seems to have taken a particularly brutal hit with MTA chairman Mr Joseph Lhota saying that the system "has never faced a disaster as devastating as what we experienced last night.\r\n"As of last night, seven subway tunnels under the East River flooded," Lhota continued. "Metro-North Railroad lost power from 59th Street to Croton-Harmon on the Hudson Line and to New Haven on the New Haven Line. The Long Island Rail Road evacuated its West Side Yards and suffered flooding in one East River tunnel.\r\n"We are assessing the extent of the damage and beginning the process of recovery. In 108 years, our employees have never faced a challenge like the one that confronts us now. All of us at the MTA are committed to restoring the system as quickly as we can to help bring New York back to normal."
