PATH trains are resuming around-the-clock service on some lines for the first time since Superstorm Sandy.

Port Authority officials say starting today trains will run 24-hours, 7 days a week, from Newark to 33rd Street, via Hoboken.

PATH trains will still run from 5 a.m. to 10 p.m. during the week on the Hoboken to 33rd Street, Journal Square to 33rd Street and Newark to World Trade Center lines.

Officials say it could be late February before they receive a shipment of replacement parts necessary to restoring service on the line between Hoboken and the World Trade Center.

Salt water flooded the Hoboken tunnels during Sandy, shorting out electrical system and corroding equipment. Officials say many of the parts were decades old and replacements are coming from a third-party manufacturer.
