Metro-North to Resume Full Service on Monday The Metro-North Railroad is expected to return its New Haven line to full service by Monday, transit officials said, nearly two weeks after a power loss in Mount Vernon, N.Y., upended commutes for tens of thousands of travelers across the Northeast. Consolidated Edison, which operated the feeder cable whose failure on Sept. 25 prompted the disruption, said on Friday that it had connected and energized a separate, 138,000-volt feeder to the rail line, clearing the way for service to return. The Metropolitan Transportation Authority said it would conduct tests on the line over the weekend, but barring any setbacks, the railroad is expected to resume normal operations in time for the Monday morning rush. Since last week, the authority has relied in part on a makeshift network of diesel trains and buses to provide limited service on the line, which is Metro-North's busiest. The feeder cable that will power the rail was taken offline deliberately last month as part of equipment upgrades for Metro-North, and was originally not scheduled to be available until mid-October. In recent days, though, the utility said it hoped to restore the feeder by Monday. According to a preliminary review by Con Edison, the failure of the second feeder last week was most likely related to the utility's work disconnecting the first. Lawmakers have called for state and federal investigations into the case, and any findings could be of significant financial consequence to both the utility and the transportation authority. On Tuesday, the authority's board approved a plan to offer credits to New Haven line riders with weekly or monthly tickets. At least one board member has suggested that Con Ed should reimburse the authority for lost revenue if the utility is found liable.
