 Parts of New London, Hartford, New Haven, Litchfield, and Fairfield counties, from Greenwich to Danbury and Bridgeport, were affected, although most of the state had power all evening, aside from a few momentary interruptions that caused computers to reboot.Metro-North trains stopped and remained on the tracks for hours, until they could be towed to the nearest station.Generally, most of the state east of Interstate 91, and some places west of I-91, had power during the duration of the blackout, with some of New Haven's eastern suburbs being seen as the easternmost extreme of the effects of the blackout.
