Manhole fires in Brooklyn yesterday caused disruptions on five subway lines Sunday evening and cut power to up to 1,500 residents in Boerum Hill. “Around 5:45 p.m., a manhole fire at Dean and Smith streets disabled power to signals on F and G lines, while nearby, at Bergen Street and Fourth Avenue, problems on the power lines cut electricity to signals on the Nos. 2, 3, and 4 lines. Subway service was shut down along section of the lines, mostly between Brooklyn and Manhattan, for more than an hour.” No word on whether all power has been restored.–amNY
