There was no M train service between Delancey Street-Essex Street and Forest Hills-71st Avenue, but by 3 p.m. it had been restored with delays, according to the agency. The service disruption appeared to be the result of a Con Edison power outage, which caused a signal failure in Queens at about 2 p.m., according to the MTA. A Con Edison spokesman said a voltage dip affected the signals, but did not affect area homes or businesses. A crew was heading to Queens to address the problem, he said. Disrupted lines included the F — which had trains holding in stations from 21st Street-Queensbridge to Jamaica-179th Street in both directions — northbound trains running on the G line, E trains stopping along the C line, and R trains stoping along the Q line. By 3 p.m., service had resumed on the E, F, M and R lines with delays in both directions on each, according to the MTA.
