A power outage at 81st Street snarled several subway lines for more than two hours Friday.
Four trains were stuck on the tracks when power went out around 9 a.m. Friday, and were diverted to Columbus Circle.
Until about 11:30 a.m., there were no A or D trains between Columbus Circle and 125th Street, no B trains between Brighton Beach and 145th Street and no C trains between Euclid Avenue and 168th Street.
E trains were running on the F line to Second Avenue, and there were no M trains between Forest Hills-71st Avenue and Essex Street.
