MANHATTAN — A Third Avenue track fire on the L line temporarily halted service and sparked a commuter nightmare during Monday morning's rush hour, according to train announcements and commuters.

Manhattan-bound trains were terminating at Bedford Avenue as of 8:33 a.m. because of FDNY activity in the Third Avenue station, according to the MTA.
