Red Line trains single-tracked after a train struck a power line Wednesday morning.
The train was traveling from Grosvenor to Medical Center when it struck a low-hanging Pepco wire just before 11:30 a.m., Metro officials said.
The wire was knocked down by a Public Works employee who hit a pole with a lawn mower.
Trains single-tracked between Grosvenor and Medical Center for a couple of hours.
The train did not sustain any damage.
Pepco said about 2,000 customers in the area are without power. Permanent repairs will be made after rush hour.
