WASHINGTON — Metro service on the green and yellow lines was suspended on what was already a busy traffic day due to the arrival of Pope Francis.

Green line service was suspended between U Street and Fort Totten and all yellow line service begins and ends at Mt. Vernon Square. Metro says service was restored around 11 p.m. Columbia Heights and Georgia Avenue stations were also reopened.

Service was suspended for nearly five hours.

Metro says the issue is due to a third rail power outage.

According to audio from a Metro train conductor, the outage occurred between the Columbia Heights and the Georgia Avenue stations.

D.C. firefighters evacuated the affected train, which stopped 100 feet away from the Georgia Avenue station, according to Metro Transit Police.

Metro officials say it will take some time to find the source of the outage and restore power.
