Metro fully restored service about 11 p.m. after a northbound train got stuck due to a power loss on the Green and Yellow lines Tuesday evening.
Firefighters helped escort 500-600 passengers out of a Metro tunnel between the Columbia Heights and Georgia Ave-Petworth stations Northwest D.C.
Service was suspended between the U Street and Fort Totten stations for hours because of the power loss.
The service disruption came on the eve of Pope Francis' historic Mass near Fort Totten.
No one was injured, according to Metro.
One passenger described the events to News4's Darcy Spencer, saying the lights on the train flickered and then slowly came to a stop. They were stuck for more than an hour, Takiyah Johnson said.
To evacuate, she had to walk through the tunnel, aided by emergency lighting and firefighters, Johnson said.
Metro advised commuters to take buses or the Red Line if possible. People leaving the Washington Nationals game and headed to stations between Fort Totten and Greenbelt were told to transfer to the Red Line at Gallery Place and back to the Green Line at Fort Totten.

Trains on the Blue, Orange and Silver lines are also delayed, after a transformer fire Monday near the Stadium-Armory station.
Residents were advised to take Metro rather than drive during Pope Francis' visit to Washington Tuesday through Thursday, and use the Fort Totten station to get to the Basilica of the National Shrine of the Immaculate Conception on Wednesday.
