A disabled Metro train trapped passengers underground for more than an hour Thursday afternoon, Metro and passengers said.
Metro said a Blue Line train had a mechanical issue near the Rosslyn station.
Two riders said passengers were trapped for 1 hour and 15 minutes. Crews led between 100 and 200 passengers through two lined-up trains, and riders were able to step onto the Rosslyn station platform.
Blue Line trains single-tracked between the Foggy Bottom and Arlington Cemetery stations. The disabled train had been cleared from the tracks about 4 p.m.
Metro riders should expect residual delays on the Yellow and Blue lines.
No injuries or medical issues were reported.
