At about 10:50 a.m., MCFRS responded to reports of smoke in the inbound tunnel, north of the Medical Center station near the Pooks Hill Road portal. The smoke reportedly is a result of an arcing insulator, “an insulator along the third rail that may be giving off sparks or smoke,” according to Metro.
There were no reported injuries and MCFRS units began clearing the scene a little after 11 a.m.
Metro says single tracking will continue between the Medical Center and Grosvenor-Strahtmore Stations with delays expected.
