Metro says the track repairs have been finished at Stadium-Armory, but delays continue in both directions.

Metro spokesman Dan Stessel said the cause of the issue was unknown.

“The source of smoke was the ‘boot’ portion of a power cable,” Stessel said in an email. “Third rail power was taken down, resulting in single tracking, to make repairs.”

The Federal Transit Administration, which took over Metro safety oversight last year, is investigating the incident, according to spokesman Steven Kulm.

Single-tracking continues on stretch of the Orange, Blue and Silver lines that has been prone electrical problems all week.

Orange Line trains were sharing a track between Stadium-Armory and Cheverly, while Blue Line trains were single-tracking to Addison Road.

Silver Line trains were terminating at Ballston-MU. Metro said the issue was a power problem. Earlier this week, rail service was disrupted when a test train made “undesired contract” with third-rail infrastructure that contractors had been working on, according to Metro.

Metro spokeswoman Morgan Dye said the issue initially was reported as an arcing insulator but was later determined to be a smoking boot, a type of railroad connector assembly.

She said D.C. Fire and EMS initially responded but was clearing the scene by 3:45 p.m. In addition to the single-tracking on the Orange and Blue lines, the Silver Line is operating between Wiehle-Reston East and Ballston-MU station. Metro said to expect crowding and delays of up to 20 minutes because of single-tracking and congestion downtown.

Metro trains are sharing a track Wednesday afternoon on a stretch of the Orange and Blue lines that has been problematic all week. Orange Line trains are single-tracking between Stadium-Armory and Cheverly, while Blue line trains are single-tracking between Stadium-Armory and Addison Road.

Metro said crews were working to resolve a track problem.

Earlier this week, two fires occurred in the same area on the same day. Electrical problems Monday morning stalled a train for about eight hours — leading to extended single-tracking in the morning, while an afternoon track fire led long delays during the evening rush.
