ARLINGTON, Va. (AP) -- Metro says an electrical malfunction caused some smoke on the orange and silver lines at the Ballston station, and trains had to share a single track while repairs were made.
Metro spokeswoman Caroline Laurin says there was an electrical arcing incident involving an insulator on the tracks Friday morning. Firefighters were called to the scene as a precaution but have cleared the scene.
Laurin says smoke was cleared from the tunnel and station, and there was no active emergency. She says no trains were stranded during the incident.
Full train service was restored before noon Friday.
The incident is fairly routine but reminiscent of a more severe malfunction Monday that sent smoke billowing into train cars and into the L'Enfant Plaza station in Washington. One woman died Monday.
