WASHINGTON — An arcing insulator near the Federal Center SW station led to delays on Metro’s Orange, Blue and Silver lines for about a half-hour on Thursday morning.
The arcing happened shortly before 7 a.m. and led to a small fire, which was quickly extinguished. Trains were held in both directions for about a half-hour.
Metro said normal service had resumed a little after 7:30.
It’s at least the third arcing incident for Metro in the past few weeks.
