We are very concerned to discover on the morning of Tuesday, May 31, 2016 there were multiple reports of multiple arcing insulators outside of the Rosslyn station on the New Carrollton/Largo track just beyond station limits. Initial reports indicate this condition was first reported at about 6:51 AM and again at about 8:15 AM. During the second report at 8:15 AM, three insulators were reported and that they would be good until after rush hour.
We are still reviewing this event (16-0165), however we find that keeping this track in revenue passenger-carrying service with visible signs of arcing completely unacceptable. Service should’ve been immediately suspended for the approximate 20 minutes needed to replace the insulators.
