WASHINGTON, D.C. -- A portion of Metro’s Red Line will be single-tracking over much of the next four days as crews look to repair damage being blamed for some recent incidents.
"Two distinct incidents have occurred," Metro General Manager Paul Wiedefeld told the Metro Board of Directors when announcing what he called a "maintenance surge."
"One, obviously, was the one we had Saturday which was a foreign object, that the train came in contact with or something occurred in that area. That’s still under investigation, but we did eliminate a power issue related to that, in terms of any power cables or anything of that sort. The other issues, which we’ve actually played out the last few days is arcing insulators," he said.
Crews will be working between the Van Ness and Medical Center stations.
Single-tracking will take place between those stations between 10 a.m. - 3 p.m. and 8 p.m.-station closing on Thursday and Friday, and all day Saturday and Sunday.
Riders can expect delays of up to 20 minutes.
Wiedefeld said this section of the Red Line was troublesome as a lot of moisture seeps into the tunnels.
"We will basically be replacing insulators, if they need to be replaced. Doing more leak mitigation, in terms of moisture. Drain cleanage, there’s a lot of both, again, moisture and soil that gets into that area. So there’s mud and trash removal. Third rail repairs if they’re needed."
