Riders who use the Blue/Orange/Silver lines should expect delays of 20-40 minutes and crowding on platforms and trains during today’s afternoon rush hour while workers repair the track, according to a Metro news release.
Metro management arranged to have single-tracking between Smithsonian and Federal Center Metro stations so workers can replace loose rail fasteners near Smithsonian station, Metro spokesperson Morgan Dye said.
Trains started single-tracking around 11 a.m. Tuesday.
Track inspectors noticed the defect during a routine walking track inspection, according to the release. Riders who take the Blue Line to or from Virginia south of Pentagon City station should consider the Yellow Line.
Riders traveling between D.C. and Arlington stations on the Orange Line can ride the Metrobus 38B instead of taking the Metro.
The single-tracking will extend between Federal Center SW and McPherson Square to allow for repairs, after rush hour is over.
The delay hearkens back to the Aug. 2015 derailment near Smithsonian station, which caused extensive delays on all three lines for the morning and afternoon rush hours.
