Regular Metro service resumed at 10:30 a.m. Monday after a morning of single-tracking snarled commutes for riders on the Blue and Yellow lines.
Trains began single-tracking between Braddock Road and Pentagon City around 5 a.m. after hydraulic fluid leaked on a section of track near National Airport, the transit agency said.
Metro initially said riders should expect delays of about 15 minutes, but around 7:30 a.m., it revised that time to between 30 and 35 minutes -- and some riders said the wait was much longer.
"Add at least 45 minutes to an hour to your commute," commuter Brian Markham advised on NBC Washington's Facebook page. "Took me close to two hours to get from Springfield to Farragut West."
Alan Fontane (@All_Soled_Out) tweeted, "1hr and 50 minutes for a 25-30 min avg commute."
Not everyone ended up with a long wait, though. "It's official," wrote Tarsi Dunlop (@TarsiDunlop). "I had the smoothest commute this morning of almost anyone on Blue and Yellow -- lucked out, it seems."
On Twitter, Metro advised riders to take whatever color train was arriving and transferring at Rosslyn or L'Enfant Plaza if necessary.
Riders can expect 15-20 minute delays for the next couple of hours.
