WASHINGTON – Water pooling in the Metro tunnel between Virginia and D.C. on Saturday added delays for Metro riders already affected by regular weekend track work, the beginning of round-the-clock work and the end of late-night trains on weekends.

A Washington Metropolitan Area Transit Authority spokesperson said Saturday that high water on one of the tracks between Rosslyn and Foggy Bottom had trains sharing a single track on the Blue Line between Arlington Cemetery and Foggy Bottom stations, and on the Orange and Silver lines between Clarendon and Foggy Bottom stations.

WMATA’s Richard Jordan said crews were just arriving to address the issue at 8 a.m., so there was no further information. There was a reported a track issue near Rosslyn Friday night as well, said Metro.

Drains and long-standing water issues are two of the problems workers are addressing during the 24/7 work zone that began Saturday on the Orange and Silver lines outside Ballston. The work is expected to affect tens of thousands of riders in some way over the next 13 days.

Metro has also been working for weeks on similar, long-standing issues elsewhere, including the Red Line. Scheduled track work affects all lines this weekend.

Much of the scheduled track work is separate from the round-the-clock work that will be performed across the system.

The scheduled track work plus the round-the-clock work mean longer waits and more crowded trains, even during rush hour.
