Many Monday morning commuters on the Red Line, Metro’s busiest, encountered unusually crowded platforms, packed trains and delays while the transit authority requested attention for a sick passenger at Van Ness.

Washington Post strategic projects editor Emilio Garcia-Ruiz, who was on the scene, reported shortly before 9 a.m. that the woman was sick on the floor of a train and “was pale as a ghost.”

According to a later tweet from Metro’s official account, @wmata, “The earlier Red Line delays were result of unconscious/unresponsive woman on a train. EMS responded and transported her to hospital.”

Because Metro is based on a two-track system, trains in both directions shared a shingle track around the train that was stopped at the platform. That caused delays to ripple along the line and delayed many commuters, setting off a chorus of complaints.

Brian Anderson, Metro’s social media manager, responded to inquiries from passengers via the official Metro Twitter account that “we can’t move until medical personnel arrive. Capacity limited by half, so we move trains through the available space ^BA.”

Red Line customers also had to endure waits associated with a train malfunction at Union Station, while Orange and Blue line trains were delayed due to a disabled train at Farragut West.

About 11:30 a.m. Metro warned its Green Line passengers to expect delays “due to a sick customer aboard a train at” Fort Totten, as trains single tracked between Georgia Avenue and Fort Totten stations.
