From Metro: “A second cracked rail was discovered at 1:50 p.m., outside the Medical Center Metrorail station on the Red Line in the direction of Glenmont. While Metro crews make repairs, Red Line trains will share one track between the Grosvenor-Strathmore and Friendship Heights Metrorail station. Riders may experience delays up to 30 minutes. Shuttle bus service will be established between the Grosvenor-Strathmore and Friendship Heights Metrorail stations.” Given that the Red Line is already sharing the same track between Fort Totten and Takoma on the other arm of the line, looks like no joy this evening once again for Red Line commuters.
