Green Line trains are no longer single tracking after an earlier, track-related delay between the Greenbelt and College Park Metro stations.
A WMATA spokesman said a loose third rail cable on the track near College Park, Maryland led to single tracking around 5 a.m. Tuesday.
Trains were no longer single tracking as of 6:15 a.m. Expect residual delays in both directions.
