Metro is investigating a potential heat‑related track issue after a train derailed late Saturday morning outside College Park, prompting evacuations and service disruptions on the Green and Yellow lines.

What we know:

The incident was reported around 11:50 a.m. in the 4900 block of Calvert Road. Metro officials said 11 customers aboard the 3000‑series train were safely evacuated, and no serious injuries were reported. Prince George’s County Fire and EMS said one patient refused transport and another adult male was taken to a hospital for evaluation.

Green and Yellow line trains are single‑tracking between Hyattsville Crossing and College Park while crews assess the track condition. Metro said customers should expect delays in both directions. Yellow Line trains are operating only between Huntington and Mt. Vernon Square to reduce congestion; riders continuing north should transfer to the Green Line.

Metro is directing Green and Yellow Line customers to Route P14 for travel between Greenbelt (Bus Bay F) and College Park (Bus Bay A), and Route P10 for travel between College Park (Bus Bay F) and Hyattsville Crossing (Bus Bay D).
