Metro says a train that became disabled while testing tracks after a small track fire is causing delays on three lines in southeast Washington.

Metro spokesman Richard Jordan says a small fire broke out the tracks early Monday between the Minnesota Avenue and Stadium-Armory stations. He says that fire was put out using a fire extinguisher.

Jordan says a train testing whether the track was ready to open after the fire and weekend track work became disabled outside Stadium-Armory.

Jordan says trains are using just one track through that area on the blue, orange and silver lines. He says the delays will continue until the train can be removed and another train can test the tracks in that area. He says it's not clear how long that will take.
