UPDATE 3:25 p.m.: The evacuated train didn't have a fire on it despite what Metro e-alerts may have shown, according to Montgomery County's Fire Department. Instead, the train's brakes were smoking, said Assistant Chief Scott Graham. The smoke then filled the station, causing the shutdown. Fire crews opened up two air shafts to ventilate the station, he said.

3:12 p.m. Red Line trains are sharing a single track near Forest Glen after smoke on a six-car train forced an evacuation of the train, then a shutdown of the whole station.

Then at 2:15 p.m. the station was shut down because of the smoke, she said. Trains were sharing a single track between Silver Spring and Wheaton stations as of 3 p.m., but were not stopping at Forest Glen. Shuttle bus service is ferrying riders to the adjacent stations.
