Metro officials said an adult male in his 40s was accidentally struck by a train about 4 p.m. Monday at the Friendship Heights station, leading to major delays in the evening commute.

The station was temporarily closed but quickly reopened. Trains were single-tracking on the Red Line from the Van Ness station to the Medical Center station, but were expected to be restored to two tracks by 7 p.m. Shuttle service was available between Tenleytown, Friendship Heights and Bethesda, according to Metro.

Dan Stessel, Metro’s chief spokesman, said Metro Transit Police were treating the incident as “accidental.”

“They do not believe this was intentional,” Stessel said, noting that the man was traveling by himself. “There was no one near him at the time. We believe it was accidental.”

The man who lives in Northwest D.C. was taken to an area hospital. The incident is being investigated.
