A train was damaged when it hit a piece of track equipment between the Wheaton and Glenmont stations, but no one was injured, Metro said.
A Red Line train with passengers was leaving Wheaton around 11 a.m. Thursday when it hit the equipment, damaging the left side of the train, Metro spokeswoman Taryn McNeil said. McNeil did not know what kind of equipment was hit.
The train was able to back up into the station to allow passengers to get off.
Trains ran on a single track through the area for about an hour while the area was cleaned up. Regular service has since resumed.
