RTD passengers of the E and F Line hoping to get to Lincoln Station were turned around because of police activity on Wednesday afternoon.
Officials with the Lone Tree Police Department said they were called to the Lincoln light rail station to do a welfare check on a woman. When police found her, she started to walk along the tracks, then pulled a gun and shot herself.
She was taken to the hospital. Her condition is unknown at this time.
Service resumed just before 3:30 p.m.
