About 30 people were safely evacuated from a Blue Line train that had a power failure Tuesday afternoon on the Northwest Side, according to the Chicago Fire Department.
Fire crews were called about 2:51 p.m. for a stalled train between Central and Harlem avenues, according to CFD spokesman Larry Merritt.
Trains were initially standing near Harlem due to a track condition, the CTA initially said at 2:37 p.m.
Service resumed normal service with delays about 5 p.m., the CTA said.
A spokesperson for the CTA did not immediately have details about the suspension.
