A problem with the third rail caused major delays Tuesday morning on the CTA Blue Line near northwest suburban Rosemont.
The problem was reported at 7:15 a.m., CTA spokesman Steve Mayberry said. Trains were only operating between O’Hare and Rosemont, and between Rosemont and Forest Park, with passengers forced to switch trains at the Rosemont station.
Normal service on the Blue Line resumed about 11 a.m., but residual delays may occur, according to a CTA alert.
The problem involved the third rail on the track, but further details were not immediately available, CTA spokeswoman Lambrini Lukidis said.
