Chicago’s Blue Line trains were halted Sunday night after lightning struck the tracks and caused a pedestrian area to collapse, authorities say. The incident occurred around 7 p.m. at the Illinois Medical District station, according to the Chicago Transit Authority. Lightning apparently caused the canopy above a pedestrian ramp to collapse onto the platform and the tracks. There were no injuries, but one of the trains had to be evacuated. As of midnight, the Blue Line was running again but bypassing the Illinois Medical District station, where crews were still working to clear the area.
