All CTA trains were running Monday morning after violent storms halted service on the Blue, Red and Brown lines overnight, knocking an aluminum canopy onto the third rail near the Medical District station, toppling a tree near the Armitage station and tossing debris onto the tracks near the Sedgwick station.



No injuries were reported in any of the incidents.



The Paulina Street entrance to the Blue Line's Medical District station at 430 S. Damen Ave. remained closed as crews worked to repair the canopy over the pedestrian ramp that leads to the station, according to CTA spokeswoman Catherine Hosinski.



The concrete ramp remains intact, she said, but a part of the metal canopy was torn off during the storms and fell onto the tracks around 7 p.m. Sunday. Fire officials said it appeared the walkway or an area nearby was hit by lightning, but CTA officials said they were still investigating and added that it was possible high winds were the cause.



A video taken by a motorist show flashes and sparks at the station to the west and a blinding flash where the canopy apparently hit the electrified third rail.
