CHICAGO — Parts of the Green Line and Pink Line were closed for hours Tuesday as a man ran for two miles on the "L" tracks, threatening to jump, officials said.

Emergency workers inflated the Fire Department's "jump bag" under the man, hoping to save him if he jumped. He was eventually talked down, and trains are now running.

Authorities say he ran on the tracks for two miles before he was cornered between the Ashland and Morgan stops.
