A man jumped in front of a train in Chicago to help a woman who fell onto subway tracks.

Eddie Palacios says he was hoping the driver would see his bright orange sweatshirt and stop. Palacios was waiting for the Chicago Transit Authority's Blue Line train Wednesday when he heard people yelling that a woman had fallen. He was on his way to work as a checked-baggage supervisor for the Transportation Security Administration at O'Hare International Airport.

After he jumped, Palacios says he was thinking his orange hoodie would be visible and, if not, he could still leap out of the way. The train stopped and bystanders helped the woman.

The TSA calls Palacios a "humble hero."
