The victim allegedly fled across the lanes of the Dan Ryan, and jumped a wall at 29th Street onto a northbound train where the Red Line emeerges from an underground tunnel. He held onto the train briefly but then fell underneath.
About 450 passengers were taken off two trains in the area of the accident, and service had been suspended between 47th Street to the south and Grand Avenue to the north. It was restored around 6:30 p.m.
CTA crews remained on the tracks while the fire department also investigated. The CTA removed power and called the fire department for assistance.
"We dealt with the passengers on the train. We had 350 people on two trains, one northbound and one southbound here at the scene of the accident. We have a plan in place, bringing five ambulances to the scene. "We have the mass casualty unit here. But I'd like to stress that's precautionary only," said Chicago Fire Dept. spokesman alary Langford. "Our EMS people have been talking to the people on the train as we help them onto shuttle buses. People are looked at but nobody has been transported or treated. We're here in case we're needed for that. Right now, we're assisting people as the police department starts its investigation."
The last passengers were evacuated from the trains about 6 p.m. and were being put on CTA buses parked on the Dan Ryan shoulder.
"These buses will take the passengers to another destination, so they're in the here stranded on the expressway or on the track," said Langford. "They were literally led off, and over the wall."
Langford said CTA president Ron Huberman was on the scene as well.
One passenger suffered a minor wrist injury. About 50,000 customers on average use the service at the time of the incident.
