A 19-year-old woman was in critical condition after being hit by a Red Line train Thursday afternoon at the Roosevelt station.
Paramedics were called to the South Side station about 1:45 p.m. for a woman who fell on the tracks and was struck by an incoming train, Chicago police said in a statement. She was taken to Northwestern Memorial Hospital.
A law enforcement source said the incident appeared to be a suicide attempt.
While crews responded, Red Line trains were rerouted to elevated lines between Fullerton and Cermak-Chinatown, according to the Chicago Transit Authority.
Trains were initially halted to Roosevelt at 1:45 p.m. due to a medical emergency on the tracks, and were rerouted less than 5 minutes later, the CTA said in a service alert. Trains resumed normal operations about 2:20 p.m.
