At least 48 people have been taken to hospitals Monday in Forest Park, Ill., following a head-on collision involving two Chicago Transport Authority trains, according to the Forest Park Mayor Anthony Calderone, local media report.
The suburb of Forest Park is located about 7 miles west of Chicago.
WGN-TV reports that 11 people were injured in the incident.
The Chicago Tribune reports that one out-of-service CTA train ran head-on into another that was stopped at a Blue Line station in Forest Park around 8 a.m. CDT.
The newspaper quotes CTA spokeswoman Lambrini Lukidis as saying the crash occurred at the Harlem station. She said there were no passengers on the out-of-service train.
