Passengers had to be offloaded from a Red Line train and one was hospitalized after two cars derailed Sunday afternoon.
A service warning from the Chicago Transit Authority indicated a mechanical problem on a southbound train at the Sheridan stop at about 3 p.m. After the cars became uncoupled between Wilson and Sheridan, the Chicago Fire Department responded to a call at the Wilson stop.
After checking on passengers and transporting one to Weiss Memorial Hospital in serious condition, operations were turned back over to CTA, according to a CFD spokesman.
Shortly after 5 p.m., CTA stated indicated on X, (formerly Twitter) that while service had resumed, Red Line trains were running with residual delays.
In an email Sunday evening, the media relations department at the CTA said the agency is still investigating details about the cause of the defect.
