Update 12:18 p.m.
At least 33 people were taken to local hospitals Monday when an out-of-service Chicago Transit Authority train crashed head-on with another train stopped at a Forest Park, Ill., suburban station west of Chicago, local media report.

CBS 2 reports that police are investigating the possibility that somebody hijacked an out-of-service CTA train and sent it crashing into the second train.
Suspicion of foul play was raised because the out-of-service train had far fewer cars than a normal rush-hour train, was on the wrong tracks and had nobody at the controls when the crash occurred.
Although police are treating the accident as a crime scene, a CTA official tells CBS that there is no indication of criminal activity and that the CTA is working under the theory that the accident is due to a mechanical malfunction.
The collision occurred at the Harlem station on the Blue Line in the town located about 7 miles west of Chicago.
The Tribune reports that the crash occurred around 8 a.m. CT.
