Inbound train no. 102 collided with the empty vehicle about 6:25 a.m. near Palatine Road, according to Metra spokeswoman Meg Reilly.
It appeared that the car, which wasn’t near a rail crossing, had been parked too close to the tracks, Reilly said.
No injuries were reported on or off the train, she said.
In a service alert, Metra said it was moving passengers from the affected train onto train no. 108, which Metra said was operating up to 50 minutes behind schedule.
