Illinois State Police received a call about a crash about 12:40 a.m. A motorcycle was traveling south at a high rate of speed in the Interstate 94 express lanes when it hit a concrete median, police said.
A 40-year-old Country Club Hills man was driving the Harley-Davidson motorcycle. His passenger was a 55-year-old Country Club Hills woman.
Both the motorcycle's riders were thrown onto the Red Line tracks at 47th Street.

Witnesses said they saw a dark-colored vehicle hit the motorcycle and keep driving, but state police could not confirm the possible hit-and-run.
Red Line service began running again about 7:30 a.m., bypassing 47th Street. All Red Line service resumed just after 9 a.m.
