The Quad Cities Rocket was a named passenger train of the Chicago, Rock Island and Pacific Railroad. It operated on a route between Chicago and Rock Island, Illinois. It was a remnant of one of the Rock Island's premier trains, the Rocky Mountain Rocket. That train's route had been cut back to Omaha in 1966; after a year without a name, it was renamed The Cornhusker. In 1970, the train took its final form when its western terminus was cut all the way back to Rock Island.
