The Chicago, Rock Island and Pacific RailroadRockets were lightweight, streamlined locomotive-hauled passenger trains built by the Budd Company. These six trains were the first streamlined equipment purchased by the Rock Island, as well as being its first diesel-powered passenger trains. Four of the trains consisted of three cars each, the other two each had four cars.
The trains were articulated except for the observation cars. Later, as the railroad streamlined more trains on more routes, the list of "Rocket" trains grew.
