As Southern Pacific train CIPTT (City of Industy CA to Portland OR Trailers) passes us while ascending Cajon Pass, we get a good look at the Swift Trucking Roadrailers that make up this train. With the addition of a railroad truck (the steel wheels that rail car ride upon), Roadrailer trailers switch from highway vehicles to rail cars.
