Santa Fe 4-unit lashup with a freight train westbound at Joliet, Illinois, 1975

With an SD45-2 (these had a 20-cylinder prime mover that produced 3600 hp) on the point westbound near the tower at Joliet. The train pictured may be the famed Super-C, a hot TOFC train that ran between Chicago and the west coast. The Santa Fe ran parallel to the GM&O at this spot; the train would cross the Rock Island within seconds.
