Three SF30C's and one C40-8W near the New Mexico, Arizona border. I'm not sure of the exact location.
Santa Fe GE/ATSF SF30C 9568, SDP40Fr 5267 and SF30C 9542 at Cleburne, Texas in September 1987.
Last batch of SF30Cs were yellow, but 9568 sports the then experimental flange lubricating system, evidenced by the tank just behind the conductor's side.
