The Super C was Santa Fe's hottest piggyback train. It began operating on January 17, 1968. It is sprinting west with a short piggyback train under the command of four SD45s on February 19, 1974. The last run of the Super C was on May 4, 1976. Those are snow clouds moving in from the north. By the next morning our camp site at Adamana was covered in snow and my brother and I wondered if we would be able to drive out to the main road. Pictures above are on disk 71.
