Santa Fe SD40-2 5114 leads a mixed quartet of power (SD45-2, SD26 and U36C) through Walong ... perhaps better known as the Tehachapi Loop! Just beyond the right edge of the photo, under the piggyback cars, is the tunnel that the rear of the train is passing through ... and underneath the front portion of the train. The Loop was constructed to gain maximum elevation in a minimum of space.
