Train 911 (Extra 5659 East) is passing Extra 9017 East at Tehachapi on November 21, 1977. The SP train did not have good trip out of Bakersfield and the crew has died on the law. A new crew has been called, but until this train gets moving again the dispatcher is stuck with single track from here down to Marcel.
Shoving hard on the rear of Extra 5659 East are helper engines 3335 and 3264. These units will cut loose from the train on the fly after the units get through the crossover.
Train 309 (Extra 5568 West with engines 5568, 5553, and 5051) is the next train to pass. Notice that the helper from Extra 5659 East has parked on the house track just the other side of the crossing. The crew has gone to get a bite to eat before heading back to Bakersfield. Disk 46
