ATSF answered the need for hump power at their new yard in Barstow by creating the unique CRSD-20 combo, contrived by applying an EMD engine to a retired Alco RSD-15 Alligator. Geared very low, they had to be towed to their assignment. Here the last one 2902 (later 1302) is heading east. Hey, it's not sunny California all the time!
