|AT&SF SD45-2 5691 ( far right ) at Corwith Yard in Chicago, Illinois on an unknown day in September 1979, Kodachrome by Chuck Zeiler. Built in May 1973 ( c/n 72642-5 ), it was rebuilt at San Bernardino in May 1986 to SD45-2u 5817. It was painted in the SPSF Kodachrome paint scheme and assigned number 7717 so as not to conflict with SP's numbers. I don't know how long it was 7717, if it ever was. It was repainted back to standard AT&SF blue sometime before January 1991, became BNSF 6467 on November 25, 1999, and it appears it now resides in South America.
