Wallace W. Abbey (1927-2014) spent his career as a railroad journalist and public relations executive, primarily in the Upper Midwest. His combined writing and photographic skills documented well the dynamic railroad landscape from the 1940s through the 1980s. Although Wally never worked for the Santa Fe, it was his favorite railroad, in part because of its 100-class diesel-electrics.
