Introduced in 1985 as the refined replacement for the five-year-old 50-series locomotives the GP60 (and sister SD60) represented a significant leap in locomotive design for EMD. Incorporating computer technology to control locomotive operation and onboard diagnostics the 3800 hp GP60 just may be the "ultimate" geep. Designed for hi-speed intermodal traffic this locomotive could be found on the major transcontinental carriers in the service for which they were designed. In fact a variation of the GP60 became so associated with the Santa Fe in the early 1990s it came to represent the best that railroads had to offer in quality service.
