Equipment Information

Burlington Northern Santa Fe (BNSF) 6976 is the last surviving locomotive of its type and the only remaining example of the first generation of diesel locomotives built new for Amtrak. It was one of 150 SDP40F locomotives built for Amtrak in the mid-1970s, but concerns about derailments led Amtrak to retire the locomotives early in favor of four-axle F40PH-type engines. This locomotive, originally Amtrak 644, was sold to the Atchison Topeka & Santa Fe in 1984 and was rebuilt for freight service. It operated for the AT&SF, and later BNSF, until retirement in 2002. Just prior to its retirement, it was painted in a unique Maersk Sealand promotional livery. The locomotive was donated by BNSF to an organization in the Pacific Northwest but soon acquired for preservation by the founder of DynaRail. That organization donated 6976 to IRM in 2025.
