The Prototype:

Formed in 1971, Amtrak took over operation of most of America’s passenger trains with an assortment of old locomotives, primarily decades-old E-units. The carrier worked with General Motors Electro-Motive Division to design new passenger locomotives. The result was the SDP40F. Built by EMD from 1973–1974 for Amtrak and for a brief time they formed the backbone of Amtrak’s long-distance passenger fleet. With 150 built, the SDP40F became the “face” of Amtrak in the mid-1970s as they were found on the head ends of passenger trains from San Diego to Washington DC and from Seattle to Miami. Several were rebuilt and found a second life with the Atchison, Topeka and Santa Fe Railway in freight service.

The locomotives were loaned to Maersk for promotional events but retained their respective owner’s reporting marks. SDF40-2 6976 was the locomotive selected as the BNSF representative.
