Athearn Genesis G18369 HO Scale EMD F45u Rebuilt Santa Fe ATSF 5956 DCC & Sound

By the early 1960’s the Electro-Motive Division (EMD) was at a big disadvantage. Their 567 engine, in use for over 20 years, had reached it’s peak at 2,500 horsepower in a turbocharged 16-cylinder version. EMD released a new 645 engine in 1966. The most powerful locomotive using this series of engine was the SD45, powered by a 20-cylinder turbocharged 645E engine producing 3600 horsepower. EMD then offered the V20 645E engine in the SDP45 in a standard hood configuration and longer frame to accommodate the steam generator needed for passenger service. The EMD SDP45 was a good passenger locomotive, but to the Santa Fe Railway it did not look the part. EMD therefore designed a lightweight “cowl” body to cover the locomotive, though it did not, as in earlier cab units, provide any structural strength, which remained in the frame. The cowl provided sleeker looks, better aerodynamics at speed, and allowed the crew to enter the engine compartment en route for diagnostics and maintenance. After sponsoring the development of the FP45 passenger locomotive, the Santa Fe requested a similar freight locomotive from Electro-Motive. Where the FP45 was an SDP45 wrapped in a full-width Cowl carbody, the new F45 was essentially an SD45 given the same treatment.

Delivered in 1968, Santa Fe’s fleet of 40 F45s was used mainly on the transcontinental line between Los Angeles and Chicago. In the mid-1970s, Santa Fe began to repaint the units and install a variety of rooftop equipment, such as air conditioners, antennas, and beacons. In 1982-1983, the F45’s were rebuilt at the railroad’s San Bernardino, CA shops. They emerged wearing new numbers in the 59XX series and were classified as “F45u / SDF45”. In 1994, 22 units were sold to Morrison Knudsen and received MKM lettering under the road numbers.
