Introduction

Athearn Genesis G18290 HO Scale EMD F45u Rebuilt Morrison Knudsen Corporation MKCX 5957 DC

By the early 1960s the Electro-Motive Division (EMD) was at a big disadvantage. Their 567 engine, in use for over 20 years, had reached its 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.

During the mid-1990s, Santa Fe sold off a batch of F45s to Morrison Knudsen with a simple painting over of former owner markings to get them back into lease service. MK was no stranger to the locomotive rebuilding and leasing market. Santa Fe was able to lease them back on short term lease agreements. They could also be seen on UP and SP trains when they were needed.
