Delivered in 1968, Santa Feâs 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 F45âs were rebuilt at the railroadâs San Bernardino, CA shops. They emerged wearing new numbers in the 59XX series and were classified as âF45u / SDF45â. In 1994, 22 units were sold to Morrison Knudsen and received MKM lettering under the road numbers.
