GP60-series locomotives EMDs GP60 model was the last of a series of four-axle locomotives built with ever-increasing horsepower, designed to lead a railroad’s priority trains.

Smoking Santa Fe 3460 Hudsons steam locomotive with train

Santa Fe 3460 Hudsons had an impact on the railroad much larger than their class size would indicate. Mention the Hudson steam locomotive and the name “Santa Fe” likely won’t come up right away.
