In November '88, prior to ordering a batch of wide cab EMD GP60M's with desk top controls, a first for Santa Fe, the railway borrowed an CN wide cab SD60F with desk top controls for demonstration and crew input. A set of wide cab power was assembled with the CN as leader and it was arriving Santa Fe's Hobart diesel service facility at Hobart Yard in Los Angeles.
The EMD SD (special duty) series are a strong and reliable kind of locomotive which still serve America's rails today. They have proved themselves reliable by clocking in several million miles of freight service over several decades.
Freight Cowls are standard locomotives that have a hood that extends the full width of the locomotive. Sadly, most Freight Cowls have been retired, but a few still run on short lines.
