The story titled, Captive cowls, shares how two of an original fleet of 60 cowl-bodied former Canadian National SD50Fs wound up in a small southwest Montana town. The needs of Montana Limestone’s operations dictated the need “to purchase heavy-duty, high-horsepower, six-axle locomotives when loading and prepping the unit trains. The former Canadian National SD50Fs fit the bill,” according to the story.
“In 2009, Dakota, Missouri Valley & Western, which also provides rail service to Basin Electric facilities, acquired eight CN SD50Fs, and inspected, rehabilitated, and painted two for MLC. That pair and four DMV&W units are the sole operating survivors of CN’s original fleet of 60 SD50Fs. Montana Limestone’s are the only ones employed exclusively for switching.”
