Guts and Hustle Muscle in Montana
It's been a few years now, but there was a time not so long ago when solid sets of 20 cylinder diesel locomotives could be found pouring their guts out doing what they always did best. Even further back than that, these beasts could be found on railroads across the entire U.S. When these pictures were taken the year was 2005 and there were but a few remaining daily users. The SD-45 (and its close relative, the F45) was quite a machine, and Montana Rail Link used them as they were always intended, even in their fifth decade of service. "Hustle Muscle" was the nickname applied to first SD-45, owned by the Great Northern. Other nicknames have included flare-45 because of the unique flared radiators at the rear of the unit. These flared radiators were necessary to provide the extra cooling capacity for the large 20-cylinder diesel that EMD installed under the long hood. The 20 cylinder diesel made only a brief appearance in the EMD lineup and sales of the 45 series
