T.L. VanSlyke, local chairman of Div. 624, was running the 6717 and a train of empties to the East Decker coal tipple to await an automated loading.
Burlington Northern bought a large number of these (one source says 186 total) 3,000 hp. General Electric locomotives in the late 1960s-early 1970s, many of which worked in the Powder RIver Basin hauling unit coal trains. The U30C was among GE's most successful 'Universal-Line' designs, a type that originated with the U25B in 1959. The U30C was aimed a competing with EMD's successful SD40/SD40-2 line, also rated at 3000 hp. The U30C, as its designation implies, is a C-C type, or in layman's terms it has two six-wheel trucks with all wheels powered. It uses standard GE equipment: 16 cylinder 7FDL diesel engine (derived from the Cooper-Bessemer design) ; and GE752 traction motors. By Brian Solomon
