EJ&E Baldwin/EMD #909, Joliet, Illinois, February 13, 1965, photo by Chuck Zeiler. The V-12 567C was normally rated at 1200 hp, but those installed in the EJ&E Baldwins could not be used at maximum capacity. The 567C produced its rated horsepower at around 800 rpm, but in the EMD/DT-6-6-2000's, the diesels were mated to the original Westinghouse main generators, which were designed to turn at a maximum of 625 rpm. Turning the generators any faster resulted in "lots of fireworks" (a.k.a. flash-over) inside the hood, so the EMD diesels had to be slowed down. This was not without problems; at constant low speed the diesels suffered from poor lubrication and overheating. Eventually speed settings to suit the diesels and generators were found and the repowering by EMD was considered a tolerable success. The EMD repowered units were renumbered in the 900 series.
