At left, a cross section of arguably the most successful diesel locomotive engine of all time, EMD's 567 series. This colored illustration is from EMD's own manual, no. 252C, "Model 567C Engine Maintenence Manual (3rd ed. 1957)." All of the locomotives in the ad above used versions of this engine, differing in the number of cylinders and horsepowers. The success of the above types, which were VERY successful, depended upon the engine contained inside their carbodies/hoods. A two stroke engine, the 567's replaced the earlier Winton 201-A engines in EMC/EMD offerings in 1938, and remained in production through upgrades and design refinements until the 645's replaced them in 1965-66. Sturdy and reliable, they may not have offered the highest horsepower rating for locomotive engines at all times, but the whole series compiled an enviable durability and availability record. While an SD-45 at full throttle is perhaps my favorite locomotive sound, we heard many, many of these engines as well. All the yards and most of the locals used old Geeps. We loved their sound, and here's what made it. |
