NEW ELECTRIC LOCOMOTIVES
Two new U. S. electric locomotives, designed for heavy-duty freight service, have the most modern thyristor control and a number of novel features. In terms of tractive effort and its wide range of horsepower, one model is believed to be the most powerful locomotive in the world. This article covers the major features of these new electric locomotives and also provides some comparisons with modern-day diesel-electric locomotives in the U. S. The GM-6C model is rated at nominally 6000 diesel equivalent hp, and utilizes a Co-Co truck arrangement. The GM-10B model is rated at nominally 10,000 diesel equivalent hp, and uses an unusual Bo-Bo-Bo truck arrangement, new for the U. S. For each locomotive, a description is given of the carbody, trucks, traction motors, auxiliary equipment and power transmission and controls. Performances are reported. Maintenance costs are claimed to be 64% that of a diesel electric locomotive. Power is picked up by pantograph.
