ET44C4 GE Evolution Series ET44C4 locomotive is an industry breakthrough, delivering a modern and efficient alternative to the DC-powered locomotive models. Compared to GEDC EVOs and Dash 9 locomotives, the ET44C4 model powers only 4Â axles rather than 6 while maintaining the performance of a DC locomotive, allowing railroads to enjoy savings both in locomotive price (compared to the ET44AC locomotive model) and operating cost

(fewer traction motors to maintain). One of the ET44C4 locomotive technology breakthroughs is a unique feature, the Dynamic Weight Management (DWM) System, that continuously monitors traction performance. Whenever additional adhesion is required, the DWM system automatically transfers some of the weight from an idler axle to the AC-powered axles without operator assistance.
Reduces locomotive and operating costs with 4 vs. 6 powered axles
