Overview
Serious efforts to use AC (Alternating Current) diesel-electric engines began when General Motors introduced its 4000-horsepower SD-60MAC in 1991-92. While the AC power increases an engine's adhesion, allowing it to start far heavier trains than a DC-powered locomotive of the same horsepower, the heavier load prevents AC-powered engines from reaching track speed. To solve that problem, locomotive builders have raced to design and deliver AC engines with ever-larger horsepower. SD90-MAC's use a whopping 6000 horsepower to power their freight down the rails.
