General Electric (GE) is one of the world's leading conglomerates. Their locomotive building business consisted mainly of industrial units and components for other manufacturers. This changed when they entered the road locomotive business with 1959's U25B. From that time on, GE has supplied locomotives to railroads around the world, and Conrail and its predecessors were no different. CR inherited a fleet of GE's "U-boats", and purchased numerous dash 7 and dash 8 models new.
