Description
Railroad Short Name: NW
The arrival of the U25B in 1959 and the interest it drew from the railroads meant EMD would revamp its designs to meet the challenge from the newcomer. The basic GP7/9/18/20 platform was stretched slightly to allow for a larger fuel tank for increased range and tractive effort. Having proven the advantages of turbocharging in the predecessor GP20, the turbocharged 16-567 prime mover was retained, though receiving a slight boost to 2,250hp. The biggest change came in the carbody design, which featured an all-new main electrical cabinet at the rear of the cab, which drastically changed the cab height and profile in comparison to the GP20. EMD would also introduce a centralized air system as well, with an inertial air intake and filtration system to provide clean pressurized air to the locomotive. And in an unusual twist, EMD engineers would turn to parent GM’s automotive styling department to help blend all of these new features into the carbody.
The result of all of these design features was … the GP22. With its model number falling in line with its horsepower rating and EMD’s numbering system at the time, this new demonstrator locomotive for 1961 looked like no other in the EMD lineup. The taller electrical cabinet, combined with the styling input from GM, created a “humpback” from the cab back, extending into the inertial air filter compartment, ending in fairings that straddled the roofline and concealed optional dynamic braking equipment. Coming with a low-short hood as standard, the cab face featured a “vee” profile, offering improved visibility and reduced glare for the crew. The cab front roofline was set back in a unique brow, and the flat cab roof rolled gracefully down on each side into a stepped fairing, all blending into the long hood roofline.
The demo unit, numbered 5629, quickly set out to prove its capabilities and features to the railroads. But before long, EMD would re-designate its new general-purpose unit the “GP30”, mainly as a marketing move, the rationale being the model number “30” being greater than the “25” of the competition. They would also tout “30” design features and improvements over previous models. This change, along with a return trip to LaGrange for a new demonstrator paint scheme and some styling tweaks to the carbody that would give it the definitive GP30 “look”, would set the stage for the GP30’s arrival on the railroad scene.
