MTH ELECTRIC TRAINS

When EMD introduced the 3,000 hp GP-40 in 1965, they had essentially doubled the power of the first "Geep," the 1,500 hp GP-7 that was the builder's standard general-purpose road switcher until 1954. The GP-40 was the first of the Geeps to have a 645-series engine rather than the 567-series prime mover EMD had relied upon for years. The GP-40 represented a remarkable increase in power over a short time, but it was not trouble-free. The 3,000 hp was almost more than the engine could handle. With only four axles and the barely adequate wheel-slip control systems then available, the GP-40s had some adhesion problems. This was corrected with an improved electrical control system. M.T.H. is pleased to introduce the GP-40 to our Premier line in the markings of the Chicago NorthWestern, Seaboard, Western Maryland, and Western Pacific railroads. This rugged and powerful road switcher is ready to serve your railroad without any of the adhesion problems that marked the prototype. Pull-out fact: EMD had tested the first 645 engines in the very limited run GP-39, but the engine was then rated at only 2,300 hp.
