The prototypes for the Rapido Trains HO Scale EMD GP38 with Extended Cab diesels are modeled after the extremely popular 2,000-horsepower locomotives introduced in 1966 with a front cab extension to allow for dual control stands as ordered by the Pennsylvania-Reading Seashore Lines and operated into the 2000s by secondary owners. General Motors' Electro-Motive Division achieved success early on, having developed and marketed a variety of 4-axle road switchers beginning with the GP7. By the mid-Sixties, EMD unveiled the latest Geep - the 2000 horsepower GP38. This was a non-turbocharged locomotive, similar in appearance to the earlier GP35. The GP38 had two radiator fans and paired exhaust stacks. The GP38 was longer than the GP35 and featured a new style radiator grille and a straighter sill and redesigned fuel tank. As with other locomotives, GP38s could be ordered with, or without, dynamic brakes, as well as a variety of other options (a few (such as this version had dual control stands), steam generators for passenger service, some railroads specified their own lighting options and short hood options). 16-645 prime mover and a D32 direct current (DC) generator, similar to all the other locomotives produced previously by EMD. The push to higher horsepower, however, necessitated larger DC generators and in 1971 EMD introduced a new option for the GP38 - an AR10 alternating current (AC) alternator in place of the generator. This was a solution to the space problems encountered by the large generator, because alternators were smaller, yet offered the same electrical capacity. And thus was born the GP38AC, which are externally identical to the GP38. The GP38 was a popular engine, filling a niche for railroads requiring a locomotive for lighter duty and for use on trackage that was often not for high-speed mainline trains. As such it was purchased for a number of shortlines and a small number of industrial users. As a number of Class I railroads operate a lot of branch lines, the GP38 was also popular with these larger railroads as well. The HO Scale EMD GP38 is loaded with roadname-specific details including the extended cab and features appropriate truck sideframes, headlight placement, dynamic brake placement, a operating headlights, class lights and auxiliary lights. This models is equipped with an ESU LokSound V5 sound and DCC decoder and features dual flywheels and magnetic knuckle couplers. EMD GP38s are part of the extensive line of Rapido Trains HO Scale locomotives.
