The F-7 was the zenith of the "covered wagon, " or carbody-style diesel. With 3,849 units built between 1949 and 1953, the F-7 was both the most popular carbody diesel and its last hurrah. Railroads had virtually stopped ordering F-units in favor of hood units like EMD's GP9 and Alco's RS-3. The side walkways of hood units offered better access for maintenance and better visibility for backup moves, making them truly universal locomotives useful for both mainline runs and road switching.The F-unit, however, was, in Trains magazine editor David P. Morgan's words, "the diesel that did it" - retired the steam engine and changed railroading forever. The F-unit and its contemporaries were also the first standardized locomotive designs bought by American railroads since USRA steam engines.
Whereas the steam engines of most railroads had a distinctive and easily-recognized "look, " F-units were the same everywhere. But they had one great visual advantage over steam: their flat sides were like rolling billboards.Artists at EMD and the railroads responded with distinctive color schemes and, for the first time since the late 1800's, American locomotives became a riot of color in the postwar era. Externally, the F-7 was very similar to the earlier F-3.
The key spotting features that distinguished an F-7 were its stainless steel upper body grilles that replaced the "chicken wire" worn by most F-3s, and the rooftop dynamic brake fan that replaced the F-3's rectangular roof vents just behind the cab. Internally, the F-7 was also an evolution of the F-3.
While horsepower was the same, new D27 traction motors allowed the F-7 to handle a heavier load. Relive the sights, sounds, and drama of postwar railroading with this four-motored, full-scale 1:32 model. Throttle down to speeds as low as 3 scale miles per hour with any load, or roll along at the prototype's maximum speed of 102 mph with passenger gearing.
Proto-Sound 3.0 offers authentic EMD 567 prime mover sounds, a first-generation diesel horn and bell, crew and station sounds, and adjustable smoke volume. The RailKing F-7 features the same level of superb detailing that characterizes our F-3, with added-on details that include legible builder's plates, grab irons, multiple-unit hoses, rooftop lift rings, see-through rooftop fans, steam generator exhaust stack (for passenger car heating), windshield wipers, and trucks with separately-applied spring hangers, brake cylinders, and air pipes. As with the F-3, each A-unit is supplied with two sets of pilots: a fully-detailed pilot with narrow coupler opening for wide-radius curves, and a less-detailed pilot with wide coupler opening for operation on tighter curves.
