       The Seaboard Air Line operated eight passenger-equipped GP7's, Nos. 1704-1711. The Pullman Green-and-yellow Geeps were built in 1950, each carrying 800 gallons of fuel and 800 gallons of water. All lacked dynamic brakes and the roof-top air reservoirs found on passenger-equipped GP's of other railroads. What may be unique among GP7's is the "fairing" atop the leading edge of the cab roof.

       Modelers can begin with the Athearn GP9 (really a GP7) by removing the dynamic brake blister and winterization hatch. A new rear roof panel should be fabricated (use .010" sheet styrene) and new radiator fans installed. Cutting away some of the skirting above the fuel tank will enhance the appearance of your locomotive, although the prototype locomotives were delivered with fuel tank skirting as provided with the Athearn model.

       The addition of commercially available detail parts will further assist in setting your model apart from those of the out-of-the-box variety. The Bill of Materials lists many readily available detail parts; where competing parts are offered by more than one producer, all are listed. Although the photos don't show the "back porch" to its best advantage, two m.u. stands and a drop step, along with the full complement of detail items found on the front pilot, are fitted there too.

       To paint the model, use Pullman Green as the basic color and a mixture of three parts Reefer Yellow with one part Reefer White for the light yellow band. Finish with Microscale decal set No. 104. Send us pictures of your model when completed!

    Dave Jones Seaboard also had s/g equipped GP-7s #1745-1769. While the earlier units had the smoke-lifting fairings along the cab edge, the later units did not. Don't think these units were commonly used on pssenger trains but they did on #25/26, the "Boll Wee...  more
