HO GP7 with DCC & Sound, PRR #8587 Overview
When Pennsy ordered their GP7's they were still ordering locomotives with specific assignments in mind as they had done for many years with their steam locomotives. In 1953 they placed their last GP7 order. Eight of the units were set up for passenger service for use in Chicago-Valparaiso, IN commuter service, for local service between Williamsport-Buffalo, NY and in Trenton, NJ.
In 1949, EMD introduced the GP7. The basic design followed most diesel switchers with the addition of a short hood instead of an end-cab. The hoods were also full height to better accommodate the diesel engine and mechanical and electrical components.
In 1954 EMD upgraded the GP7 to become the 1,750 horsepower GP9. Externally, the first GP9s were virtually unchanged from the last GP7s. Later versions would include different louver arrangements and the last ones would come without the frame skirting. The GP9 was available with all of the fuel tank, steam generator, and dynamic brake options as the GP7, including âtorpedo tubeâ air tanks mounted on the roof.
Many railroads chose to rebuild their GP7s and GP9s for continued service. Oftentimes, it was cheaper to do this rather than purchasing brand-new locomotives.
