GP7
The EMD GP7 is a four-axle ( B-B) diesel-electric locomotive built by General Motors Electro-Motive Division and General Motors Diesel between October 1949 and May 1954.Pinkepank, Jerry A. (1973) pp. 53 Power was provided by an EMD 567B 16-cylinder engine which generated . The GP7 was offered both with and without control cabs, and those built without control cabs were called a GP7B. Five GP7B's were built between March and April 1953. The GP7 was the first EMD road locomotive to use a hood unit design instead of a car-body design. This proved to be more efficient than the car body design as the hood unit cost less to build, was cheaper and easier to maintain, and had much better front and rear visibility for switching. Of the 2,734 GP7's built, 2,620 were for American railroads (including 5 GP7B units built for the Atchison, Topeka and Santa Fe Railway), 112 were built for Canadian railroads, and 2 were built for Mexican railroads. This was the first model in EMD's GP ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GP10
The EMD GP10 is a diesel-electric locomotive that is the result of rebuilding a GP7, GP9 or GP18. The Illinois Central Railroad had three separate rebuild programs to upgrade their old EMD GPs and GPs that they had purchased from equipment dealers such as Precision National Corporation in Mount Vernon, Illinois. The first was the GP8, second the GP10 and third the GP11. All were rebuilt at IC/ICG's Paducah Shops in Kentucky. Core units for the GP10 program were from IC/ICG GP7, GP8, GP9 and GP18, B&M GP9, B&O GP9, CRR GP9, C&O GP7 and GP9, D&RGW GP9, DT&I GP7 and GP9, FEC GP9, GTW GP18, P&LE GP7, Potlach Forests Inc. GP7, QNS&L GP9, RDG GP7, St.J&LC GP9, SLSF GP7, SP GP9, SSW GP7, and UP GP9B. Two IC GP9s were rebuilt to GP10s and sold directly to the Ashley, Drew and Northern Railway. Nine Alaska Railroad GP7s were rebuilt to GP10s by Paducah, and renumbered 1801-1809 (these rebuilds received EMD angled cabs but kept their AAR Type B road trucks from Alco ...
