HO GP40-2 Locomotive, SP 'Kodachrome' #7672
$204.34
By the end of the 1970’s, SP was in need of high-speed motive power for their hot shot trains. They placed their first order of 20 GP40-2s (SP 7608-7627) from EMD with order number 776071 in 1978. Being rather late to the table for this model, SP seemed to be impressed and ended up ordering 4 more batches including some for their subsidiary, Cotton Belt. SP-specific features include: 4-hole jacking pads, Nathan P3 horns, large “L” front window, and full SP light packages on both ends. From SP’s 3rd order of GP40-2’s, we are pleased to announce their only GP40-2 “Kodachrome” repaint, SP 7672. From the failed Santa Fe/SP merger of 1986, many units were repainted into this bright scheme in anticipation of a merger that was ultimately denied.
PROTOTYPE AND BACKGROUND INFO:
By the early 1970s, many first generation diesels were reaching the end of their service lives. One of the most common replacement locomotives became the GP40-2. EMD began production of the 16-cylinder, turbocharged, 3000 horsepower engine in 1972. These locomotives were developed for service where higher horsepower and faster service were preferable. A major feature for the GP40-2 was the introduction of the “dash 2” modular electrical cabinet. For more than 40 years, the GP40-2 has worked main line freights, locals, switching jobs, yard service, and helper service. Many remain in service today.
