Union Pacific Railroad tallied 219 EMD GP9s by the mid 1950s. Interested in a version built without control cabs, they placed an order with EMD for GP9B locomotives. All GP9B locomotives were built in the United States between February, 1954, and December, 1959. UP was the single largest owner of the GP9B, with a total of 125 units on the roster. The units were numbered 130B-204B and 300B-349B.

PROTOTYPE INFO:

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 “torpedo tube” air tanks mounted on the roof. 

Many railroads chose to rebuild their GP7s and GP9s for continued service. Often times, it was cheaper to do this rather than purchasing brand-new locomotives.
