After the merger, BNSF continued to use their remaining GP7U’s in branchline and secondary service. However, many years of service began to take their toll on the appearance of the units. They often exhibited faded coats of Santa Fe blue & yellow, various types of BNSF patch lettering, and replacement parts. #1356:

The Chicago and North Western’s Oelwein shops were known for turning out a variety of rebuilt locomotives. 74 GP7s and 55 GP9s were rebuilt between 1971 and 1981. As part of the process, dynamic brakes (if any) were deactivated, and many units received chopped noses. Engines and electrical equipment were also overhauled. Starting in the early 1980s, these units were painted using a lighter shade of yellow known as “Zito Yellow”, as depicted on our models.

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 boats.” 

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.
