In 1967, Great Northern introduced a new paint scheme, consisting of blue, white, and dark grey-green. Known as the Big Sky Blue scheme, it took its name from an unofficial nickname for the state of Montana. Several of GN’s GP9 locos received the treatment as depicted here.

In 1970, GN was merged with the other Hill roads to form Burlington northern; however, the Big Sky Blue painted units survived for some time after with a simple BN patch.

PROTOTYPE SPECIFIC INFORMATION
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.
