This is the GP7 we were riding back in. It says so right above the GP7 sign in the cab. Thanks Ameen, good thing I'm a sharp eyed camera guy. Western Pacific 713. Niles also has another GP-?. that's beautiful. I'm not sure what model it is so I’m keeping my mouth shut. Maybe Tom knows.

Note: This time I looked up the SP engine. It’s an SD9.
