Atlas Union Pacific SD60M
This is a test shot in which a shorten piece of code 80 rail was used as a gap filler/chassis frame in the space between the truck and under body of the model. It's not really practical as is because the it will restrict the movement of the truck on uneven track. Must admit I kinda like the look. I will have to either file the piece down or just use code 70 or 55 track piece as suggested by the modeler who inspired this project.
