CNW 4153 started out as an undecorated Proto 2000 GP7 with sound.

This is a former Rock Island unit that went through a capital rebuild before it came to the CNW after shut down.

To model the unit, I started by fabricating roof access panels from styrene. Also, I fabricated the open spark arrestors using plastic and left over photoetch material. I replaced the stock plastic grab irons with Tichy brass grabs. I fabricated and soldered a stand to a new Details West horn and added an antenna and beacon to the cab roof. Eyebolts were added.

The skirting on the frame was cut to match photos, and the detail from the pilot faces were razed. New skid plates were fabricated from styrene, a plow was fitted, cut bars were added and new MU hose holes were drilled. The fuel tank is a Kaslo CNR GP9R tank, which is very similar to the angled tanks that quite a few of the CRP GP7's recieved apon rebuilding. The sideframes were replaced with Athearn Blomberg B sideframes, a speed recorder was added.

The unit went through an abrasive blasting to etch all surfaces for maximum paint adhesion and prepped for painting.

For painting, the unit was primed with Floquil, oversprayed with Scalecoat II white, then Floquil CNW yellow that has been tinted more orange, Model Master Japanese Imperial Green for the body, and floquil engine black for the mechanism.

The decals are Microscale and the entire unit was semiglossed with half Testor's glosscoat and half Testor's dullcoat thinned with lacquer thinner.
