CNW GP-38-2 4705 in real life was built as a GP-38. In 1991 it was rebuilt to GP-38-2 standards by National Railway Equipment and delivered to the CNW. This model was built from an Atlas GP-38. I stripped and redetailed with such items as a DW plow and new cut bars to better represent CNW 4705. Painting involved using modelflex UP armor yellow and CNW dark green. The underframe was finished with Testors Modelmaster Acryl semigloss black. The decals are Microscale, and the overcoat is half Testor's glosscoat and half Testor's Dullcoat thinned with lacquer thinner.
