HO Scale brass diesel locomotive from Challenger Imports, manufactured in Korea by Samhongsa. Features Chicago Burlington & Quincy EMD E7A unit in factory-painted and plated finish. Challenger Imports was renowned for producing high-quality brass models with exceptional detail and magnificent factory paint jobs, considered "collector grade" by enthusiasts.

The EMD E7A was one of the most successful passenger diesel locomotives ever built, and the Burlington Route operated these units extensively on their premier passenger trains including the California Zephyr, Denver Zephyr, and other famous Zephyr fleet services. These powerful units were essential to the CB&Q's streamlined passenger operations during the golden age of American passenger railroading.

This model features the ultra-smooth and quiet motors and gearboxes that Samhongsa was known for, along with incredible level of detail including fine-scale features that made Challenger Imports models highly sought after. The combination of factory painting and plating represents the authentic Burlington Route passenger diesel scheme with premium finish quality.
