HO Scale brass diesel locomotive set from Railway Classics, featuring the Chicago Burlington & Quincy Denver Zephyr EA units "Silver King" #9906A and "Silver Queen" #9906B. These represent the iconic EMD EA "shovel nose" diesel locomotives that powered the famous Denver Zephyr streamlined passenger train.

The Denver Zephyr was one of the Burlington Route's premier named trains, operating between Chicago and Denver from 1936. The distinctive "shovel nose" EA units were among the most recognizable diesel locomotives ever built, with their sleek streamlined carbody design that epitomized the Art Deco styling of the streamliner era.

Railway Classics was known for producing detailed brass models with authentic features. This A&B set includes both powered A-unit "Silver King" with operating headlight and marker lights, and powered B-unit "Silver Queen" with operating back-up light. Both units feature factory painting, interior details, knuckle couplers, and original spare parts.
