The Nice Atlas Undecorated RS-3 Loco HO is a vintage diesel locomotive model designed for model railroads and trains enthusiasts. This unassembled kit features a gray color and a Bo-Bo wheel configuration, made of plastic material in a 1:87 scale. With an analog control system and light function, this locomotive measures 9 inches in length, 2 inches in height, and 1.4 inches in width, weighing 1 pound. Made by Atlas/KATO in the United States, this locomotive is part of the transportation theme and is compatible with a two-rail system. It is suitable for ages 8-11 years and is a great addition to any model railroad collection. This engine was preowned, but is in new condition, appears unused, and is a kit requiring modest assembly. Ready to be painted and decaled. .
