Atlas' new HO scale Three Stall Brick Roundhouse is based on a prototype once used to house and repair locomotives. This styrene plastic kit is molded in appropriate colors, so paint is not required. You can easily assemble it using plastic compatible glue. Construction features include brick detail, opening doors, stalls spaced at 15 degrees, an office that can be placed in various locations and two different styles of ventilators and modular construction. Locomotives up to 12 inches in length can be held in the three stalls. The modular construction can be expanded with additional stalls. This roundhouse is compatible with Atlas' HO turntable, #305, sold separately. Dimensions: 14 3/8 inches x 15 inches x 4 5/8 inches.
