Based upon a prototypical structure which was once used to house and repair locomotives, the new structure is a styrene plastic kit molded in appropriate colors, so paint is not required. The sturdy construction features brick detail, opening doors, stalls spaced at 15 degrees, an office which can be positioned in multiple locations, two different styles of ventilators and modular construction. The basic 3-stall kit can be expanded by adding more units to create a bigger facility. Assembles easily using plastic compatible glue. Dimensions: Longest section-10 3/8''; Widest section- 11''; Highest section-3'' Stall size: maximum 8'' locomotive over couplers
