In use from the early 1900s until computers took over in the 1980s, a few are still standing. A great starting point for a trackside scene, this model is complete with an exterior stairway, as well as simulated rods for the control system. It has the look and feel of structures used along railroads large and small. Several can be used along your line to capture the "family" look so common to railroad architecture. Plastic parts are molded in color and detailed to simulate wood construction. Decal signs and complete instructions are also included. .
