Keep trains moving safely across your line with this big interlocking control tower. The HO Scale model is based on a Norfolk & Western prototype at Forest, Virginia, near Roanoke. The kit features peel and stick windows for the upper story which are laser-cut to speed construction. The elaborate exterior staircase, also made of laser-cut wood, is also included. The roof is detailed with "tin" sheets, plus a cast metal smokejack. Perfect for any busy yard or interlocking in the steam- or diesel-era. Measures 5 x 2-1/2 x 4-1/4" (12.5 x 6.2 x 10.6 cm).
