Model of 4 railroad crossing gates with warning lights and an electronic gong in N scale (1:160). The length of the gate is meant for a single lane of traffic. Set comes as seen in the picture (fully assembled, unpainted). The crossing gates pivot on an axle and can be either up or down. The warning lights are static and do not function, the size of the model does not allow this. The unit should be placed on the curb about 1 mm above the crown of the roadway.
