Four-axle type KB coach with open crossovers and without a toilet. Many passenger cars were rebuilt to improve travel comfort on the Harzquer and Selketal Railroads. In the process the cars were given new car bodies. The model reproduces such a car in Era VI in the new prototypical dark red HSB paint scheme with finely executed lettering. The car has a new, previously unused car number. The model has metal solid wheels.
