This car set consists of two DR type Rf4 roller cars as was used on many narrow gauge lines in Saxony. The paint scheme and lettering are prototypical for Era III. The center part of the car floor is constructed of die-cast metal so that the car has sufficient weight to run well on track when the car is not loaded. The chock block restraints can be swung and are adjustable. Even standard LGB cars with a gauge of 45 mm / 1-3/4" can be loaded on this car by means of the restraint blocks included with this car set. The roller cars are prototypically coupled to each other and to a locomotive or another car with a standard LGB coupler by means of the coupler drawbars included with this set. The cars have metal wheel sets. Length of a car 34 cm / 13-3/8".
