Type Gr 20 Kassel: The riveted freight wagon of the class district Kassel is based on the first class wagon according to sample sheet A2. In order to use the car frame of the Om, the car body has been adapted and is therefore shorter than provided in the sample sheet A2. Special features of the Gr are u.a. the tonneau roof, the brakeman's cab mounted on the undercarriage as well as a loading and a ventilation flap on each side wall. Diagonal braces to stiffen the side panels next to the doors give the car extra stability. New to these models: The wheelsets are matt nickel plated in these cars - so they look even more natural. In addition, we have optimized the clutch: two small magnets support the center position of the clutch and provide improved guidance in the scenery.
