There is a spare wheel on the flatbed. The model of the Culemeyer design road roller is a 4-axle version. Length including drawbar approximately 11.5 cm / 4-1/2".
Culemeyer Design Road Roller Only a few discoveries are allowed to bear the name of the discoverer. Yet the almost revolutionary discovery of the road roller by the German State Railroad director Dr. Eng. Johann Culemeyer in the early Thirties is one of these exceptions. In order to stand up to the competition from trucks, he designed a road vehicle suitable for transporting freight cars. Thus, starting at the end of 1933 these cars could be transported by road with no problem to industrial operations without a rail connection. This "Traveling Connecting Track" with 16 to 24 wheels was built by the car builder Gotha and the firm Kaelble in Backnang developed suitable heavy-duty tractor units for it.
