For weighing wagon loads, there are various weighing points where the wagon, including its load, can be weighed. These weighing points need to be regularly calibrated. Calibration is performed using so-called calibration wagons. These wagons have a fixed calibrated weight. Additional weights can optionally be added to the wagon to allow the weight to be adjusted over a wide range.
The calibration wagons do not have brakes because wear on the brake pads could affect the weight of the wagons. The calibration wagons are typically accompanied by a tool wagon in which the extra calibration weights are transported. The wagons were built at the Uerdingen wagon factory starting in 1949.
