Abstract: The present invention relates to a weighing module for measuring wheel contact forces of rail-bound vehicles, comprising a measuring rail and a number of strain gauges, wherein the strain gauges are applied directly on the measuring rail. The measuring rail comprises a load introduction region, made of at least one load introduction part, and at least two deformation bodies, which are connected fixedly in each case to a load output plate and, via a hinge, to the load introduction region. The strain gauges are arranged on the deformation bodies and capture the shear strain acting between the hinges and load output plates.
