On rail tracks equipped with strain gauges, sensor elements are attached directly to the rails by bonding or welding and are then connected electrically, which may be carried out either at site or as part of the prefabrication of rails at the factory. Both methods involve considerable work on the track, which disrupts and is disrupted by rail traffic. The aforementioned problems also arise in the course of tracklaying and track maintenance work, The invention solves this problem by mounting prefabricated sensor beams on the rails using bolts and nuts.
