Abstract
A rail-monitoring element includes a carrier on which a strain sensor is attached. The strain sensor may be an optical fiber having a fiber Bragg grating. The carrier has an adhesive layer for adhesive attachment to a rail having a thermally activatable or thermally curable adhesive. The adhesive layer has a heating element having contacts for receiving electrical energy. The rail-monitoring element can be installed more easily and in a manner which saves more energy.
