The invention relates to a rail monitoring element (SUE) comprising a carrier (T) on which a strain sensor, in particular comprising an optical fibre (F) having a fibre Bragg grating (FBG), is attached. According to the invention, the carrier (T) has an adhesive layer (K) for adhesive attachment to a rail (S) having a thermally activatable or thermally curable adhesive, the adhesive layer (K) comprising a heating element (HE) having contacts (KO) that can be supplied with electrical energy. The rail monitoring element according to the invention can be installed more easily and in a manner which saves more energy.
