The invention concerns a rail contact element (10, 10a, 10b, 10c, 10d, 10e, 10f, 10g) for drop off detection, wherein the rail contact element (10, 10a, 10b, 10c, 10d, 10e, 10f, 10g) is mountable to a rail (12) and comprises a spring element (14), a main body (16) which holds the spring element and an optical fibre (18), wherein the spring element (14) is in a tension state or in a relax state depending on a mounting state of the rail contact element.The optical fibre (18) comprises an outlet surface (20) for emitting a light beam (22) and the rail contact element (10, 10a, 10b, 10c, 10d, 10e, 10f, 10g) further comprises a reflector element (24). The spring element (14), the reflector element (24) and the optical fibre (18) are arranged so that the influence of the reflector element (24) on the light beam (22) is different in the tension state than in the relax state.
