A rail contact element for drop off detection is disclosed, wherein the rail contact element is mountable to a rail and includes a spring element, a main body which holds the spring element and an optical fiber. The spring element is in a tension state or in a relax state depending on a mounting state of the rail contact element. The optical fiber includes an outlet surface for emitting a light beam and the rail contact element further includes a reflector element. The spring element, the reflector element and the optical fiber are arranged so that the influence of the reflector element on the light beam is different in the tension state than in the relax state.
