1. A regenerative energy absorption device for damping forces which occur during operation of a track-guided vehicle, wherein the energy absorption device comprises:
at least one spring device with an elastomer body which at least partially deforms elastically when forces are introduced into the energy absorption device, wherein the elastomer body is at least partially formed from an electrically conductive material, wherein an electrical resistance of the electrically conductive material varies under tensile and/or compressive load, and wherein the energy absorption device includes a resistance sensor device for detecting an electrical conductivity or an electrical resistance of the electrically conductive material.
