Abstract
A damping element for a rail vehicle including a first section for fastening to a rail vehicle and a second section for introducing a force acting horizontally upon the rail vehicle. A monitoring system for the dampening element including a sensor attached to the dampening element for sensing a change in a distance between the first section and the second section, a data memory, a processing unit designed to determine information regarding the change in the distance and to store said information in the data memory and a local energy supply device for the autonomous supply of the processing unit.
