If a failure of components of a transport-system sliding contact can be predicted, preventive maintenance that is sometimes unnecessary is eliminated and an alternative run-to-failure approach associated with downtime can be avoided. A system and a method detect wear of a transport system, which system has a sliding contact with a current collector and a current-carrying conductor. A current-collector vibration sensor mounted on the current collector is configured to register vibrations produced by driving motion of the vehicle along the current-carrying conductor and to wirelessly transmit the vibrations to a background system. The background system is configured to subject data transmitted to the background system, in particular the registered vibrations, to an analysis and to signal wear of the transport system, in particular wear of the current collector and/or of the current-carrying conductor, on the basis of the analysis.
