  • Publication number: 20120274759
    Abstract: A method and a device for monitoring a train set include at least one lateral camera and at least two upper cameras. The cameras are fixedly disposed on a track section laterally and above the train set. A region of the contact wire having a carrier device and at least one current collector can be detected by the at least one lateral camera and flanks of the train set can be detected by the at least two upper cameras. An evaluation unit is provided for determining the state of the at least one current collector, at least one clearance dimension of the train set and at least one actual position of the contact wire, or a combination thereof. Detected deviations from standards are indicated and allocated to individual cars.
