Abstract: Disclosed is a lock-on device including a member and a grounding pad. A first end of the member is configured to be connected to a guide frame of a rail vehicle. The grounding pad is attached to a second end of the member. The grounding pad may be attached to the member in any location suitable for collecting ground from the guide beam during use. A pair of lock-on devices is installed on the vehicle, such that one is located on each side of the guide beam. Since the lock-on device is attached to the guide frame of the vehicle and engages the underneath of the guide beam, any force tending to tip the vehicle will cause the lock-on device to “grab” the guide beam. The relationship of the guide beam and the grounding pad prevents the vehicle from tipping. Thus, track jumping and roll over are inhibited.

Abstract: The invention relates to a method for forming output signals of an interference current monitor or of a state monitor of an electrical rail vehicle with current being drawn from a power grid, and optionally a current also being delivered back into said power grid, via a current collector. In the case of a state monitor, not only interference currents but also further fault states are identified and signaled. The method steps include detection by measurement and digitization of the vehicle current flowing via the current collector or of other measurement quantities which make it possible to infer vehicle states which leads to interference currents, and digital processing of these measured values with determination of the spectral density of interference currents or of interference values of the other measurement quantities, a multistage system of response thresholds being used in order to evaluate the spectral density.

Abstract: A container for a rail vehicle for the installation of electric and electronic equipment is proposed. The container (1) is formed from an extruded section (2, 3) bent in the edge regions (10) and provided with lid (22) and rear panel (21). The extruded section used for forming the wall has a special structure adopted exactly to the requirements of the container (1) and having at least one coolant duct (13) of closed cross section. A cooling circuit within the equipment is formed by means of the cooling ducts, in which case the coolant may be pressurized. The thermal energy produced and radiated in components installed individually in the interior space of the container (1) is absorbed by the cooling circuit within the equipment and is dissipated via the surface of the container to the outside atmosphere.
