A direct current (DC) traction power electric arc suppressing device is provided. The device comprises a parallel resistor-capacitor (RC) circuit electrically connected between a main traction power rail and an associated power rail incline end section with a narrow insulating joint installed between the main traction power rail and the associated power rail end section incline.

A conductor line for supplying an electric load movable on the conductor line in the longitudinal direction of the conductor line, includes at least one conductor strand which runs in the longitudinal direction and has an electrically conductive profiled conductor section for contacting a sliding contact of a current collector of the load and at least one elongated slotted waveguide, which runs in the longitudinal direction, with a longitudinal slot for receiving an antenna which can be moved together with the load. A related current collector and a conductor line system are also provided. The aim is to allow a compact and material-saving design with good fault-tolerant transmission. This is achieved by a conductor line in which the longitudinal slot is tilted by an angle which does not equal 90° about the longitudinal direction with respect to a movement plane on which the current collector can be moved, by a current collector in which the antenna or a part thereof is completely or partly tilted by an angle which also does not equal 90° about the longitudinal direction with respect to the movement plane, and by a conductor line system including such a conductor line and current collector.

A current collector has a sliding contact for making electrical contact with a conductor profile of a conductor line and an antenna for insertion into a longitudinal slot, running in a longitudinal direction of the conductor line. The sliding contact and the antenna can be moved jointly towards the conductor profile in a feed direction by a feed device of the current collector. A conductor line has a conductor profile running in a longitudinal direction, having an elongate cavity and a longitudinal slot adjoining the cavity and running in the longitudinal direction. The conductor profile has at least one sliding contact groove for the sliding contact of the current collector. The antenna is mounted on the current collector so as to be moveable with respect to the sliding contact in the feed direction, and the conductor profile has at least one spacer slide surface running in the longitudinal direction, for a spacer slide of the current collector.

Electric railway systems are disclosed. In an embodiment, the electric railway system includes a continuous conductor, access points, connections, and a microwave link. The continuous conductor runs along the railway track for supplying high-voltage power to trains travelling on the railway system, and supplies high-voltage power to trains travelling on the electric railway systems.
