Abstract: This support (36), as a profile in an electrically insulating material, comprises a substantially planar upper surface (50), provided with a longitudinal flute (60) intended for receiving a track segment, and a longitudinal groove (70) intended for receiving a low voltage electric power supply cable; and a lower surface (52) intended to bear upon a base for maintaining the support in the roadway. It is characterized in that the lower surface (52) is curved, preferably V-shaped, so that the support is concave so as to be at least transversely maintained in a recess with a mating shape, made in the base.

Abstract: A system for supplying current through the ground for an electric vehicle, especially for an electric rail vehicle, includes a succession of conducting segments (16A, 16B, 16C, 16D) which are electrically isolated from each other and together form a conducting supply track against which at least one supply collector shoe (32) on the vehicle is applied, and a set of high-voltage supply devices (20) each connected to a conducting segment and each provided with a detector capable of detecting a collector shoe and with switching devices (45) suitable for selectively causing a corresponding segment to be supplied with current when a collector shoe is present on the segment and causing the said collector shoe to be connected to a zero-potential source (26) when a collector shoe is not present thereon.

Abstract: An electric current collection system comprises a continuously live conductor, a shield enclosing the continuously live conductor, and contact segments extending through the shield in a row extending along the length of the continuously live conductor and resiliently mounted so as normally to be electrically isolated from the continuously live conductor and from each other but adapted to co-operate with a current collecting device running along the row to make electrical contact with an external contact surface of each segment in succession and displace the segment to bring an internal contact surface afforded by it into electrical connection with an internal contact surface afforded by the continuous live conductor. Each segment includes a bar portion affording an internal contact surface and extending through the shield in a direction substantially perpendicular to the length of the live conductor and to the direction of displacement of the segment.
