Abstract

An arrangement adapted for letting water pass by electrical conductors and their contact surfaces related to a track of a system adapted for electrically driving a vehicle along a roadway. The vehicle is provided with a current collector which is displaceable up and down and sideways in relation to the direction of transportation, in order to be brought into mechanical and electrical contact with elongated tracks positioned below the roadway and comprising a conductor adapted to be supplied with current and put under voltage. At least two or three tracks are disposed parallel to each other in a common rail structure, with at least two of these tracks being adapted to support and contain individual electrical conductors with contact surfaces put under voltage, and wherein at least one track is disposed closer to the highest point of the roadway and adjacent to a track containing one of said conductors with contact surfaces, which may be put under voltage.
