A rail structure arrangement for a system ("S") for propelling an electrically propellable vehicle, by one or several batteries or a set of batteries, along a roadway, the system comprising: "a" a plurality of roadway sections subdividing the roadway, wherein each one of the roadway sections (2al, 2a) comprises two or more elongated tracks or slits (51, 52) having conductors (4a, 4b) introduced therein adapted to be supplied with current and put under voltage and having contact surfaces (4a', 4b'), wherein the conductors (4a, 4b) are connectable via a switch to one or more vehicle-external power sources ("III"), for thereby enabling charging of said set of batteries ("II", B) belonging to the vehicle, but primarily driving the vehicle along the roadway and the roadway sections (2al, 2a), and "b" one or more vehicles propellable by means of an electric motor or motors, with each of the respective vehicles comprising a control circuit (100, "R1") adapted for distribution of power, and adapted for creating required power and/or speed control, wherein said vehicle is provided on its underneath side with arm-shaped contact means displaceable up and down and sideways, in relation to the direction of transportation of the vehicle, wherein said elongated track and the conductors (4a, 4b) extend along the roadway and the roadway sections (2al, 2a) and wherein said contact means is coordinated with a control equipment of the vehicle for creating an adaptation of the contact means so as to at least offer a mechanical and electrical contact with said conductors (4a, 4b) and the contact surfaces (4a, 4b) thereof, characterized in that said rail structure arrangement comprises at least three tracks (51, 51a, 52) disposed parallel to each other in a common rail structure, with at least two of these tracks (51, 52) supporting and containing individual electric conductors (4a, 4b) with contact surfaces (4a', 4b'), adapted to be put under voltage, and wherein at least one additional track of said at least three tracks is disposed adjacent to a track containing one of said conductors (4a, 4b) with said contact surfaces (4a', 4b'), said additional track having an upper edge portion adapted to face the highest point of the roadway, said upper edge portion being disposed at a higher level than an upper edge portion of said track containing one of said conductors. "a" a plurality of roadway sections subdividing the roadway, wherein each one of the roadway sections (2al, 2a) comprises two or more elongated tracks or slits (51, 52) having conductors (4a, 4b) introduced therein adapted to be supplied with current and put under voltage and having contact surfaces (4a', 4b'), wherein the conductors (4a, 4b) are connectable via a switch to one or more vehicle-external power sources ("III"), for thereby enabling charging of said set of batteries ("II", B) belonging to the vehicle, but primarily driving the vehicle along the roadway and the roadway sections (2al, 2a), and "b" one or more vehicles propellable by means of an electric motor or motors, with each of the respective vehicles comprising a control circuit (100, "R1") adapted for distribution of power, and adapted for creating required power and/or speed control, wherein said vehicle is provided on its underneath side with arm-shaped contact means displaceable up and down and sideways, in relation to the direction of transportation of the vehicle,
