A transportation system with a non-rail-bound, electrically or diesel-electrically driven vehicle, has a two-pole overhead conductor system with contact wires forming supply and return conductors. The vehicle has a current collector for the supply of electrical energy through sliding contact with the contact wires. A video detector on the vehicle determines a position of the contact wires relative to the vehicle. Marking elements mark the position of the contact wires. The video detector is oriented for taking video images of the marking elements, and an evaluation unit recognizes from a recorded video image whether contact wires are present above the vehicle and, when they are present, determines their position relative to the vehicle. Through the improved recognition of the position of the vehicle relative to the overhead conductor the operational safety of the transportation system is improved.

An overhead line system provides electrical energy for an electrically driven vehicle by use of an overhead line. The overhead line system has a plurality of catenary systems which each have a contact wire connected to a carrying cable by a plurality of connecting devices and which are arranged, on the basis of parallel zones, to form a continuously accessible overhead line. The overhead line system further has an overhead line which is arranged in a curvature section in such a way that the vertical projection of the overhead line has a curved profile in a horizontal plane. The overhead line system also has a curved parallel zone which is arranged in the curvature section in such a way that the vertical projection of the parallel zone into the horizontal plane follows the curved profile of the projection of the at least one overhead line in the curvature section.
