NOVELTY - System for retrofitting energy supply modules in the region of a transport route comprising transport route extending along both longitudinal sides of many support poles (1), comprises many transverse support ropes (11), many solar panels (21), at least one elongated attachment element (10), at least a first deflecting element (12), and at least one fastening element. The transverse support ropes are extendable transversely to the transport route between oppositely lying support poles on the transport route. The solar panels are mounted on the transverse support ropes.    USE - The system is useful for retrofitting energy supply modules in the region of a transport route.    ADVANTAGE - The system retrofits a railway route with energy modules without interrupting the rail transport for prolonged periods.    DETAILED DESCRIPTION - System for retrofitting energy supply modules in the region of a transport route comprising transport route extending along both longitudinal sides of many support poles (1), comprises many transverse support ropes (11), many solar panels (21), at least one elongated attachment element (10), at least a first deflecting element (12), and at least one fastening element. The transverse support ropes are extendable transversely to the transport route between oppositely lying support poles on the transport route. The solar panels are mounted on the transverse support ropes through the transport route. Each support pole is made of many support poles. The elongated attachment element is attachable to each support pole, and enhances the rigidity of each support pole over a large part of the length of each support pole. The first deflecting element is attachable to an upper portion of the support pole. The first deflecting element routes the transverse support ropes from its transverse orientation into a vertical orientation. The fastening element is attachable at a lower portion of the support poles. The fastening element anchors the vertically oriented support rope to the lower portion in a stretched manner. The force, which is applied from the solar panel to the transverse support rope, is passed through the transverse support rope over the first deflecting element and into the lower portion of the support poles.    DESCRIPTION OF DRAWING(S) - The figure 4 shows schematic cross-sectional view of the support pole equipped with adjustable solar panel.
