The present invention provides an improved catenary wire system for an overhead line equipment (OLE) installation. Known OLE installations are prone to sagging and hence require a large number of support structures, which are expensive to install and maintain. These structures also appear “cluttered” and ungainly. The catenary wire system of the present invention comprises a fibre reinforced composite catenary wire configured to suspend a contact wire; and at least one elongate electrically conductive element arranged generally parallel with the catenary wire. It has been found that the catenary wire system of the present invention is able to withstand increased tensions when compared to known OLE installations, which reduces the amount of catenary wire sag, and can thereby reduce the number of support structures required by an OLE installation.

Disclosed is a motorized transport system comprising: a transport line comprising: a first cable; a second cable, wherein the first and second cable are made of a second conductor; and, an insulation layer, wherein the insulation layer is made of an insulator; wherein the insulation layer bonds the first cable to the second cable, insulates the first cable from the second cable, and, does not allow the first cable to contact the second cable; a plurality of line anchors fastened to the transport line; a power means for supplying an electric current to the first and second cable; and, a chassis comprising: a housing; a first motor; at least one first cable pulley; at least one second cable pulley; a junction box; a first internal power supply link; a first cable pulley-junction box link; a junction box-second cable pulley link.
