Summary
In this paper detailed research results for Polish railway lines are given. The paper includes the technology methods, mechanical, electrical, exploitation properties of CuAg0,10 trolley wires (including wear tests under different friction speeds, load forces, current intensities and types of current collector), catenary ropes, CuNi2Si traction equipment and laboratory research (i.e. relaxation of holding forces, disconnecting force researches). The results of comparative research on dropper clamps from different manufacturers are presented. Research results for the overhead line load-carrying capacity with the results of static analyses of overhead lines and pantograph strips with the dynamic cooperation between these elements are given. Additionally research results for the design of a new kind of railway traction support construction are shown in this paper. The influence of all traction elements over the single railway poles and portal constructions are shown.
