For projected Shinkanse, it is necessary to develop an economical overhead catenary system
allowing stable train operation at high-speed and meeting the transport demands. In order to
develop a new overhead catenary system for this purpose, we designed a high tension simple
catenary system with CS contact wire (Copper contact wire with Steel-core), and constructed
this system on Tohoku Shinkansen line for operation test. During 4 years, we measured contact
loss of pantograph, uplift and stress of contact wire, its maintainability including the wear
of contact wire, and others. The test results so far obtained prove that its performance is
as high as that of high-tension heavy compound catenary system.
