In Japan speed tests in 300km/h region have been carried out since Oyama Test Line recorded a 319km/h run in 1979. Meanwhile TGV recorded a 515.3km/h run by an electric locomotive installed with a pantograph in 1990 and ICE did 406.9km/h using similar train in 1988. High speed current collection tests over 400km/h using electric railcars have been desired in Japan. Problems of high speed tests are: train speed approaching wave propagation velocity, multi-pantographs resonance, and too large uplift of contact wires caused by lift. It is necessary to keep wave propagation velocity of contact wire higher than train speed. CS contact wire and TA contact wire were compared in high speed tests because it was impossible to get a good current collecting performance by using hard-drawn copper contact wires. In December, 1993 using these contact wires we carried out high speed running tests of 400km/h region on Jyoetsu Shinkansen with the test train STAR 21 which JR EAST built for high speed tests. This paper gives the current collecting performance of these contact wires predicted by simulation and running tests at 425km/h.

For Projected Shinkansen, 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.
