It becomes more important to reduce the noise generated from Shinkansen train for further speed-up of Shinkansen. We developed the high-speed test train "FASTECH360" that has new equipment such as low-noise pantographs, "multi-segment slider", pantograph noise insulation plates and sound-absorbing panels for the noise from the lower area of car bodies. We investigated the noise distribution of "FASTECH360" by using a spiral microphone array, and we have taken countermeasures for the noise sources of "FASTECH360" based on the primary results of high-speed tests. Currently, the results show that the noise level of "FASTECH360" at the speed of 330km/h is approximately equal to that of the present commercial train at the speed of 275km/h (at a distance of 25m from the track).

Since the establishment of the Shinkansen Speed-up Project in 2002, JR East has been developing various technologies seeking for world top level Shinkansen not only in operating speed but also in safety, environmental friendliness and riding quality. In this project, JR East has developed two high speed experimental train sets, Fastech360S and Fastech360Z. The technological target of Fastech360 is to realize 360km/h commercial operation. After a 2-year test running of them, JR East decided to increase the maximum operation speed of Tohoku Shinkansen from 275km/h to 320km/h. This paper describes the overview of the R&D project and the developed technologies, and the subjects to be solved for further speedup for the future as well.
