Standards for rail, track structures and track materials used for the 398-km extension of the New Sanyo Line to Hakata are described. Though not basically different from those used for the earlier high-speed lines, standards and structures take into account future operation at even higher speeds. Improvements also take into account 10 years of experience with maintenance of the older Shin Kansen. Concrete slab track, chosen for low maintenance requirements, is employed as the standard for about 70 per cent of the line. Slab track is seen as essential for future high speed lines, although measures will have to be taken to attenuate noise and vibration from such a track structure.
