A 101 TYPE RAIL FASTENING DEVICE (THE NEW TOKAIDO LINE STANDARD TYPE) FOR P.S. CONCRETE SLEEPER

Numerous variations of rail fastening devices have been tentatively fabricated for the new Tokaido line. As the final prototype, the rail fastening device, which was originally developed for 50 kg PS rail, has been modified for application to the new Tokaido line 50 kg T rails. Statical characteristic test and lateral fatigue test were conducted on the tentative product and the results were checked with the anticipated values. The most suitable plastics and compound materials were sought for spring support and the durability of fastening parts was confirmed. The results suggest that a spring clip in the setting area will present no trouble. In this type of fastening, where a hexagonal bolt is screwed into the insert plug embedded in the concrete itself, special care should be taken in designing, so that the bending moment may not directly act on the bolt. There will be no practical trouble with this device, provided the above point is fully attended to.
