THEORETICAL STUDY OF MECHANICAL PROPERTIES OF ELEVATED OPEN- FLOORED DIRECT-FASTENED TRACKS

Direct attachment of rails to elevated open-floored structures to assure they will be self-clearing in snowstorms produces a track structure different mechanically from either conventional ballasted track or concrete slab track. Normally there is little deformation, but should the structure deflect, the resulting track deflection is difficult to correct. Japanese National Railways has tested such construction on the Kansai line at speeds to 100 km/h, and is considering it for extensions of the Shin Kansen network. With use of a rubber mat, this elastic track structure is rated capable of operations to 260 km/h for the high-speed trains.
