Development of Tie Plate for Rigid Crossings with Elastic Support

Abstract

In rigid crossings of turnouts laid on composite sleepers with direct fixation of the Shinkansen trains has large dents on nose rails compared to those of ballasted turnouts. The authors focused on the difference in the dynamic load depending on the support condition, and to make depth of dents on nose rails in composite sleepers on direct fixation turnout equal to that for a ballast turnout, developed tie plate for rigid crossings with elastic support. With the conventional tie plate, it is compatible and replaceable.
