Turnouts fixed directly to composite sleepers for the shinkansen have large dents on the nose rails, compared to those of ballasted turnouts. To solve this issue, focusing on the dynamic load difference under different support conditions, the authors developed the new baseplate for rigid crossings with elastic support. The developed baseplate can make the depth of dents on nose rails of turnout fixed directly to composite sleepers equal to that of a ballasted turnout. In addition, it is compatible and replaceable with conventional baseplates.
Shimizu et al. (Fri,) studied this question.
