Study on the Transverse Restrainers of the Plate Type Elastometric Pad Bearings in Existing Railway

In this paper, the factors which cause the enhancement of the bridge amplitude in existing railway are analyzed. Based on the results, the transverse restrainers of the plate type elastometric pad bearings is developed, the materials and construction technology of it are introduced. The safety of existing railway in the high speed condition can be controlled by using the transverse restrainers. This provides a reference for the reconstruction of existing railway.
