Tests experiences in small radius curves of continuously welded rail tracks

Abstract

The continuously welded rail tracks are very popular and wide because of their advantages. Although the continuously welded rail tracks have special mechanical properties and requirements and they need special construction and maintenance. One of the most important requirements of the continuously welded rail tracks is the big lateral resistance. The lateral resistance can be increased by several solutions, which are highlighted in the following three methods: ballast bonding technology and safety caps and Y steel sleepers. The main goal of this publication is to demonstrate the tests and measurements made in three different track sections, to compare and analyze the results of the measurements and to summarize the conclusions. © Periodica Polytechnica 2011.
