PERFORMANCE EVALUATION OF AN ADVANCED DESIGN TURNOUT WITH SPIRAL GEOMETRY, HOLLOW SWITCH TIES AND WELDED HEEL FROG

Railroad track turnouts are key junction points in keeping rail traffic flowing. As such, they determine the performance of a railroad, while also serving as a major maintenance cost. This article looks at how enhanced features on new turnouts can help reduce maintenance and boost performance. Evaluations of different turnout designs focusing on reducing maximum lateral forces with optimal geometry are presented. The article describes advanced designs with spiral geometry, hollow switch ties, and frogs with welded heel rails. Performance evaluations look at: surface maintenance, failed or broken components, switch throw, dynamic loads, ride quality, as well as areas for improvement.
