Long-term geometry evaluation in switches and crossings and their mutual comparison

Popis výsledku v původním jazyce

The influence of the switch and crossing structure type on the track settlement has been investigated. The settlement of the track is one of the most important parameters that influences the track quality and the dynamic behaviour of the track by passing the trains. The switches and crossings with various innovative structure elements installed into the network of the Czech Railway Infrastructure Manager since 2010 have been measured using levelling of rail head at regular intervals, and the settlement of individual areas of the turnouts was evaluated. Conventional turnouts, turnouts with elastic fastening systems, turnouts with under sleeper pads (USP), fixed crossings, and crossings with movable parts and turnouts designed for high-speed lines have been measured and evaluated. Each turnout area was divided into five specific areas, which were further monitored and compared with each other. The monitored parts were the area in front of the turnout, the switch panel, the closure panel, the crossing panel and the area behind the turnout. This paper focuses on the crossing panel, which is the most dynamically loaded region. The main goal of the research was to evaluate all measured data over time and compare the settlement rates of the individual turnout structural types with each other while maintaining the same method and equipment for the measurements. Through a long-term comparison, the benefits of individual innovative structural elements have been gained, and the degree of this benefit has been established for each turnout.
