Railway Superstructure for High-speed Rails

Popis výsledku v původním jazyce

The construction of the track is solved as a conventional (with track ballast) or as aballastless track (without track ballast). When deciding on the choice of the most suitable track designfor high-speed rail, it is necessary to emphasize that with increasing line speed, the requirements forthe quality of the track geometry increase, including the size of the deviations of individual geometricparameters of the track from the projected values. When assessing the choice of track structure –especially for high-speed rails – it is therefore necessary and correct to assess the total costs (investmentand operational) for a sufficiently long time. DB Netz AG’s present experience with a ballastless tracksince its first implementation in 1972 in Rheda station, for almost 50 years, shows that the requiredlifetime of 60 years has its real justification. In addition, current research and development in the fieldof ballastless track is moving towards extending the life of ballastless track well beyond this limit. Thepaper is focused on the comparison a ballasted and ballastless track construction. It deals in moredetail with evaluation of the advantages and disadvantages of a ballastless track construction. Themain objective is to assess the use of ballastless track structure for the construction of high-speed lines.
