Quality of Slab Track Construction – Track Alignment Design and Track Geometry

Investigation of the Influences of Track Superstructure Parameters on Ballasted Railway Track Design

The main design criteria of ballasted railway tracks include rail deflections, rail bending stresses, rail wheel contact stresses, sleeper bending moments and ballast sleeper contact pressures. Numerous criteria have been defined for the design of ballasted railway tracks owing to the various mechanical properties of track components and their complex interaction. Therefore, railway track desig...

Remarks on Modern Track Geometry Maintenance

A short survey on modern track maintenance methods is given, concentrating on the developments in recent years. The ongoing refinement of the machinery should be shown as the influence of IT-solutions. On top the economic view to the track infrastructure is briefly demonstrated. Further developments in track hardware solutions must respect the obtained high level of track work mechanization. H...

Slab Track Design for High-speed

If the low-maintenance characteristics of slab track on open line are to be retained, great care must be taken to ensure that the subgrade layers are homogenous and capable of bearing the loads imposed [2]. The slabs can be precast or poured on site. The most known tracks with precast slabs are Shinkansen line in Japan and Max Bögl slab track designed in Germany [2], while as examples of the tr...

Influences of Railway Track Geometry Parameters on Ground-Borne Vibration

One of the most important challenges in the development of urban railways network is the effects of railway vibrations on human and adjacent structures. Although various investigations into the sources of railway vibrations have been conducted, very few research works have been reported on the influences of track geometry parameters on the level of vibrations. This is addressed in this resea...
