This research is focused on energy harvesting from track vibration in order to provide power
for the wireless sensors which monitor railroad health. Considering that track vibration has …

The presence of rail surface damage leads to increased vibrations on railway bridges as
wheels cross the localized irregularities. These short wavelength irregularities appear …

A series of cyclic loading tests were performed to establish the effect of particle breakage on
the damping, resiliency and serviceability of railroad ballast. Five geogrids of triangular …

Transition zones such as level crossing and bridge approaches are critical links in railway
networks due to higher degradation rates and maintenance needs. In this context …

In this paper, a two-dimensional numerical model is developed to investigate the effect of rail
pad stiffness on the wheel/rail force in a slab track with harmonic irregularity. The model …

Abstract Effects of sand contamination of railways on the loading pattern of pre-stressed
concrete sleepers were investigated, using a FE model of railway track developed and …

Abrupt track vertical stiffness variations along railway tracks can lead to increased dynamic
loads, asymmetric deformations, damaged track components, and consequently, increased …

Railway transition zones (RTZs) are regions where abrupt track stiffness changes occur that
may lead to dynamic amplifications and subsequent track deterioration. The design …

Railway track transition zone is a zone where track stiffness changes abruptly. This change
occurs where the slab track connects to a conventional ballasted track, at the abutments of …

Nowadays, the rail fastening systems play an important role for preserving the connection
between the rails and sleepers in various conditions. In this paper, stress based concept is …
