The discrete element method (DEM) has been confirmed as an effective numerical method
for modelling railway ballast, and successfully used to analyse a wide range of ballast …

The prediction of wheel/rail rolling contact fatigue (RCF) crack initiation during railway
operations is an important task. Since RCF crack evolution is influenced by many factors, its …

Railway turnouts are a necessary part of railway infrastructure, used throughout the network
to direct trains to the desired path, thus ensuring the smooth running of every train. Their …

To study the law of wheel set lateral displacement (WSLD), a test system is equipped with
lasers for the switch and crossing panel instrumentation. Some measurements including …

Wheel flange climb derailment of vehicles in railway turnouts is a serious safety issue. In
particular, derailment accidents in smaller turnouts, caused by poor track alignment before …

A novel high-strength steel design is proposed, with a fine bainitic microstructure free from
inter-lath carbides, for railway crossings applications. The design is based on the phase …

Railway crossings are subjected to a severe load environment leading to damage and
degradation of rail profiles. The damage is the result of the high magnitudes of contact …

Hollow wear is a common type of wheel profile evolution in high-speed railway, causing
special contact characteristics in turnouts. Taking into account the flexibility of wheelsets and …

Two experimental tools to measure the railway crossing dynamic responses are presented.
One system is ESAH-M equipped with a 3-D accelerometer and a speed detection sensor …

The turnout causes significant vibrations of the wheel-rail system. In this study, based on the
modal superposition method and finite element method, the flexibility of wheelsets and …
