The turnout is the key equipment for guiding trains to change lines in railway track, which can affect the vehicle running smoothness and limit the train speed drastically. This paper proposes an o...

A vehicle-track-substructure dynamic system model is developed using FE tool Abaqus coupled to an MBS code Gensys. A vehicle dynamics is simulated in Gensys and the contact force and contact patch from the MBS simulation are used as input file in a d

Monitoring the condition of switch and crossings is a challenge for infrastructure managers (IMs). It requires specially trained switch inspectors to manually check the condition of the track. Hence, a fast and cheap system to continuously monitor th

Rail corrugation, a quasi-sinusoidal irregularity of the rail head, is a common issue experienced throughout the railway networks worldwide. It generally leads to high wheel-rail dynamic loads, increased noise emission, and poor ride comfort. Most co

Expensive and time-consuming maintenance operations are routinely performed to preserve the ballast mechanical properties in railway lines. Binding agents are used for ballast stabilisation. Four different additives based on bitumen, organosilane, li

A methodology for the simulation of degradation of rail profiles in switches & crossings (S&C) is presented. The methodology includes: simulation of dynamic vehicle-track interaction considering stochastic variations in input data (such as wheel prof
