Digital transformation has been prioritized in the railway industry to bring automation to
railway operations. Digital Twin (DT) technology has recently gained attention in the railway …

A digital twin is aimed to be a virtual model designed to accurately replicate a physical
system in the digital world. This is why digital twins have become quite popular in recent …

Today, digitalization is a “must” for all industries and sectors. One of the most promising and
popular concepts of digitalization in the last decade is certainly the technology of the digital …

The accuracy of physics-based wheel wear prediction approaches depends not only on the
vehicle-track dynamics model but more importantly on the wear model. The currently …

Locomotive-track interaction is commonly represented by a complex mechanical system
which is modelled in numerical studies. Numerical studies alone are not enough to precisely …

The paper shows the feasibility of building closed-form and fast-to-evaluate surrogate
models via supervised kernel-based machine learning regressions behaving as digital twins …

By modifying friction to the desired level, the application of friction modifiers (FMs) has been
considered as a promising emerging tool in the railway engineering for increasing …

The fatigue life assessment of railway wheels is a critical issue to establish an effective
maintenance strategy. Presently, the traditional nominal stress method is commonly …

To achieve precise prediction of the air pressure changes in the critical components of the
air brake system, including brake pipes (BP), auxiliary reservoirs (AR), and brake cylinders …

Wheel–rail adhesion is a complex tribological problem of wheel–rail rolling contact and is
closely related to the operational safety of high-speed trains. A new design concept of high …
