There is a growing need to implement modern technologies, such as digital twinning, to
improve the efficiency of transport fleet maintenance processes and maintain company …

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 shakedown map is one of the key prediction models used in railway engineering to
evaluate rolling contact fatigue (RCF) damages of wheels and rails. The objective of this …

The information that automated train control (ATO) systems use to improve safety and
reduce power usage is limited by on-board and wayside monitoring applications and …

The dynamic process of the railway track–rolling stock interaction is characterized by time-
dependent dynamics that are determined by both the varying characteristics of the …

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 …

Abstract Evaluation and prediction of wheel-rail rolling contact fatigue (RCF) damage can
provide important theoretical guarantees for the service safety of wheels and rails and help …

Abstract Wear and Rolling Contact Fatigue (RCF) on wheels and rails are influenced by
relative motions between the studied rail and wheel pair, and therefore influenced by train …
