The actual trend of railway industry on track surveying is heading up the development of fast
automated methods for continuous monitoring of track quality. This paper presents a model …

Railway track geometry varies along routes depending on topographical, operational and
safety constraints. Tracks are prone to degrade over time due to various factors, with …

While the track irregularity in turnout areas has a significant impact on wheel-rail contact,
driving safety, and stability, the impact of track irregularity in front of the incoming turnout on …

Track irregularities induce potential risks to the safety and stability of railway track systems.
This paper proposes a novel methodology to identify vertical and lateral track irregularities …

Dynamic load histories of vulnerable fatigue sites in structures are of paramount importance
for safety design, and such load–time histories with long duration are usually lumped …

This paper describes a novel method for the estimation of the trajectory and orientation of a
rigid body moving along a railway track. Compared to other recent developments in the …

Condition monitoring of railway track geometry using instrumented in-service vehicles has
been the subject of extensive research aimed at replacing or enhancing the data provided …

Temperature gradient is an important factor affecting the periodic rail deformation of CRTS
Ⅲ and the running stability of high-speed trains. The Comprehensive Empirical Mode …

In this study, an evenness improvement method for new high-speed turnout crossing areas
is proposed for the development of high-speed turnout and amplification of the wheel–rail …

Purpose This article aims to predict the rapid track geometry change in the short term with a
higher detection frequency, and realize the monitoring and maintenance of the railway state …
