Railway track maintenance and renewal are vital for railway safety, train punctuality, and
travel comfort. Therefore, having cost-effective maintenance is critical in managing railway …

In the past 20 years, many studies have been performed on ballast layer inspection and
condition evaluation with ground penetrating radar (GPR). GPR is a non-destructive means …

The increase of train speed and axle load is an essential goal to make the railway transport
more and more competitive for passengers and freights. On this basis, the unevenness of …

Profusive cracking leading to the deterioration of prestressed concrete sleepers has retained
the sleepers from being exploited to their full extent. In addition, excess utilization of cement …

The maintenance strategy in railway transportation is crucial in ensuring safety, availability,
and reducing operating costs. However, finding the optimal maintenance plan that takes into …

This paper compares two imperfect repair models for a degrading system, with deterioration
level modeled by a non homogeneous gamma process. Both models consider …

Real-time evaluation of the mechanical qualities of ballast beds is essential for improving
tamping effort in railway maintenance. This study aims at evaluating the mechanical …

Ground penetrating radar (GPR) has been applied for ballast layer inspection for two
decades, mainly for the analysis of ballast layer fouling levels. However, some issues that …

To facilitate rapid, accurate, and convenient detection of ballast fouling, this paper proposes
simplified computational models based on thermodynamic principles to analyze the surface …

Tamping is an effective maintenance measure for ballasted track, but it can also cause
ballast breakage and sleeper abrasion. To balance the advantages and disadvantages of …
