Rail tracks undergo massive stresses that can affect their structural integrity and produce rail
breakage. The last phenomenon represents a serious concern for railway management …

Defects in the rails can affect the operational safety of the railway. In order to examine the
knowledge structure of the research about the ultrasonic testing of rail defects, a systematic …

Surface defect inspection of no-service rail is important for safety of railway transportation.
However, there are several challenges of irregular defect boundary, similar foreground and …

Railway infrastructure monitoring is a vital task to ensure rail transportation safety. A rail
failure could result in not only a considerable impact on train delays and maintenance costs …

Alongside the development of high-speed rail, rail flaw detection is of great importance to
ensure railway safety, especially for improving the speed and load of the train. Several …

The unavoidable increase in train speed and load, as well as the aging of railway facilities,
is requiring more and more attention to rail defects detection. As a promising tool for rail, in …

In this paper, a decision support approach is proposed for condition-based maintenance of
rails relying on expert-based systems. The methodology takes into account both the actual …

Pipes have multiple applications in daily life and they are subjected to different types of
defects. Nonlinear guided wave has attracted significant attention in detecting …

A continuous increase in the worldwide demand for high-speed traffic, freight tonnage as
well as of the train operating frequency is worsening the decay conditions of many railway …

A multi-robot-based fault detection system for railway tracks is proposed to eliminate manual
human visual inspection. A hardware prototype is designed to implement a master–slave …
