Railway Defect Detection Method: A Review

Abstract

The railway is indeed one of the main transportations means in the world. However, with the rapid development and advancement of the railway industries, more railways accidents occur mainly due to its defects which result in economic losses. Traditionally, the railway defect detections process which is deems to be dirty, difficult and dangerous are done manually by the railway maintenance workers. In the recent years, many sophisticated equipment such as portable detectors, track inspection trolleys, track comprehensive inspection vehicles, etc had been developed. This article outlines two main mode of inspection namely static and dynamic inspection, which are commonly used in the railway defect detection and maintenance work. Furthermore, the railway inspection equipment used by the major countries are summarized and the impact on railway inspection based on deep learning and artificial intelligence are appropriately predicted.

Mechanism-driven improved SVMD: an indirect approach for rail corrugation detection using axle box acceleration

“…Similar to high-speed railways, urban rail vehicles may encounter abnormal vibrations during operation due to structural damages [2,3]. Originating from track or vehicle issues, these vibrations can have adverse effects on both passenger comfort and train performance [4,5]. As urban rail transit continue to evolve, the identification of rail defects becomes increasingly crucial, especially for ensuring railway safety amidst advancements in vehicle speed and load.…”
