In recent years, railway infrastructures and systems have played a significant role as a highly
efficient transportation mode to meet the growing demand in transporting both cargo and …

Railway track health monitoring and maintenance are crucial stages in railway asset
management, aiming to enhance the train operation quality and service life. For this aim …

Track degradation and defects of existing passenger and freight mixed railroads are
concentrated in bridge–embankment transition zones. Heavy axle load (HAL) operation on …

Track transitions such as bridge approaches, road crossings and shifts from slab track to
ballasted track are common locations where track degradation accelerates due to dynamic …

Differential settlement of ballast and subgrade is a common issue in ballasted railway tracks.
In transition zones between two different track forms, such as between a ballasted track and …

As a core infrastructure of high-speed railways, ballast layers constituted by graded crushed
stones feature noteworthy particle movement compared with normal railways, which may …

High-speed trains running on ballasted tracks intensify the vibration of ballast layers to a
greater extent than conventional passenger trains, with detrimental effects to train …

Concrete tub crossings are at-grade railroad crossings used primarily on low-speed and low-
tonnage rail lines. Concerns have been raised about the stiffness differential present …

High-speed railways are very important in global transportation. However, the railway
subgrade is significantly affected by the environment due to its exposure to the atmosphere …

This paper presents a methodology for monitoring transition zones using responses of
multiple-axle box acceleration (multi-ABA) measurements. The time–frequency …
