Maintenance Methodologies Embraced for Railroad Systems: A Review

Advances in Materials Science and Engineering, 2022
Congestion on land, hike in fuel costs, and critical need to cut down environmental emissions have generated the urge to shift from conventional rail transit systems to metro rail and high-speed rail for a mass mode of transportation.

Dynamic effect of high speed railway traffic loads on the ballast track settlement [PDF]

, 2011
The traditional ballast track structures are still being used in high speed railways lines with success, however technical problems or performance features have led to non-ballast track solution in some cases.

A 2.5D coupled FE-BE model for the prediction of railway induced vibrations [PDF]

, 2010
Ground vibrations induced by railway traffic at grade and in tunnels are often studied by means of two-and-half dimensional (2.5D) models that are based on a Fourier transform of the coordinate in the longitudinal direction of the track.
