Monitoring Track Transition Zones in Railways [PDF]

open access: yesSensors, 2021
This manuscript presents the first measurement program and data collection on the Dinatrans track transition solution after it was installed in a track section in the north of Spain (Galicia). The Dinatrans solution was created to address the limitations

Structural Health Monitoring of Railway Transition Zones Using Satellite Radar Data [PDF]

open access: yesSensors, 2018
Transition zones in railway tracks are locations with considerable changes in the rail-supporting structure. Typically, they are located near engineering structures, such as bridges, culverts and tunnels.

Monitoring the Geometric Position of Transition Zones to Increase the Quality and Safety of Railway Lines

open access: yesApplied Sciences, 2022
Transition zones on railway lines are localities with gradual changes in the construction layers in the connections between a fixed track and ballasted track or between a wide track and various railway objects, e.g., tunnels, bridges, culverts, etc.

Spatial and Temporal Variations of Freezing and Thawing Indices From 1960 to 2020 in Mongolia

open access: yesFrontiers in Earth Science, 2021
Mongolia is one of the most sensitive regions to climate change, located in the transition of several natural and permafrost zones. Long-term trends in air freezing and thawing indices can therefore enhance our understanding of climate change. This study

Viability Study of the Application of Bi-Block Concrete Sleepers as a Solution for Technical Landfills

open access: yesApplied Sciences, 2022
Transition zones, specifically embankment structures on railway tracks, are recurrently damaged by high-speed rail traffic, thus producing abrupt variations in the track vertical stiffness.
