Railway superstructure for high-speed rails [PDF]

open access: yesActa Polytechnica CTU Proceedings, 2021
The construction of the track is solved as a conventional (with track ballast) or as a ballastless track (without track ballast). When deciding on the choice of the most suitable track design for high-speed rail, it is necessary to emphasize that with ...

Experimental Study on Vibration Characteristics of Unit-Plate Ballastless Track Systems Laid on Long-Span Bridges Using Full-Scale Test Rigs [PDF]

open access: yesSensors, 2020
In this work, we present a series of hammering tests on full-scale unit-plate ballastless tracks used for long-span bridges. There is no denying that it is a new attempt to pave ballastless tracks on high-speed railway long-span bridges; the related ...

Fatigue damage analysis of ballastless slab track in heavy-haul railway tunnels

open access: yesUnderground Space, 2022
A ballastless slab track, which is commonly used in the track structures of heavy-haul railway tunnels, was analysed based on field measurement data of the Fuyingzi Tunnel on the Zhangtang Railway.

Determination of the rail-to-earth transition resistance of the ballastless track and influence of the resistance on the current spreading in the subgrade [PDF]

open access: yesВестник Научно-исследовательского института железнодорожного транспорта, 2022
Introduction. The rail-to-earth transition resistance is an important parameter of electrified railways, which directly effects the electrical safety level of the traction network and the potential distribution in the upper structure track area.

Ballastless railway track transition zones: An embankment to tunnel analysis [PDF]

open access: yesTransportation Geotechnics, 2022
Railway track transition zones are characterised by an abrupt change in track support stiffness, which increases dynamic wheel loads and leads to the acceleration of differential settlement and track degradation. The performance of transition zones is a concern for railway Infrastructure Managers due to the increased maintenance operations and costs ...

Influence of temperature gradient of slab track on the dynamic responses of the train-CRTS III slab track on subgrade nonlinear coupled system [PDF]

open access: yesScientific Reports, 2022
Temperature is an important load for ballastless track. However, there is little research on the system dynamic responses when a train travels on a ballastless track under the temperature gradient of ballastless track.
