Effect of temperature gradient-induced periodic deformation of CRTS Ⅲ slab track on dynamic responses of the train-track system [PDF]

open access: yesRailway Sciences
Purpose – Temperature is an important load for a ballastless track. However, little research has been conducted on the dynamic responses when a train travels on a ballastless track under the temperature gradient.

Modelling of slab track systems for design purposes

open access: yesJournal of Engineering and Applied Science, 2023
Slab track is a recent technology used to cope up with the train high axle loads and speed, it has replaced the ballast material in classical ballasted track with either reinforced concrete slab or asphalt layer in order to increase both stability and ...

Influence of slab length on dynamic characteristics of subway train-steel spring floating slab track-tunnel coupled system

open access: yesLatin American Journal of Solids and Structures
A subway train-steel spring floating slab track-tunnel coupling dynamic model, considering short and middle-long wavelength random track irregularities, and longitudinal connection between adjacent slabs of steel spring floating slab track, was developed.

Quality of Slab Track Construction – Track Alignment Design and Track Geometry [PDF]

open access: yesCivil and Environmental Engineering, 2015
Abstract The slab track superstructure design (without ballast) is a perspective construction especially for building tunnels and bridges in the modernized sections of railway tracks in Slovakia. Monitoring of the structure described in this article is focused on the transition areas between standard structure with ballast and slab ...

A STUDY ON THE WHEELSET/SLAB TRACK VERTICAL INTERACTION [PDF]

open access: yesFiabilitate şi Durabilitate, 2012
This paper deals with the interaction between a moving wheelset and a slab track due to the short-pitch corrugated rail. The wheelset is modeled using a free-free Timoshenko beam with attached rigid bodies as the axle boxes, wheels and brake discs.

Identification of Temperature-Induced Deformation for HSR Slab Track Using Track Geometry Measurement Data. [PDF]

open access: yesSensors (Basel), 2019
Slab track is widely used in many newly built high-speed rail (HSR) lines as it offers many advantages over ballasted tracks. However, in actual operation, slab tracks are subjected to operational and environmental factors, and structural damages are ...

Slab track optimisation considering dynamic train–track interaction [PDF]

open access: yes, 2021
Slab track is a type of railway track that is frequently used e.g. in high-speed applications as an alternative to ballasted track. Slab track is also well suited on bridges and in tunnels since no ballast is required and the cross-section of tunnels can be reduced. Slab tracks generally have lower maintenance demands than ballasted track.
