Essentially, a slab track consists of a concrete slab placed on a subbase over prepared subgrade. The rails may be directly fastened to the concrete slab or the rails may be placed on concrete blocks or another slab system that is placed (or embedded in) the underlying concrete slab.
Modelling of slab track systems for design purposes
Oct 3, 2023 · In this paper, a proposed slab track design model has been introduced to evaluate the nonlinear behavior of the most common slab track systems (BÖGL, Shinkansen, and RHEDA 2000) in order to design/analysis these systems and to select the most structurally efficient slab track system in the world.
slab track design for high speed lines. The approach is based on the dynamic analysis of a slab track and a number of performance factors calculated on the basis of the results of the dynamic simulations.
A holistic design approach For high speed railway lines with a velocity of up to 300 km/h, slab track systems provide good performance and durable riding quality. Intense teamwork and strong cooperation between civil engineers and geotechnical engineers is required in order to ob-tain a reliable design of the slab track systems. Designing ballast -
In this paper, state-of-the-art simulation models are employed to illustrate and address the needs for innovative requirements in terms of structural integrity and robustness, life cycle cost (LCC) and environmental footprint of new and existing slab track designs.
This paper aims to propose a new slab track design model which can be used to design/analyze any slab track systems under vertical loads using AREMA and EN specifications for high‐speed systems (300 kmph).
Development of a new design methodology for slab track systems
Feb 14, 2024 · This paper aims to develop a new methodology for estimating the rail deformations for the most common slab track systems (BÖGL, Shinkansen, and RHEDA 2000. This methodology yielded the first design aid for slab track systems based on design equations and graphs for high-speed systems.

Thus, the main scope of this paper is to predict the structural behavior for slab track design purposes with special focus on the configurations present in the Chauconin case study located in the French high-speed line LGV- Est (StedefTM system).
Presently high-speed tracks are built on a large scale. Although ballasted tracks are still popular, more and more slab tracks are constructed. They have some significant advantages such as low maintenance, high availability, low structure height, and low weight.
