Slab Track Mass-Spring System

Transportation Research Record: Journal of the Transportation Research Board, 2012
Development of a ballastless slab track structure with a mass-spring system began about 20 years ago, and different kinds of these track systems have been successfully in use for urban transportation systems. With these systems the elastic elements are inserted under the slabs to provide protection from bothersome vibration and noise.

Concrete Slab Track State of the Practice

Transportation Research Record: Journal of the Transportation Research Board, 2001
Railway track technology has evolved over a period of 150 years since the first railroad track on timber ties was introduced. For much of this period, the conventional track system, commonly referred to as the ballasted track system, has consisted of certain components including rails, ties, ballast, and the subgrade (roadbed).

LCA comparison of slab track vs. ballasted track

International Conference on Road and Rail Infrastructure
When it comes to reducing the rail systems' ecological footprint, it is essential to assess and compare lifecycle (LC) greenhouse gas (GHG) emissions. In the presented study this is executed for the two main railway track construction types: ballasted track and slab track.

The noise radiated by ballasted and slab tracks

Applied Acoustics, 2019
Abstract Conventional railway track is supported by a layer of crushed stones known as ballast. In recent years concrete slab tracks have been introduced which have been used widely in the construction of high-speed lines. However, a particular concern is that slab track is considered to be noisier than ballasted track.

The Influence of Track Parameters on the Sound Radiation from Slab Tracks

2021
The influence of track parameters on the sound radiation has so far mainly been studied for ballasted tracks. The increasing usage of slab tracks in new railway lines worldwide makes a review of these parameters relevant. In this paper, the structural vibrations of rail and slab are evaluated based on two waveguide finite element models that are ...

Feste Fahrbahn : Slab Track

2005
Seit bald 200 Jahren rollt die Eisenbahn auf dem Dreiklang Schiene, Schwelle und Schotter. Für sehr hohe Fahrgeschwindigkeiten, Brücken und lange Tunnels sind mittlerweile schotterlose Alternativen entwickelt worden, deren Anwendung auf "normalen" Strecken diskutiert wird.

Track Instrumentation for Digital Twin Development in Urban Slab Track Structures

International Conference on Road and Rail Infrastructure
The development of public transport in Zagreb has significantly advanced through novel tramway infrastructure solutions, addressing the growing demands of an expanding urban network. With rising passenger numbers and increased loads combined with higher operating speeds, a clear need for track structures offering superior resistance to wear, geometry ...

Floating track slab isolation for railways

Journal of Sound and Vibration, 1977
Where an underground railway is in existence, it is up to the developer to take what precautions may be necessary to provide an acceptable interior environment. Many a building has been isolated on resilient bearings from the ground-borne vibrations produced by an adjacent railway with the result that the occupants are unaware of the trains running ...

Structural Optimization and Performance Analysis on the Slab of the Unit Slab Track System

2012
According to the structural mechanical characteristics of unit ballastless track and the spatial demand of the bridge with criss-cross beams, geometric optimizations were carried out on the slab track.4 T-type bosses are installed around the slab track instead of circular convex in the middle, which lead the slab to adopt to the bridge with criss-cross
