Improving the performance of railway tracks through ballast interventions

, 2018
Maintenance and eventual renewal of a ballasted track constitute major operational costs for a railway network. Thus, significant benefits would accrue from a more robust track design having a longer service life and reduced maintenance requirements ...

Parallel computing aided analyses of dynamic buckling for railway track infrastructure

Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 19, Page 2943-2968, 5 August 2025.
Abstract This paper presents a scalable parallel computing framework for simulating track buckling under dynamic train loads, enabling large‐scale railway track stability analysis. A three‐dimensional (3D) track model is developed using finite element‐based Euler–Bernoulli beam formulations for rails, dynamic force inputs, and nonlinear interactions at

MODELING THE RAILWAY TRACK BALLAST BEHAVIOR WITH HYPOPLASTICITY

Journal of Mathematical Sciences
Abstract The contact problem describing a railway vehicle — road — track ballast system is under our investigation. During the motion, the rolling stock (snowpiercer) is represented by a moving localized load, the road by a Timoshenko beam, and the track bed material is rigorously modeled using 3-by-3 matrices of stress and strain ...

Biological Flora of Britain and Ireland: Cytisus scoparius*

Journal of Ecology, Volume 113, Issue 7, Page 1877-1933, July 2025.
Broom is an attractive and common native plant across Britain, Ireland and most of Europe, and yet it is considered a harmful and invasive weed around the rest of the world. This is aided by broom thriving on poor dry soils, helped by using green stems for photosynthesis and having root nodules to fix nitrogen.

Laboratory experimental of ballast–bituminous–latex–roving (Ballbilar) layer for conventional rail track structure

Journal of the Mechanical Behavior of Materials
Ballast structures continue to be utilized in Indonesia’s railway system. They are essential for conventional railway lines, which experience high levels of stress and are susceptible to damage from train traffic. This study examined the utilization of a

Dynamic effect of high speed railway traffic loads on the ballast track settlement [PDF]

, 2011
The traditional ballast track structures are still being used in high speed railways lines with success, however technical problems or performance features have led to non-ballast track solution in some cases.

Generalization of anomaly detection in bridge structures using a vibration‐based Siamese convolutional neural network

Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 18, Page 2751-2768, 18 July 2025.
Abstract Corrosion is one of the main damages in steel bridges, which appears as a loss of material and sectional area and causes member failure over time. A reliable bridge management system not only should help in preventing catastrophic structural failure by employing an in‐time anomaly detection approach for all the bridges within a network but ...

Modelling rail track deterioration and maintenance: current practices and future needs [PDF]

, 1997
As commercialisation and privatisation of railway systems reach the political agendas in a number of countries, including Australia, the separation of infrastructure from operating business dictates that track costs need to be shared on an equitable ...

Study of ballast layer stiffness in railway tracks

Građevinar, 2016
In this paper, ballast layer stiffness in railway tracks is investigated. Test results show that the percentage of ballast contamination changes considerably across the ballast layer depth.
