Tests of geosynthetics-reinforced ballast stressed state under heavy trains [PDF]
MATEC Web of Conferences, 2019 Nowadays requirements for strength and stability of railway subgrade are increased. It occurs due to raising of train speed and axle load. Some sections of subgrade that were previously considered stable do not satisfy safety requirements. In this regard,

Experimental Study on Settlement Behavior of Ballasted Tracks with Polymer Compound-Coated Gravel
Applied Sciences, 2022 The ballast used in ballasted railway tracks transmits load from the rails and ties to the subgrade during train travel, and directly affects the overall track support performance and elastic behavior of the ballasted track.

Rigid Body Dynamics of Railway Ballast [PDF]
, 2003 A method for the discrete particle simulation of almost rigid, sharply edged frictional particles, such as railway ballast is proposed. In difference to Molecular Dynamics algorithms, the method does not require knowledge about the deformation-force law of the material.

A Global Account of Established Non‐Native Fish Species
Global Change Biology, Volume 31, Issue 8, August 2025.This study compiles the most complete global database of non‐native fish species that have successfully established themselves in new freshwater and marine environments. It documents 1535 species across 193 countries, identifies their main introduction routes—such as aquarium trade, aquaculture, and artificial waterways—and highlights that many ...

Journal of Traffic and Transportation Engineering (English ed. Online)Railway ballast is easily contaminated by different fouling material and the fouled ballast always causes the deterioration of railway track. Many previous studies focused on the effect of a certain kind of fouling material on ballast performance, but ...

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

Treatment and recovery of contaminated railway ballast [PDF]
TURKISH JOURNAL OF ENGINEERING AND ENVIRONMENTAL SCIENCES, 2014 Experimental tests of metal extraction from stones sampled from articially contaminated railway ballasts are presented and discussed. Metal extraction was performed by washing with aqueous solutions of disodium ethylenedi- aminetetraacetate (EDTA), at selected concentrations. The eectiveness of the remediation process was evaluated using leaching tests.

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.

Statistical analysis of cone penetration resistance of railway ballast
EPJ Web of Conferences, 2017 Dynamic penetrometer tests are widely used in geotechnical studies for soils characterization but their implementation tends to be difficult. The light penetrometer test is able to give information about a cone resistance useful in the field of ...
