Frost Heaving in Ballast Railway Tracks
Procedia Engineering, 2017 Abstract Frost heave is a well-known phenomenon in cold regions. It may happen in the wet clayey ground during winter in seasonally frozen regions and during autumn to winter in active layers in permafrost regions. The railway track upheaval, which happens in cold regions, is generally understood as due to frost heaving in subgrade layers.

Real-Time Inspection System for Ballast Railway Fasteners Based on Point Cloud Deep Learning
IEEE Access, 2020 Rail fasteners are the most numerous components in railways and they should be inspected periodically. Manual inspection is currently a common solution, which is laborious and low-efficient. Some automatic inspection approaches are proposed.

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 ...

Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT The rapid development of new railway networks and the aging of existing infrastructure in seismic‐prone regions continue to motivate the need for efficient methods to simulate the dynamic behavior of coupled train track structure systems. While detailed train–structure interaction (TSI) models can capture complex mechanisms, they are often too

Settlement Response of Fibre Reinforced Railway Ballast
, 2016 Ballasted track is the prevalent track form worldwide and with good design and maintenance can satisfy high performance demands including those of high speed lines. However, increasingly onerous loading is being placed on existing ballasted track networks in many parts of the world by more frequent, longer, faster and heavier trains.

Multi‐level fatigue reliability assessment of reinforced concrete railway bridges
Structural Concrete, EarlyView.Abstract This paper presents a multi‐level reliability framework for assessing the fatigue life of reinforced concrete (RC) railway trough bridges subjected to cyclic loading. The framework incorporates increasing levels of analytical complexity and real‐world data in four steps. First, an analytical model applies S–N curves and the Palmgren–Miner rule

The Economic History Review, Volume 79, Issue 1, Page 57-88, February 2026.Abstract This paper contributes to the understanding of the complex relationship between British economic performance during the Napoleonic wars and the ‘West Indies’, as the Caribbean slave colonies were called. Not only did profits from slave‐based commerce provide financing for the growth of the financial sector, as has been claimed, but the risk of

Discrete Element Analysis of Shape Effect on the Shear Behaviors of Ballast
Scientific Reports, 2023 Railway ballast layer is an indispensable component of railway transport. Ballast morphology plays an important effect in ballast-sleeper interaction and the durability of ballast layer.

Analytical Frameworks and Theories of Electric Power in Non‐Linear Circuits
IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.Based on the challenges of distorted currents and non‐linear components in modern power grids, this article reviews seminal electrical power theories that seek to generalize the traditional definitions of active, reactive, and apparent power. It provides a detailed analysis of their mathematical foundations, practical implementation, and validity.
