Track Inspection Data‐Driven Identification and Localization of Interlayer Debonding in Slab Tracks Using a Tile‐Coding Neural Network

Structural Control and Health Monitoring, Volume 2026, Issue 1, 2026.
Interlayer damage is a critical issue affecting the structural integrity and service performance of high‐speed railway slab tracks. Traditional track inspection data‐driven identification methods often rely on manual feature extraction and are limited by insufficient utilization of temporal and multisource inspection data, resulting in limited accuracy

An assessment method of rail corrugation based on wheel–rail vertical force and its application for rail grinding

, 2023
In practice, the assessment and treatment of rail corrugation are quantitatively based on the corrugation depth. Wheel–rail vertical forces (WRVF), as a direct reflection of wheel–rail interaction, can give expression to the corrugation depth and thus ...

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

Influence of Sleeper Distance on Rail Corrugation Growth

, 2018
Rail corrugation is commonly found in most railway tracks worldwide. However, there is no solution to stop corrugation from growing. Therefore, to minimise corrugation growth, this paper aims to model, analyse, and predict rail corrugation growth under ...

High‐Entropy Energy for Self‐Powered Systems

SmartSys, Volume 1, Issue 2, June 2025.
ABSTRACT In energy constrained application scenarios, self‐powered systems (SPSs) are gradually emerging as a core technological pathway for enabling distributed intelligent sensing. High‐entropy energy, such as micro‐wind, vibrations, water motion, and human activity, is widely available but difficult to harness due to its low density, randomness, and

They put me on a train: Assimilation and the Australian railways

Geographical Research, Volume 63, Issue 2, Page 249-259, May 2025.
This article explores the South Australian railways’ involvement in the forcible removal of Aboriginal children from their families and homes. It gives close attention to the artwork and words of First Nations peoples who were taken away from their families by train under the Australian government policy of Assimilation. A key finding is that while the
