RailNet: Railway Track Anomaly Detection via Image Processing With Hybrid Deep Learning Techniques

open access: yesIET Image Processing, Volume 20, Issue 1, January/December 2026.
Our model leverages a DenseNet121 backbone combined with advanced neural network layers to achieve high accuracy in identifying and classifying track defects. The dataset, consisting of images of railway tracks with and without faults, was rigorously augmented to enhance model robustness.

A comparison on the effects of coal fines and sand fouling on the shear behaviors of railway ballast using large scale direct shear tests

open access: yesJournal 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 ...

Railway Track Fault Classification for Predictive Maintenance Using Deep Learning Algorithms Based on a 2D Train‐Track‐Bridge Interaction Model

open access: yesIET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.
A deep learning framework integrated with a 2D train track bridge simulation model is developed to classify corrugation and ballast faults from vibration signals using time frequency analysis. The method achieves high accuracy and supports predictive maintenance for railway infrastructure.

Photovoltaic‐Assisted Energy Optimization for High‐Speed Train Performance in South Africa Intercity Electric Rail Corridors

open access: yesThe Journal of Engineering, Volume 2026, Issue 1, January/December 2026.
ABSTRACT Decarbonizing the intercity rail in sub‐Saharan Africa requires the use of energy architectures that go beyond traditional grid reliance at the expense of traction performance. This paper introduces a novel photovoltaic (PV)‐assisted hybrid traction topology for a 42 km Pretoria–Sandton rail corridor in South Africa, where between‐rail PV ...

Novel use of geosynthetics to increase the confinement of railway track ballast layer [PDF]

open access: yesE3S Web of Conferences
Insufficient confining pressure in railway ballast leads to particle rotation, degradation, and excessive deformation. Enhancing lateral confinement improves track stiffness and reduces both resilient and permanent deformations, which is particularly ...

Influence of Asphalt Emulsion Stabilization on Pavement Structural Behavior and Life Cycle Assessment (LCA)

open access: yesAdvances in Civil Engineering, Volume 2026, Issue 1, 2026.
Assessing pavement sustainability requires jointly evaluating structural performance and environmental impacts, yet these dimensions are often analyzed separately. This study proposes an integrated framework combining mechanistic–empirical pavement design and life cycle assessment (LCA) to quantify the structural–environmental trade‐off associated with

Railway ballast

open access: yes, 2022
Railway ballast is normally made of crushed rocks with grading (particle size distributions). Ballast is inevitably suffering from more rapid degradation. Because ballast keeps undergoing and dissipating most of the train loadings, furthermore, the train

Ballast Contamination Mechanisms: A Criterial Review of Characterisation and Performance Indicators

open access: yesInfrastructures, 2020
Across the world, ballasted railway tracks are utilised extensively due to their cost efficiency, ease of drainage, and capacity to withstand cyclic imposed loadings from heavy trains.

Experimental Characterization and Numerical Performance Assessment of Treated Cinder Gravel for Base Course Applications

open access: yesAdvances in Civil Engineering, Volume 2026, Issue 1, 2026.
This study investigated the suitability of natural cinder gravel blended with fine‐crushed aggregates as a base course pavement material using laboratory tests and numerical simulations. Laboratory test results for natural cinder gravel indicated that cinder gravel alone failed to meet the Ethiopian Roads Authority (ERA) standard specifications for ...

Identification of dynamic properties of a flooded ballast layer using impact excitation technique and minimization algorithm

open access: yesJournal of Infrastructure Preservation and Resilience
In recent times, the railway sector has faced a pressing need to expand its railway network, resulting in the widespread adoption of ballasted tracks. These tracks are favored for their ease of construction, making them a cost-effective solution for the ...
