Comparative Evaluation of Railway Ballast Degradation
FUOYE Journal of Engineering and Technology, 2022 Ballast bed is one of the most important components of ballasted railway track system. Over a period of service, it undergoes axial deformation due to the accumulation of train cyclic loading. However, there has not been a universally accepted method of evaluating ballast degradation, hence, this study focused on comparing two most common methods ...

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.

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

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.

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 12, December 2025.ABSTRACT Understanding the impact of human activities on fish communities is critical for the effective conservation of Amazonian ecosystems. In this study, we sampled environmental DNA (eDNA) from 17 sites (lakes and rivers) in two Peruvian national reserves, Pacaya‐Samiria and Allpahuayo‐Mishana, using a metabarcoding approach with four genetic ...

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 ...

Toward Zero Waste Mining: Circular Economy of Copper Slags
Global Challenges, Volume 9, Issue 12, December 2025.Mining and metal extraction processes generate over 90% of global waste. With the rapid increase in population and urbanization, the demand for geotechnical applications and construction materials constantly increases and can absorb the entire quantity of slags generated.

Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 27, Page 4797-4823, 14 November 2025.Abstract Predicting changes in track irregularity after tamping is important for assisting maintenance decisions and improving construction efficiency. To date, most prediction methods lack consideration for the uncertainties related to tamping effects.
