The spread of non‐native species
Biological Reviews, Volume 101, Issue 3, Page 1197-1234, June 2026.ABSTRACT The global redistribution of species through human agency is one of the defining ecological signatures of the Anthropocene, with biological invasions reshaping biodiversity patterns, ecosystem processes and services, and species interactions globally.

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 7, Page 1514-1532, June 2026.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

Rail Track Maintenance Planning: An Assessment Model [PDF]
, 2000 In Australia, railway track maintenance costs comprise between 25-35 percent of total freight train operating costs. Track maintenance planning models have been shown to reduce maintenance costs by 5 to 10 percent though improved planning.

CRITICAL TEMPERATURE ON CURVED SUPERELEVATED RAILWAYS
ce/papers, Volume 9, Issue 1, Page 342-351, April 2026.Abstract Railways are essential for the efficient transport of people and cargo, but they face increasing risks due to temperature variations. This study analyses thermal instability in continuously welded rails located on curves with superelevation.

Measuring the area and number of ballast particle contacts at sleeper/ballast and ballast/subgrade interfaces [PDF]
, 2015 The number of railway ballast particles in contact with a sleeper may be relatively small. The discrete and non-uniform nature of these contacts may cause breakage and wear.

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

The interaction between railway vehicle dynamics and track lateral alignment [PDF]
, 2016 Track geometry deteriorates with traffic flow, thus it needs to be regularly restored using tamping or other method. As the deterioration is mainly in the vertical direction this aspect has been widely studied and models for its analysis developed ...
