Investigating the Influence of Auxiliary Rails on Dynamic Behavior of Railway Transition Zone by a 3D Train-Track Interaction Model

Latin American Journal of Solids and Structures
Abrupt track vertical stiffness variations along railway tracks can lead to increased dynamic loads, asymmetric deformations, damaged track components, and consequently, increased maintenance costs.

Technology on Snow and Ice: Innovation, Monitoring, and Performance for the Olympic Winter Games Milano Cortina 2026

Scandinavian Journal of Medicine &Science in Sports, Volume 36, Issue 2, February 2026.
ABSTRACT Elite performance in Olympic winter sports depends on the interplay among the athlete, equipment, and the snow or ice. This naturally evolves with temperature, humidity, wind, preparation, and contact between the equipment and its surface. Together, these factors continuously rebalance the forces of gravity, aerodynamic drag, and friction ...

Track Bed Gaps Impact on Ballast Particle Surrounding Flow Field and Aerodynamic Forces for High-speed Railways before and after Ballast Splashing

Chengshi guidao jiaotong yanjiu
[Objective] When high-speed trains operate on ballasted tracks, the complex airflow field around ballast particles can lead to track ballast splashing. The formation mechanism of this phenomenon remains unclear.

Dynamic Comparison of Conventional Ballasted Track Versus Ballasted Ladder Track

, 2015
In railway transport system there is a continuous demand for railway capacity enhancement. In order to meet the demands in many countries more axle load and higher speed of the train is applied. As a result of these the track responses are becoming big issues that have a great effect on track service. Therefore to develop and utilize appropriate tracks

Photovoltaic Power and Meteorological Datasets With Snow Detection From the Outdoor Solar Power Laboratories of the Finnish Meteorological Institute

Geoscience Data Journal, Volume 13, Issue 1, January 2026.
We describe and publish high‐resolution solar power (PV) output, ancillary, and meteorological data from three high‐latitude sites in Finland during 2015–2021. We performed quality control and daily snow cover classification on the modules based on numerical data and photographs. Snow coverage on PV modules was found to vary significantly based on site
