Impact of wheel shape on the vertical damage of cast crossing panels in turnouts [PDF]

open access: yes, 2015
Impact forces generated in the load transfer area of railway crossing panels lead to a range of degradation modes from wear and fatigue of the contacting materials, fatigue of supporting components to ballast/subgrade deterioration.

Pickin' up good vibrations: a systematic review of footfall detection and analysis in the realm of wildlife surveying

open access: yesWildlife Biology, EarlyView.
Exploration of new wildlife surveying methodologies that leverage advances in sensor technology and machine learning has led to tentative research into the application of seismology techniques. This, most commonly, involves the deployment of a footfall trap – a seismic sensor and data logger customised for wildlife footfall.

Integrating Dynamics and Wear Modelling to Predict Railway Wheel Profile Evolution [PDF]

open access: yes, 2003
The aim of the work described was to predict wheel profile evolution by integrating multi-body dynamics simulations of a wheelset with a wear model. The wear modelling approach is based on a wear index commonly used in rail wear predictions.

Quantification of human‐caused mortality in an imperiled turtle

open access: yesWildlife Biology, EarlyView.
For many threatened and endangered species, the importance of human‐caused mortality relative to other sources has not been quantified, making it difficult to assess the effectiveness of mortality‐reduction strategies. We used radio telemetry data, pooled across studies at protected sites in the US states of Illinois and Wisconsin, to estimate natural ...

Winter Track Survey of the Amur Tiger (Panthera tigris altaica) in the Southwest Primorsky Province of Russia 俄罗斯滨海边疆区西南部东北虎 (Panthera tigris altaica) 冬季足迹调查

open access: yesWildlife Letters, EarlyView.
In the winter of 2021/2022, a winter track survey revealed 43–46 tigers (without cubs) in 5.4 thousand km2 of suitable habitats in the Southwest Primorsky Province of Russia. In the same period, a network of camera traps registered 54 adult/subadult tigers here.

Development of micro-ribbed wheel tread profile of railway vehicle for reducing steady lateral force on curve

open access: yesNihon Kikai Gakkai ronbunshu, 2014
It’s generally known that tangential force of wheel/rail interface which depends on a change of coefficient of friction between wheel and rail has a big influence on a steady lateral force of railway vehicle.

ON THE INSTABILITY OF THE RAILWAY VEHICLES

open access: yesFiabilitate şi Durabilitate, 2011
The railway vehicles have two sources of instability. The most common is the hunting induced by the reversed conic shape of the rolling surfaces of the wheels. The other one is related by the anomalous Doppler effect that can occurs when the train velocity exceeds the phase velocity of the waves induced in the track structure.
