New Insights from Multibody Dynamic Analyses of a Turnout System under Impact Loads
Applied Sciences, 2019 A railway turnout is an essential infrastructure for managing railway traffic flexibility. In contrast, it imposes restrictions on train operations such as lower operational speeds through the turnout due to the complex movements of trains over the ...

Geometrical layouts of railroad switches applying single turnouts
Transportation Overview - Przeglad Komunikacyjny, 2017 In the article there were included issues of geometrical layouts of railroad switches “in design” by applying single turnouts which are components of technical research of turnouts. During rebuilding railroad switches it is required to project a new geometry by a correct selection of kinematic and geometrical parameters.

Dynamic Performance of Concrete Turnout Bearers and Sleepers in Railway Switches and Crossings [PDF]
Advances in Civil Engineering Materials, 2018 Abstract With constant changes of their geometry and alignment, wheel–rail forces, and track and operational parameters, railway infrastructures are exposed to nonlinear actions by nature. A detrimental type of loading condition that causes cracking in the railway concrete bearers in switches and crossings is the dynamic transient wheel ...

The political economy of the Prussian three-class franchise [PDF]
, 2019 How did the Prussian three-class franchise, which politically over-represented the economic elite, affect policies? Contrary to the predominant and simplistic view that the system allowed the landed elites to capture most political rents, we find that ...

Strength through diversity: how cancers thrive when clones cooperate
Molecular Oncology, EarlyView.Intratumor heterogeneity can offer direct benefits to the tumor through cooperation between different clones. In this review, Kuiken et al. discuss existing evidence for clonal cooperativity to identify overarching principles, and highlight how novel technological developments could address remaining open questions.

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