An Accurate and Fast Method to Inspect Rail Wear Based on Revised Global Registration

IEEE Access, 2018
Rail wear inspection is vitally important in the railway industry. Conventional methods mainly use manual or static measurements to detect rail wear, which are inefficient, imprecise, and unreliable.

Review of Catenary Icing on High‐Speed Railways: Characteristics, Impact and Countermeasures

High Voltage, EarlyView.
ABSTRACT The pantograph–catenary system (PCS) is the only path for electrified railway trains to acquire energy. Catenary icing during winter is a common natural phenomenon, which usually leads to the deterioration of the current quality and severely affects the operational safety of trains.

The development of rail-head acoustic roughness

, 2009
A model of the development of rail-head acoustic roughness on tangent track has been formulated. The model consists of a two-dimensional time domain wheel-rail interaction force calculation, with the normal force used as the input to a two-dimensional ...

Rolling contact fatigue, wear and broken rail derailments

, 2015
Rolling contact fatigue (RCF) and wear are inevitable in the wheel/rail system, but resulting failures and derailments need not also be inevitable. Understanding why and under which conditions broken rails and derailments are likely to occur will focus ...

Carbody sway behaviour of railway vehicles due to track irregularity from rail alternate side wear

Railway Engineering Science
Track irregularity from rail alternate side wear is manifested as uneven rail wear waveforms alternating in the left and right rails with equal intervals, which will cause carbody sway behaviour of railway vehicles and greatly influences the passenger ...

The wear resistance research of the rail contact surface depending on the grinding process

Mechanics and Advanced Technologies, 2019
Background. Continuous mechanical loads on the rails during its contact with the wheel lead to an accumulation of residual stresses in the surface layers of the rails, resulting in fast-growing fatigue cracks.

Change and Continuity in British Politics: Can the Starmer Government's Approach to Governance Resolve the Crisis in the British State without Radical Reform?

The Political Quarterly, Volume 96, Issue 1, Page 140-148, January/March 2025.
Abstract In this article, the key dilemmas that will confront the new Labour administration in Britain during its initial period in power are examined. The Starmer government is seeking to use the state pragmatically to improve British economic performance, stem the crisis in public services and strengthen the strategic capacity of Whitehall.

Geometry and stiffness optimization for switches and crossings, and simulation of material degradation

, 2010
A methodology for simulating wear, rolling contact fatigue, and plastic deformation for a mixed traffic situation in switches and crossings (S&C) has been developed.

A Very Social History: South American Cricketing Tourists in Britain in 1932

History, EarlyView.
Abstract Drawing on both the rich Anglophone cricket historiography and the new Latin American sports scholarship, this article maps out the entangled global networks that shaped the tour of Britain made in 1932 by a team of South American cricketers.

Wheel surface damage: relating the position and angle of forces to the observed damage patterns [PDF]

, 2012
A new method of presenting simulated wheel/rail forces and relating these to the observed wheel damage has been developed. This indicates a good correlation between the predicted forces and the regions of the wheel where damage is observed in practice.
