Correlating track forces and track profile
, 2006 Wheel/rail dynamic forces are dependent upon the characteristics of both train and track, and lead to time-dependent degradation of the track. The quality of maintenance of both train and track affect the amplitude of these forces and therefore the rate ...

The behaviour of railway level crossings: insights through field monitoring
The development of reliable methods for measuring deflections as trains pass has enabled valuable insights into railway track behaviour to be gained.

An empirical rail track degradation model based on predictive analysis of rail profile and track geometry [PDF]
, 2010 It is generally observed that the condition of rail tracks degrades rapidly over time until and unless effective maintenance is carried out. In the rail industry, rail maintenance actions are usually reactive, which means that maintenance is carried out ...

Advanced Engineering Materials, EarlyView.A distinct semi‐confined inner‐tube chemical vapor deposition geometry enables reproducible, large‐area growth of phase‐pure 2D β′‐In2Se3 from InI + Se precursors. Engineering local vapor transport and optimizing precursor delivery and temperature–time conditions yield uniform continuous films.

A computational procedure for prediction of ballasted track profile degradation under railway traffic loading [PDF]
, 2015 A computational procedure is developed in the present paper, allowing the prediction of the ballasted track profile degradation under railway traffic loading. In this procedure, an integration of the short-term and long-term mechanical processes of track

Advanced Engineering Materials, EarlyView.Aluminum and nitride coatings are used in industry because they are hard, resist wear, and protect against oxidation. Adding boron can improve friction behavior and other properties. This study tests coatings on surfaces with different finishes. Results show smoother surfaces perform better, while rough ones wear faster, although coatings can reduce ...

Degradation of railway track on heavy haul lines
, 2008 The geometric alignment of railway track deteriorates with time, primarily due to the static and dynamic forces exerted by the trains’ wheels on the track. Deterioration of the track’s geometry is called track roughness. The paper reports on the outcomes

Advanced Engineering Materials, EarlyView.This study shows that superalloys used in aircraft engine disks become much more prone to deformation at high temperatures if they have been strained during manufacturing. This effect increases with the level of prior strain but eventually reaches a limit.
