Study on the effect of mitigation strategies for rail corrugation in metro lines
Rail corrugation appears as a periodic irregularity on the rail running surface that causes severe dynamic loads at the wheel-rail interface. These dynamic forces may generate ground-borne vibrations that propagate from the line to the surrounding ...

Rail corrugation growth on curves - measurements, modelling and mitigation
, 2015 The development of rail corrugation (so called rutting corrugation) on a 120 m radius curve on the metro of Stockholm Public Transport was studied by field measurements, laboratory measurements and numerical simulations.

Wear-type rail corrugation prediction: Field study
, 2006 Rail corrugation consists of undesirable periodic fluctuations in wear on railway track and costs the railway industry substantially for it's removal by regrinding. Much research has been performed on this problem, particularly over the past two decades,

The Interaction Between Railway Vehicle Dynamics And Track Lateral Alignment
This thesis examines the effect of vehicle dynamics on lateral deterioration of the track alignment. As rail traffic runs along a route, the forces imposed upon the track cause the ballast to settle, and hence the track geometry deteriorates.

Mechanism of Inner Rail Corrugation on Large-Radius Curves in Metro Systems
LubricantsThis paper investigates the underlying cause of inner rail corrugation on large-radius curved tracks in metro systems. A dynamic model of the vehicle–track system (VTS) was developed to analyze the creep characteristics between the guiding wheelset and ...

The effect of non-uniform train speed distribution on rail corrugation growth in cornering
, 2015 Rail corrugation is a significant problem in railway engineering, manifesting as an oscillatory wear pattern on the rail head. These profile variations induce unwanted vibrations, excessive noise and other associated problems. Uniformity in train passing
