The coefficient of friction between a wheel tread and the top of the rail should be maintained at intermediate levels to limit frictional tangential contact forces. This can be achieved by applying top-of-rail products. Reducing the coefficient of fr

For the development of rail materials with improved properties regarding rolling contact fatigue and wear, it is at first important to know and understand the loading conditions in railway operatio...

Predicting the behaviour of trains when braking under low adhesion conditions presents considerable challenges. This paper describes an approach to the problem using a model of the full train braking system known as LABRADOR (Low Adhesion Braking Dyn

This paper presents a new approach for modelling the wear in wheel-rail contacts for a wide range of test and contact conditions (material pairing, load, creep, lubrication etc.) in the mild and severe wear regimes with one set of model coefficients.

In this work, the authors present a methodology for assessing running gear with respect to rolling contact fatigue of wheels and rails. This assessment is based on the wheel/rail contact data of different wheel profile wear states obtained from a whe

Train operators report low adhesion in autumn, which they suspect is caused by fallen leaves on a track surrounded by forest and farmland. To investigate and quantify this effect, vehicle tests have been performed in autumn on a track partially surro

With the current lack of a wheel/rail creep force model that simulates the performance of a top-of-rail (TOR) product as a third body layer, this study aims to develop a model for a friction modifier. Pick-up, carry-on and consumption behaviours of t

Fatigue crack propagation (FCG) experiments performed on a fully pearlitic steel subjected to severe plastic deformation are presented. The steel was deformed by high-pressure torsion to study the influence of applied strain and specimen orientation
