The wheel-rail system operates in an open environment where the weather condition varies
constantly. In this laboratory study, an investigation using a pin-on-disc tribometer placed in …

A novel test method has been used to study how applied and natural lubrication (leaf and
humidity) influences the coefficient of friction in the wheel-rail contact. A pin-on-disc …

A wheel/rail system is an open system, where the operating environment factors, such as
atmospheric humidity, temperature, and oxidation behavior, are subject to change. This …

A series of experiments on the wheel/rail traction coefficient were carried out with a twin disc
rolling contact machine by varying the surface roughness and the temperature of the wheel …

Railways operate in an open environment where temperature, humidity, and the oxidation
conditions are subjected to change. An experimental investigation used a pin-on-disc …

The wheel-rail contact is a safety critical interface. Wear, particle emission and adhesion are
all wheelrail contact phenomena and are discussed here. All three phenomena are material …

Incidents involving low levels of adhesion between the wheel and rail are a recurrent issue
in the rail industry. The problem has been mitigated using friction modifiers and traction …

Purpose–The aim of this study is to calculate the coefficient of friction of wheel/rail interface
in both water lubrication and dry friction conditions. Design/methodology/approach …

In high-speed railways, adhesion between wheel and rail is a very important function to
maintain safety and stable operation from the standpoint of braking and driving, in particular …

In addition to contaminants such as dirt, precipitation and leaves, iron oxides are constantly
present on railway wheel and rail surfaces. Iron oxides potentially influences adhesion and …
