Optimally configured wheel flange lubrication systems can supply as many as 250 axles. A large number of motor cars with wheel flange lubrication provide the requis-ite lubrication for the rail network. This is the basis on which wheel flange lubrication systems can achieve the desired effect.

Proper control of lubrication has been shown to be a powerful agent in reduction of rail gauge face and wheel flange wear. Fuel savings are also possible through lubrication of curved and tangent ...
SKF wheel flange and top-of-rail lubrication systems substantially contribute to reduced wear, friction and noise. Intelligent lubrication systems can support rail operators in achieving higher profitability through less wear and, as a consequence, reduced maintenance costs and higher fleet availability.
Successful lubrication depends on the use of the right type of metering element (for example nozzles or spray heads), particularly in relation to: oil + air lubrication systems external minimal quantity lubrication systems; chain lubrication systems railway wheel flange lubrication systems
Wheel Flange Lubrication and Rail Head Maintenance Systems For all rail vehicles, from freight trains to streetcars, wear on the wheels and the rail is a major maintenance factor. The noise generated by wheels on tracks, especially in curves, adds environmental problems to the service needs of rail equipment.

The objective of this study was to investigate the influence of contaminants on the tribological behavior of wheel–rail contact. Sand, phosphate, sulfur, and cement were the studied contaminants identified after a Tunisian railway expertise.
The tiny contact zone (approximately 1 cm 2) where steel wheel meets steel rail is fundamental to rail transport.This work is a comprehensive presentation of recent research in wheel–rail contact tribology. It stresses that, unlike gears or rolling bearings which are sealed contacts with reduced exposure to the surrounding environment, a wheel–rail contact is an open system that is exposed ...
For many years, CONDAT has been developing biodegradable oils and greases intended for wheel-flange lubrication. Non toxic and 100% synthetic, these lubricants are applied using on-board distribution devices or fixed systems at the sides of railtracks.These lubricants provide a significant reduction in noise and wear.

Wheel Rim and Wheel Flange Lubricators. Wear at the wheel/rail interface affects all rolling stock. Proven to reduce wear due to friction and also minimising operational noise, Morgan rim and flange lubricator sticks are engineered to provide topical lubrication at
Wheel flange/rail gauge corner contact lubrication: Tribological investigations ... the laboratory test developed in this study allows to investigate wheel flange/rail contact lubrication. The main advantages of such laboratory tests are, on the one hand, they permit the precise control of local contact conditions while, on the other hand, they ...
Flange lubricators apply lubrication to the flange of the locomotive wheel which reduces surface friction. cn.ca Des graisseurs de boudins de roues appliquent de la graisse sur les boudins des roues de locomotive, ce qui réduit la friction entre le rail et les roues des wagons.
SKF wheel-flange lubrication systems have been used by railway companies for many decades. In a number of applications, these companies have impressively verified the effectiveness of wheel-flange lubrication systems. Such systems reduce track resistance, wear, and save energy.
The wheel wear prediction is a key-topic in the field of railway research as it has big impact on economical and safety aspects of trainset design, operation and maintenance. The aim of this work was to implement a flexible and pre-dictive railway

2004 (English) In: Proceedings of the 14th International Wheelset Congress, 2004 Conference paper, Published paper (Other academic) Abstract [en] This paper addresses some aspects of modelling and validation of wheel wear simulation. In previous work at KTH the influences of braking and lubrication have been accounted for through empirically estimated average scaling factors.
SKF EasyRail wheel flange lubrication and top-of-rail conditioning systems are mounted on-board on the first leading vehicle axle. When activated, air and lubricant are fed from the grease tank to the spray nozzle. The lubricant is sprayed to the wheel flange in a thin layer and transferred to the gauge face of the rail by direct contact.
