This document (FprCEN/TS 15427-1-2:2020) has been prepared by Technical Committee

This document is part of the series EN 15427, Railway applications - Wheel/Rail friction

Friction management using solid or fluid (oil, grease, etc) substances at the wheel-rail interface is a

— lubrication of the wheel flange / rail gauge corner interface, commonly referred to as “flange or

— lubrication of the back of flange/ check rail interface, commonly referred to as “check rail

— altering the level of friction at the interface between the top of rail and the wheel tread,

— applying materials to the wheel rail contact to increase (improve/ enhance/ recover) adhesion.

This document sets out the requirements for the equipment and application of the top of rail

wheel/rail friction management. It describes systems fitted on board trains and on the track, as both

systems may need to be deployed to achieve effective friction management of the wheel-rail

Managing the wheel-rail interface effectively will reduce wear of both wheel and rail. When friction

is managed effectively, noise levels, wear levels and the risk of flange climbing are reduced.

Conversely, where not managed effectively, assets may require replacement prematurely before

There needs to be control in the application of top of rail materials such that there is:

— no incompatibility between the different lubricants/ materials in use, particularly, between solid

This document is limited to specifying the requirements when applying material to the active

interface between the wheel tread and the crown of the rail and includes trainborne and track side

This document only covers the equipment and application of material to the active interface.

— the characteristics that systems of top of rail equipment for wheel-rail interface shall achieve,

together with applicable inspection and test methods to be carried out for verification;

— all relevant terminology which is specific to the application of top of rail materials of the wheel-
