Introduction
Friction management using solid or fluid (oil, grease, etc.) substances at the wheel-rail interface is a
complex subject and includes:
— lubrication of the wheel flange/ rail gauge corner interface, commonly referred to as “flange or rail
lubrication”;
— lubrication of the back of flange/ check rail interface; commonly referred to as “check rail
lubrication”;
— altering the level of friction at the interface between the top of rail and the wheel tread, commonly
referred to as “top of rail friction management”;
— applying materials to the wheel rail contact to increase (improve/ enhance/ recover) adhesion.
This document sets out requirements for the application for the adhesion materials. It describes systems
fitted on board trains and on the track, as both systems may need to be employed to achieve effective
adhesion.
Managing the wheel-rail interface effectively will reduce wear of both wheel and rail and ensure reliable
braking performance. 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 reaching their full economic potential.
There needs to be control in the application of adhesion materials such that there is:
— no loss of traction or braking performance;
— no adverse effect on signalling systems or track circuits;
— no harmful environmental effect;
— no incompatibility between the different lubricants/materials in use, particularly, between solid and
fluid systems;
— no effect on the performance of the infrastructure.
1 Scope
This document is limited to specifying the requirements when applying adhesion material to the interface
between the wheel tread and the crown of the rail, and includes both trainborne and trackside solutions.
This document only covers the equipment and application of adhesion material to the active interface.
This document defines:
— the characteristics that systems for the application of adhesion materials of the 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 adhesion materials of the wheel-rail interface.
This document only applies to the mainline railway.
NOTE 1 This document can also be used for other railways, e.g urban rail.
NOTE 2 Where technologies are used to influence the wheel/rail interface, other than the application of a
material, this document is out of scope but can be used as guidance.
