BS EN 15427:2008+A1:2010 Railway applications. Wheel/rail friction management. Flange lubrication

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”
  • Friction modification of the top of rail / wheel tread interface, commonly referred to as “top of rail friction management”.

This document sets out requirements for the lubrication of the wheel flange / rail gauge corner only. It describes systems fitted on board trains and on the track, as both systems may need to be employed to achieve effective lubrication of the wheel-rail interface.

Managing the wheel-rail interface effectively will reduce wear of both wheel and rail. When friction is managed effectively, noise levels, energy consumption 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 lubrication such that there is no:

  • Loss of traction or braking performance
  • Adverse effect on signalling systems or track circuits
  • Intolerable increased risk of fire
  • Harmful environmental effect
  • Incompatibility between the different lubricants in use, particularly, between solid and fluid systems.

This document is limited to specifying the requirements when applying lubricants to the wheel-rail interface between the wheel flange and the rail gauge corner (active interface) either directly or indirectly to the wheel flange or to the rail, and includes both trainborne and trackside solutions.

This document defines:

  • The characteristics that systems of lubrication 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 lubrication of the wheel-rail interface
