22、ease, 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
23、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. Managin
24、g 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 the
25、ir 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 th
26、e different lubricants in use, particularly, between solid and fluid systems.

It is generally used to apply lubricant to the wheel. The m
38、ost effective use of lubricant is achieved by installation of lubricating equipment on wheelsets close to the leading end of a train. This ensures that all the subsequent active interfaces between train wheels and rails are lubricated. The optimum position for this equipment is on the leading wheels
39、et, but space limitations may preclude this. The area of implementation and the lubrication system shall be defined and agreed by the customer. NOTE If required, further wheelsets may be equipped with trainborne equipment. 4.1.2 The trainborne equipment shall be designed to optimize lubrication of t
40、he active interface and limit contamination of any other part of the train or infrastructure. Build up of excess lubricant on the train should be avoided to reduce the risk of fire. 4.1.3 Solid lubricants that are used in the form of, for example stick application on to the flange, may eject part of
41、 the stick as debris. The size of any piece of debris should be kept to a minimum. NOTE It is suggested that the mass of any piece of debris should be no greater than 5 g.

42、 (E) 8 4.2 Selection of trainborne equipment 4.2.1 In selecting the trainborne equipment, the following shall be taken into account as a minimum: ambient temperature range and climatic conditions (see EN 50125-1); equipment positioning; space constraints; availability of pneumatic and electrical sup
43、plies; speed; options for system control and lubricant regulation; interface with other on-board systems; the type of lubricant; compatibility between different lubricants used by the Railway Undertaking; total life cycle cost and maintainability. 4.2.2 A technical file shall be compiled setting out
44、 verification criteria and compliance. 4.2.3 A description of types of Lubricant Application Unit currently available is given in Annex A. A list of reasons for fitting trainborne equipment is given in C.1. 4.3 Design of trainborne equipment 4.3.1 The position and alignment of each Lubricant Applica
45、tion Unit shall take into account suspension movements to ensure application of lubricant to the active interface (see 4.5), at all conditions within the trains operational limits, and the need to gain access for maintenance. See C.2 for some positioning and alignment information. 4.3.2 The trainbor
46、ne equipment shall be designed to meet the vibration and shock loads requirements of EN 61373 and EN 13749 relevant to the position on the vehicle. 4.3.3 The design shall: incorporate a stated fatigue load case appropriate for the intended service life of the equipment; provide protection to the equ
47、ipment from flying objects e.g. track ballast and snow and ice; ensure the security of fixing against vibration. NOTE Account should be taken of the effects of turbulence of surrounding airflow at service speeds on the performance of the application system. 4.3.4 The Lubricant Application Unit shall
48、 be adjustable such that it can be returned to its correct working position (see 4.5) following wheel reprofiling or other maintenance changes. 4.3.5 The capacity of the system shall take into account the intervals between maintenance opportunities. Consideration may be given to providing a means to
49、 determine when refilling is required.
