3.8 trackside equipment lubrication system installed on or adjacent to the track
4 Requirements for trainborne equipment 4.1 General 4.1.1 The trainborne equipment shall apply lubricant to take effect in the active interface as described in 4.5. It is generally used to apply lubricant to the wheel. The most 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 wheelset, 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 the 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 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. SIST EN 15427:2008

4.3.4 The Lubricant Application Unit shall 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 determine when refilling is required. SIST EN 15427:2008

4.6 Verification The application of lubricant to the active interface shall be verified by the following means in Table 1. Table 1 - Verification Requirement Check When carried out System fitted to train Yes/no Documentation check Near front of train Yes/no Documentation check Design check – Lubricant Application Unit shown applying lubricant to active interface Yes/no Documentation check Physical check – Lubricant Application Unit applies lubricant to active interface Yes/no By static test and inspection Check of control equipment as required:  distance;
 time;  angle;  cant;  curve. To operate in accordance with customer requirement. During train testing
This does not exclude other requirements referenced in Clause 4, or specified by the customer. As the effectiveness of the system cannot be verified immediately, 4.7 is to be used to optimize the effectiveness of the system. SIST EN 15427:2008

4.7.3 After the passage of the train over a section of track, traces of lubricant shall be verified as described below: i) As set out in 4.5 and in Figure 1, lubricant shall be evident in areas “L” and “M” and shall be permitted in area “K”. Traces of migrated lubricant are permissible into area “N”, close to the border with “M” with the agreement of the relevant parties. ii) As set out in 4.5 and Figure 2, lubricant shall be evident in area “B” and shall be permitted in area “A”. Traces of migrated lubricant are permissible into area “C” close to the border with “B” with the agreement of the relevant parties. 4.7.4 The lubrication system shall be adjusted in accordance with the manufacturer’s instructions to ensure that the performance is optimized to deliver the requirements set out above. 4.7.5 The supplier of the trainborne equipment shall provide maintenance instructions for the equipment. These shall include a method for fault diagnosis to check that the trainborne equipment is not partially or fully blocked or misaligned, see C.3. 4.7.6 The railway undertaking shall have a maintenance plan for the lubrication system. These documents shall regulate the in-service performance of the lubrication system and shall ensure that all components are securely attached to their mountings. 4.7.7 This maintenance plan should include monitoring of lubricant usage as a method of checking effective delivery. The maintenance plan shall be reviewed and amended according to service experience. 4.7.8 After wheelset change or reprofiling, or other adjustments to the trainborne equipment, the Lubricant Application Unit shall be checked to ensure correct alignment (see 4.5 and 4.7.3) in accordance with the supplier’s instructions. 5 Requirements for trackside equipment 5.1 General 5.1.1 The trackside equipment shall apply lubricant to take effect in the active interface as described in 5.5. The trackside equipment shall ensure that all active interfaces between the train wheels and rails are lubricated throughout the intended length of the rail to be lubricated. 5.1.2 The trackside equipment shall be designed, installed and maintained to optimize lubrication of the active interface and limit contamination of any other part of the train or infrastructure. Build up of excess lubricant on the Lubricant Application Unit, trackbed or trains shall be avoided to reduce the risk of fire. It may also lead to problems with maintenance. SIST EN 15427:2008

5.2.1 The trackside equipment shall meet the specified requirements for application over the full range of operating conditions. These shall include as a minimum local conditions relating to:  track curvature and gradient;  ambient temperature range and climatic conditions (see EN 50125-1);  equipment positioning for access and space constraints;  availability of power supplies;  options for system adjustment, control and lubricant regulation;  type of lubricant;  total life cycle cost and maintainability;  wheel and rail profiles, permitted wheel and rail wear, axle loads and train spe
