5 Introduction Background The implementation of the Technical Specifications for Interoperability (TSIs) mandated through a series of European Directives has resulted in a review of all requirements mandated in Railway Group Standards. Under the Strategy for Standards Management, RSSB has given a commitment to review all of its standards with a view to mandating only those requirements that define the interface and the need for cooperation between different categories of duty holder to manage risk safely. A review of the requirements set out in standards associated with hot Axlebox detection has resulted in a revision of this Railway Group Standard. GE/RT8270 mandates requirements and responsibilities for the assessment of compatibility between infrastructure and rolling stock. Where existing infrastructure has not been assessed as conforming to the applicable Infrastructure TSIs, conformity with the requirements of GE/RT8014 is a method of demonstrating compatibility between rolling stock and hot Axlebox detection systems.

6 The requirements in the TSIs for Axlebox Condition Monitoring are supported by BS EN 15437-1:2009. To align with Europe the relevant parts of BS EN 15437-1:2009 that are appropriate for GB are incorporated within this document. Principles The requirements of this document are based on one or more of the following principles: a) This document mandates those requirements that define the interface and the need for cooperation between different categories of duty holder to manage risk safely. b) This document mandates requirements that are necessary to support an open point in a TSI and meet an essential requirement of the relevant European Directive. Support to essential requirements The European Directives applicable to interoperability mandate that each TSI is required to address a number of essential requirements. In supporting specific open points in rolling Stock TSIs, including the as yet unpublished Conventional Rail Locomotives and Passenger rolling Stock TSI, the essential requirements set out in are addressed.

General requirements Safety The design, construction or assembly, maintenance and Monitoring of safety critical components, and more particularly of the components involved in train movement must be such as to guarantee safety at the level corresponding to the aims laid down for the network, including those for specific degraded situations.

8 Reliability and availability The Monitoring and maintenance of fixed or moveable components that are involved in train movements must be organised, carried out and quantified in such a manner as to maintain their operation under the intended conditions . Technical compatibility The technical characteristics of the infrastructure and fixed installations must be compatible with each other and with those of the trains to be used on the rail system .

9 Or b) Be fitted with an onboard axle bearing Monitoring system which shall monitor all of the affected axle journal bearings. rolling stock that have an operating speed equal to or greater than 250 km/h shall be fitted with an onboard axle bearing Monitoring system which shall monitor all of the axle journal bearings. The rolling stock interface to infrastructure rolling stock shall be designed in accordance with the rolling stock prohibited zone requirements set out in clause of BS EN 15437-1:2009, and have either: a) No heat source, other than that generated by an in-service axle journal bearing, located within the boundaries of the prohibited zone. Or b) Thermal shielding of any heat source, other than that generated by an in-service axle journal bearing, located within the boundaries of the prohibited zone. To facilitate the setting of temperature alarm levels for trackside HABDs, the railway undertaking shall make available to the infrastructure manager when requested, the normal maximum temperatures of the target zones for the rolling stock that they operate (see ).

10 rolling stock fitted with onboard axle bearing Monitoring system The onboard axle bearing Monitoring system shall be set to initiate an alarm to indicate that acceptable conditions are exceeded. The conditions that trigger alarms shall be determined and set by the railway undertaking responsible for the rolling stock on which the onboard axle bearing Monitoring system is fitted. When an alarm is triggered, the onboard axle bearing Monitoring system shall provide an indication of which axle journal bearing(s) triggered the alarm and shall initiate the following actions: a) On passenger carrying rolling stock the driver shall be alerted. b) On non-passenger carrying rolling stock either the driver shall be alerted or the train brakes shall be automatically applied to bring the train to a stand in a controlled manner.
