7 NEN-EN 14198:2014 Ontw. pren 14198:2014 (E) 1 Scope This document specifies basic requirements for the braking of trains hauled by locomotives including individual vehicles operating on routes of the European railways and their infrastructure systems. It is also applicable for trains in fixed or predefined formation with conventional brake system architecture. Units designed to be operated in fixed formations only should follow the requirements for brake systems as specified for high speed trains (EN ) or as specified for multiple units (pren ). The specific requirements in this document take into account the historical development and formalisation into UIC-leaflets with regard to the traditional air brake, and their further development with regard to the incorporation of additional electrical and electronic control functions. Furthermore they take into account the specification and integration of additional brake systems like dynamic brakes and adhesion independent brakes. This document also takes into account that the system architecture is formed by components and subsystems which have been specified and further developed by UIC leaflets and EN standards. Nevertheless these specific requirements for locomotive hauled trains and others addressing the air brake and attached systems are enveloped by more generic functional and safety requirements for a main brake system which applies for any brake system architecture. These overall generic requirements are put at the very beginning of the design requirements in 5.3, and then followed by the specific requirements of the traditional air brake system, the so called "EN-UIC" brake. The brake system requirements which are specific for on-track machines are set out in EN This document covers all new vehicle designs. It is not intended to be retrospectively applied to existing vehicle designs. 2 Normative References The following referenced documents are indispensable for the application of this document.

Braking also provides the immobilisation of a train either for a certain period of time or permanently when it is not in operation or without any energy on board. Units designed and assessed to be operated in general operation (various formations of vehicles from different origins; train formation not defined at the design stage) shall be fitted with a technically compatible brake system to ensure the brake function in all vehicles of the train. 5.2 General safety requirements Design principles The design, construction or assembly, maintenance and monitoring of safety-critical components, and more particularly of the components involved in train movements, shall ensure safety at the level corresponding to the aims laid down for the respective railway network. The braking techniques and the stresses exerted shall be compatible with the design of the tracks, engineering structures and signalling systems. Brake systems shall conform to the following: the design principles listed in the standards on brake systems referred to in Clause 2 normative references; the brake performances defined in Clause 6; the design principles in accordance with the requirements of this standard; keeping within the specified effects on the infrastructure, particularly regarding EMC. In the course of the system design risks shall be considered and mitigated. As a minimum, the following hazards shall be taken into account: a) the brake force applied is greater than the maximum design level: impact on track shifting forces; excessive jerk (impact on standing passengers); significant damage to the contact surface of the wheels or friction partners; impact on load assumptions in the fatigue life of the components generating the brake force. b) the brake performance is lower than the level of brake demanded: keeping traction effort on the train while emergency brake is requested; required emergency brake performance not achieved; 9

12 pren 14198:2014 (E) NEN-EN 14198:2014 Ontw. required parking brake performance not achieved; holding brake performance not achieved. c) there is no brake force when demanded: no emergency brake on the whole train when requested; automatic (emergency) brake not initiated in the case of an unintended train separation (loss of train integrity); parking brake: loss of performance over the time. d) there is a brake force when a brake demand has not been made: undue local brake application (pneumatic or parking). brake component failures that could cause death or injury or damage to the train or infrastructure, e.g. derailment. The hazards in the previous list shall be assessed in accordance with CSM. Concluding from the hazards listed above the emergency brake shall have a high level of integrity and shall always be available when the brake system is set up for operation, whereas the service brake, whilst it may share subsystems and components, etc. with the emergency brake, need not achieve the same level of integrity. Nevertheless the service brake shall be designed to comply with the following requirements: it shall be activated on the whole train when requested; it shall cut off traction effort on the whole train while service brake is requested; it shall provide service brake effort as high as requested. Independently from the service brake: it shall be possible for the driver to immediately initiate the emergency brake by using the same lever which is used for service braking or by using another independent device; the train protection systems shall be capable of initiating the emergency brake. The required performance levels for different train categories are given in Clause 6 and Annex A. The compliance of these performance levels of the brake system shall be fully demonstrated during type tests. The components shall be of a proven design and withstand any duties expected to occur during their period in service. The safety implication of any failures shall be limited by appropriate means; as described in this standard. For more guidance on proven design see Annex C. Single point failures shall not cause any relevant malfunctions regarding emergency brake application. Proper functionality of the brake system is also affected by the design of the piping and component design as specified in Fire protection The brake system shall be protected against the effects of fire and shall not emit toxic fumes. This shall be achieved by selecting appropriate materials, by an appropriate system architecture and installation arrangement. 10
