Introduction EN 50126-1 is likely to enhance the general understanding of the issues involved in achieving RAMS characteristics within the railway field. It defines a comprehensive set of tasks for the different phases of a generic life cycle for a total rail system. Although some of the examples given in the annexes of EN 50126-1 are for rolling stock, the standard is essentially aimed as a top level railway system document. RAMS characteristics for rolling stock (i.e. its long term operating behaviour performance), as for any other system, forms an important part of its overall performance characteristics. But the consideration of RAMS, in contractual terms, between a customer / operator and a Main Supplier for the procurement of rolling stock has been problematic. Also, in rolling stock contracts, there is now a greater emphasis on the impact on end customers of service failures and on the economic and risk considerations of RAMS (i.e. the business perspective). Consequently, Life Cycle Cost is being used as a measure of satisfying customer needs and providing a wider perspective of RAMs importance in terms of the business economics. Life Cycle Cost approach represents a holistic, total cost of ownership philosophy for addressing the economic considerations. The contribution of RAMS to the LCC of rolling stock could be used to allow the economic considerations to be addressed. This application guide focuses mainly on the procurement issues, from the tender to the operation phase, and is intended to help in establishing a common approach for capturing the different, time dependant, performance requirements of rolling stock from an operator/business perspective. EN 50126-1 is a standard, which treats the overall aspects of RAMS in Railway Applications. This guide deals with the application of RAM part of EN 50126-1 to rolling stock only, as stated in the Scope and clarifies areas where EN 50126-1 could be misinterpreted. Entities Involved In the Life Cycle Phases of Rolling Stock: Depending on the organisational and management structure of the railway system concerned, a number of entities, performing different functions, may be involved within the life cycle phases of rolling stock. For the purpose of guidance on contractual relations, the entities are divided into 2 main categories, i.e. customer and supplier. It is therefore advisable, to identify all the entities that can be a part of this relationship and to examine how the responsibilities of dealing with these entities are shared between the customer and supplier relationship. Table 1 gives some typical examples only: Table 1 Possible sharing of responsibility Entity Supplier responsibility Customer responsibility Main supplier of the rolling stock X Sub supplier of the rolling stock X Operator of the rolling stock X Owner of the rolling stock X Maintainer of the rolling stock X X CLC/TR 50126-3:2006 5 ? 1 Scope This document provides guidance on applying the RAM requirements in EN 50126-1 to rolling stock and for dealing with RAM activities during the system life cycle phases from invitation to tender to demonstration in operation only. All references to EN 50126-1 concern the version of 1998. The guide is aimed at the customers/operators and main suppliers of rolling stock. The main purpose of the guide is to: enable a customer/operator of rolling stock: to specify the RAM requirements addressing the type of operation in terms of the end customer needs, considering service availability and economic considerations; to evaluate different tenders, in terms of RAM requirements, on a common basis with the aid of specific RAM documents; to gain assurance, during design/development phase, that the rolling stock being offered is likely to satisfy the RAM contractual requirements by examining step by step detailed and specific RAM documents as an output of the RAM activities performed during the development phase; to validate that the rolling stock, as delivered, satisfies the specified RAM requirements to enable the main supplier of rolling stock to understand the customers/operators RAM requirements to provide substantive information/visibility in a tender to show that the product offered is likely to satisfy the RAM requirements by performing preliminary RAM analysis; to provide substantive information during design/development phase to show that the product offered is likely to satisfy the RAM requirements by performing detailed RAM analysis; to demonstrate that the product delivered satisfies the RAM requirements; 1.1 Limitation of scope Regarding Safety, this application guide is restricted to providing, for reference purposes only, a list of the most common rolling stock Hazards associated with an operation. Regarding LCC (Life Cycle Cost), this application guide is restricted to providing only the key RAM parameters necessary to be incorporated into an LCC Model. This application guide excludes: RAM values connected to the different RAM requirements (however, it contains a simple guide line of actions for supporting the decision making process and choosing appropriate values, see 5.4) specific RAM documents to be produced and activities to be performed. However, it provides, only as an example, typical data and document templates for recording the output of a RAM analysis). 2 Definitions For this guide, the in EN 50126-1 and the following apply: 2.1 Part Number the alphanumeric code, generally assigned by the Main Supplier, to represent a family of items with the same characteristics of Form, Fit and Function. CLC/TR 50126-3:2006 6 ? 3 Approach adopted for the Guide The approach adopted is to raise the following questions, for each phase of the Life Cycle, in order to successively set up the requirements of EN 50126-1 and the basis for satisfying them: WHAT: what activities / tasks are to be performed and the supporting documents to be produced? WHO: who has the responsibility for these activities / tasks? HOW: which type of method or tool should be used? This process is adopted for the development of the guide and should be applied in accordance with the structure of the application guide. 4 Application of this Guide 4.1 Object of the application This document is applicable to rolling stock (train, coach, locomotive, etc) and to all the subsystems, assemblies and parts belonging to the rolling stock, according to their boundary limits. Referring to 1.2 of EN 50126-1, the Guide is for use by Railway Authorities and the railway support industry and is applicable to: new rolling stock modification/refurbishment of existing rolling stock For use in this document only, the above two bullet point items should be referred to by the generic term “system”, comprising the complete sequence “system, sub-system, component” of a rolling stock or the whole rolling stock itself breakdown structure. 4.2 Application of EN 50126-1 4.2.1 Assessment of the application of EN 50126-1 Referring to 5.3 of EN 50126-1 and taking into account the responsibilities of the different entities involved in the life cycle phases, the following section gives a synthesis of the main actions required to meet the requirements. According to 5.3.2 of EN 50126-1, the assessment of the application of the requirements of EN 50126-1 to rolling stock (system under consideration) shall be defined by the Railway Authority and according to 5.3.4 of EN 50126-1, the assessment shall: 1 Speci
