What is BS EN 50126-1:2017-Railway Applications – The Specification and Demonstration of Reliability, Availability, Maintainability and Safety (RAMS)-Generic RAMS Process
BS EN 50126-1:2017- Railway Applications is a part of a series of standards developed by the European Committee for Electrotechnical Standardization (CENELEC) for railway applications. This particular standard, provides guidelines for implementing a generic process for managing the reliability, availability, maintainability, and safety (RAMS) of railway systems.
Moreover, the standard covers the entire life cycle of a railway system, from its conception to its disposal. It defines a systematic approach to RAMS management that includes the identification and evaluation of hazards, the analysis of the system’s RAMS requirements, and the development of RAMS targets and plans. The standard also provides guidance for the implementation of RAMS measures and the monitoring and reporting of RAMS performance.
Furthermore, primary objective of the standard is to ensure that railway systems are designed, constructed, operated, and maintained in a safe, reliable, and efficient manner. It provides a framework for the systematic identification and management of hazards and risks associated with railway systems, and for the continuous improvement of RAMS performance over the entire life cycle of the system.
Overall, BS EN 50126-1 is intended for use by railway system owners, operators, designers, manufacturers, and other stakeholders involved in the development and operation of railway systems. It is applicable to all types of railway systems, including mainline, urban, and industrial railways, as well as rolling stock, signalling, and communication systems.
Requirements of BS EN 50126-1:2017
Hazard Identification: The standard requires that hazards associated with the railway system be identified systematically. The identification process includes the identification of hazards at the system and subsystem levels. The standard also requires that the identified hazards be documented and evaluated for their severity.
Risk Analysis: This standard requires that risks associated with the identified hazards be analyzed. This process includes identifying the causes and consequences of the hazards and evaluating the likelihood and severity of the risks associated with them. The standard also requires that risk analysis be carried out at the system and subsystem levels.
RAMS Requirements Specification: The standard also requires that RAMS requirements be specified for the railway system based on the results of the hazard identification and risk analysis. The RAMS requirements include the reliability, availability, maintainability, and safety requirements of the railway system.
RAMS Targets: This standard requires that RAMS targets be set for the railway system based on the RAMS requirements. The targets include the reliability, availability, maintainability, and safety targets for the railway system.
RAMS Plan: The standard requires that a RAMS plan be developed for the railway system based on the RAMS targets. The plan includes the RAMS measures that will be implemented to achieve the RAMS targets. The plan also includes the RAMS verification and validation activities that will be carried out to ensure that the RAMS targets are met.
RAMS Measures: This standard requires that RAMS measures be implemented to achieve the RAMS targets. The RAMS measures include design measures, operational measures, and maintenance measures.
RAMS Verification and Validation: The standard requires that RAMS verification and validation activities be carried out to ensure that the RAMS targets are met. The activities include RAMS analysis, RAMS testing, and RAMS monitoring and reporting.
Overall, BS EN 50126-1:2017 provides a systematic approach to managing the RAMS of railway systems, and ensures that railway systems are designed, constructed, operated, and maintained in a safe, reliable, and efficient manner.
Benefits of BS EN 50126-1:2017
Improved Safety: The primary objective of BS EN 50126-1 is to ensure the safe operation of railway systems. The standard provides a systematic approach to identifying and managing hazards and risks associated with railway systems, which leads to improved safety for passengers and personnel.
Increased Reliability and Availability: The standard requires the specification of RAMS requirements and targets, as well as the implementation of RAMS measures. This ensures that the railway system is designed, constructed, and operated to meet the required levels of reliability and availability.
Enhanced Maintainability: This standard requires the implementation of measures of RAMS that include maintenance measures. This ensures that the railway system is designed and constructed with maintainability in mind, leading to easier maintenance and reduced downtime.
Better Performance Monitoring: The standard requires the implementation of RAMS verification and validation activities, which includes RAMS monitoring and reporting. This enables the continuous monitoring and reporting of the performance of the railway system, leading to better performance management and continuous improvement.
Regulatory Compliance: Compliance with BS EN 50126-1:2017 is mandatory in Europe for the management of the RAMS of railway systems. Implementing the standard ensures compliance with regulatory requirements and reduces the risk of non-compliance.
In summary, BS EN 50126-1:2017 provides several benefits to railway system owners, operators, designers, manufacturers, and other stakeholders involved in the development and operation of railway systems. The standard ensures the safe, reliable, and efficient operation of railway systems, leading to improved performance, reduced risk, as well as regulatory compliance.
Who needs BS EN 50126-1:2017-Railway Applications – The Specification and Demonstration of Reliability, Availability, Maintainability and Safety (RAMS)?
Railway System Owners: Organizations that own the railway system infrastructure and are responsible for its safe and efficient operation.
Operators-Railways: Organizations that operate the railway system and are responsible for the safety of passengers and personnel.
Railway System Designers and Manufacturers: Organizations that design and manufacture the various components of the railway system, such as trains, tracks, signals, and control systems.
Regulatory Authorities: Organizations responsible for regulating the safety of railway systems and ensuring compliance with safety standards and regulations.
Contractors and Suppliers: Organizations that provide services and supplies for the construction, operation, and maintenance of railway systems.
Overall, Implementing this standard is mandatory in Europe for the management of the RAMS of railway systems. However, even organizations outside of Europe may choose to implement the standard to ensure the safe, reliable, and efficient operation of their railway systems. The standard provides a comprehensive and systematic approach to managing the RAMS of railway systems, which can help organizations reduce risk, improve safety, and increase performance.
