RAMS Analyses

Proper Safety Analysis for Reliable and Safe Rail Engineering

The number of requirements specified for reliability and safety of European rail engineering is constantly rising. Accreditation bodies are increasingly asking for detailed proof of quality, for example, RAMS (Reliability, Availability, Maintainability, Safety) analysis for products and services. Our experts can carry out RAMS analyses of your rail system for you. We inspect your technology and company based on international norms, allowing you to get ahead of the competition.

Benefits at a Glance

With an assessment of your safety management system and RAMS analyses from TÜV Rheinland you can:

  • Fulfill the required European safety and quality standards for rail engineering
  • Get comprehensive, industry standard guidelines for the design of your safety systems
  • Gain cost-effective and efficient solution suggestions for electronics, software, mechanical, hydraulic, and other components and for partial systems
  • Benefit from our broad experience in the implementation of hazard prevention measures
  • Take advantage of RAMS inspection results in many fields of application besides rail engineering using a concentrated collection of the right know-how and appropriate software tools

Our Services for Safety and Quality of Railway Technology

For certification procedures, our experts offer a multitude of services designed to help you fulfill safety and quality standards. These include:

  • Assessment and issuing of analyses and reports
  • Evaluation and optimization of the system security architecture
  • Consequence Tree Analysis

  • Fault Tree Analysis (FTA)
  • Hazard Log
  • HAZOP (Hazard Operability Study)
  • Interface Hazard Analysis (Zonal Analysis)
  • Preliminary Hazard Analysis (PHA)
  • Safety evidence in compliance with DIN EN 50126, DIN EN 50128, and DIN EN 50129 norms
  • Subsystem Hazard Analysis, meaning the analysis of potential hazards of subsystems
  • Secure information transmission processes such as DIN EN 50159
  • Maintainability Analyses

Advantages of RAMS Analyses

RAMS (Reliability, Availability, Maintainability, Safety) analyses are increasingly important – and required – for homologation procedures. Based on earlier forms of rail engineering, there was only one initial safety requirement – that a component was either relevant for safety or not. No secondary safety inspection would be carried out. However, today, according to CENELEC standards, the European Committee for Electrotechnical Norms standards rail systems are inspected on the basis of RAMS analyses based on compliance with the definable safety steps: SIL for short - Safety Integrity Level. This demands a high level of technical system knowledge, coupled with experience in the field of statistic and probability theory analysis.

Possible Fields of Application for RAMS Analyses

  • Rail engineering: conventional wheel and track systems, automatic driverless systems, maglev technology, train guiding systems, signaling systems
  • Aerospace technology: audit systems for airplane components
  • Nucleonics
  • Control technology
  • Electrical supply networks
  • Street vehicles
  • Telematics, for example, toll collection systems
  • Military technology
