RAMS
Reliability, Availability, Maintainability, Safety, Security – these important factors are combined in the short term RAMS. Enotrac is a competent and reliable partner in all of these areas. The experts have many years of experience covering a wide range of projects, from large, complex infrastructures (system safety and system integration) such as the Lötschberg (LBT), Gotthard (GBT) and Ceneri (CBT) base tunnels of the New Railway Link through the Alps (NRLA) to complete vehicles and small components such as speed sensors.
Enotrac’s expertise extends to both functional safety (SIL (Safety Integrity Leve), e.g. door control) and non-functional safety (e.g. fire protection). The identification of potential hazards in hazard workshops and the derivation of safety requirements and SIL are a big part of the experts’ tasks, as are verification and validation, safety planning and safety verification as well as approval planning and approval concepts. Last but not least, the area of cyber security is becoming increasingly important. Greater attention must be paid to the protection of infrastructures and vehicles, as there are more and more systems in railway technology that rely on wireless communication.
It’s about the big picture – it’s about system engineering!
System engineering is about the interaction of quality, and reliability, availability, maintainability (RAM) as well as safety and security within the railway system. This discipline is crucial for addressing various objectives:
- Ensuring the safety of people from hazards present in the railway system (safety). For example: the risk of barriers not closing when a train is approaching.
- Safeguarding the railway infrastructure from malicious threats posed by individuals, such as cyber-attacks.. Example: An example would be a hacking incident that could potentially bring the entire railway system to a standstill..
In addition, inadequate cybersecurity within the railway network would also impede the assurance of passengers safety.
Our approach to system engineering ” addresses these challenges. We are committed to ensuring that railway operations are not only reliable and highly available but also easily maintainable and secure from both a personal and cybersecurity standpoint.
This approach is central for the sustainable transportation of goods and passengers, achieved through our unique and innovative solutions.
Proven methods such as fault tree analysis, event tree analysis, Failure Mode Effects and Criticality Analysis (FMECA) are used. Enotrac is involved in standardisation committees and offers various training courses tailored to customers’ needs. Enotrac is also proud to collaborate with the Zurich University of Applied Sciences (ZHAW), contributing to the “Reliability, Availability, Maintainability and Safety” course in the Transportation Systems degree programme.
