RAM – Online training course
Welcome to this course on RAM — that’s Reliability, Availability, and Maintainability.
In many engineering contexts, especially in the rail and transportation sectors, RAM is typically presented as part of the broader RAMS discipline, which also includes Safety. While safety is of course crucial, it’s also a vast topic in its own right — one that often dominates the conversation in traditional RAMS training.
This course takes a different approach.
Here, we’ll focus exclusively on the RAM side of the equation.
Why? Because Reliability, Availability, and Maintainability are not just supporting roles to safety — they are critical pillars of system performance, customer satisfaction, and lifecycle cost optimization.
By isolating RAM from safety, we can dive deeper into the methods, metrics, and strategies that improve system uptime, reduce operational disruptions, and enhance long-term maintainability — all without getting overshadowed by safety requirements.
Course contents
This RAM-only (EN 50126) online training course covers the following aspects:
- What RAM is and why it matters
- The RAM lifecycle and its stakeholders
- Interrelation of RAM elements and introduction to Risk Reduction
- RAM documentation
- RAM tasks per lifecycle phase
- RAM parameters (MTTF, Inherent availability, Mean Down Time…) and practical exercises
- RAM techniques (RBDs, FTAs, FMEAs, etc.)
What is RAM in the context of EN 50126?
EN 50126 is a European standard that defines the requirements for the life cycle management of railway systems, focusing on safety, reliability, availability, maintainability, and safety (RAMS). It provides a structured approach to managing RAM (and safety) throughout the entire railway project lifecycle, from design to operation and decommissioning.
RAM terms are defined below:
1️⃣ Reliability
- Probability that the system performs its required functions under stated conditions for a specified period of time.
- In simple terms: How often does the system fail?
- In ETCS context: reliability ensures the onboard and trackside signalling components operate correctly without frequent faults.
2️⃣ Availability
- The degree to which a system is operational and accessible when required for use.
- Depends on both Reliability and Maintainability.
- In railway terms: Is the signalling system ready and operational when trains need to run?
3️⃣ Maintainability
- The ability to restore a system to operational state after a fault, within a defined time, using defined resources.
- In other words: How quickly and easily can you repair it?
- Critical for railway operators to minimize downtime after failures.
Prerequisites
There are no prerequisites for taking this course. Engineering studies and/or railway experience is an advantage.
Reading the EN 50126 part 1 before taking the course is also recommended.
Target Audience
This course has been designed for anyone involved in RAM-related activities in railway projects. For example, this course is useful for Railways project managers, system engineers, hardware engineers, RAMS managers, designeres, testers, integrators, verifiers, validators, etc.
Course Duration
This RAM course has an approximate duration of 1h30.
