The landscape of railway software development is undergoing a shift with the arrival of EN50716:2023, the latest standard for ensuring safety-critical software in railway applications. But what does this mean for the well-established EN50128? Let's delve into the world of railway standards and explore this exciting development.

Why are Railway Software Standards Important?

Imagine a bustling railway network. Trains whizz by, carrying passengers and cargo safely to their destinations. Behind the scenes, complex software plays a vital role, controlling everything from signaling systems to onboard operations. Any glitches in this software can have catastrophic consequences.

Railway software standards like EN50128 and the new EN50716 provide a robust framework for developing safe and reliable software. These standards define a rigorous development lifecycle, from requirements gathering to testing and maintenance. By adhering to these standards, developers ensure their software meets the highest safety integrity levels (SIL) required for different railway applications.

EN50128 vs. EN50716: A Streamlined Approach

EN50128 has been the go-to standard for railway software development for over a decade. However, the industry has evolved, demanding a more comprehensive and adaptable approach. EN50716 addresses this need by:

• Unifying Standards: EN50716 supersedes both EN50128 and EN50657 (previously used for specific SIL levels). This simplifies the landscape and ensures consistent application across the board.
• Expanded Scope: EN50716 applies to a wider range of software, including basic integrity levels (formerly SIL0). This broader reach strengthens overall railway safety.
• Improved Clarity: The new standard streamlines terminology and clarifies specific requirements, like those for application data.

The Future of Railway Software Safety

EN50716 is not just an update; it's a significant step forward. By adopting this standard, the railway industry can benefit from:

• Enhanced Safety: The unified and comprehensive approach reduces the risk of software-related incidents.
• Increased Efficiency: Streamlined processes and broader applicability ensure smoother development workflows.
• Future-Proofing: The standard is designed to accommodate future advancements in railway technology.

So, yes, EN50716 is replacing EN50128. But it's not a complete overhaul. The new standard builds upon the strong foundation laid by its predecessor, offering a more robust and adaptable framework for ensuring the safety of our railway systems.
