On-station and on-train passenger information systems (PIS and CIS) sit at the intersection of customer experience and operations. Yet across fleets and networks, obsolescence is often treated as an inevitability, with the only option offered by original manufacturers being a full system replacement. Increasingly, this response is being questioned; according to the International Union of Railways (UIC), rail technologies must now be designed with “future-proofing” in mind, precisely because of these long lifecycles.
Unlike other forms of technology, railway systems are not designed for rapid replacement. Rolling stock and infrastructure often operate over 30+ year lifecycles, while information systems evolve in cycles as short as 5–10 years, and passenger expectations even shorter. These three elements are tightly interconnected, yet evolve on very different timelines.
KeTech cannot influence the age of rolling stock or on-station equipment, or the pace of change in passenger expectations. However, we can design systems that evolve alongside them, or redesign existing systems to extend their life while upgrading capability, functionality and performance to meet current operator and passenger needs.
Trapped Between Spares and System Replacements
This is becoming increasingly difficult to ignore as operators manage ageing fleets and wayside equipment alongside growing expectations for real-time, data-driven passenger information. Many networks are investing heavily in digital programmes aimed at improving the quality, consistency and responsiveness of passenger information, often within the constraints of legacy onboard and station systems that were never designed for today’s levels of connectivity or integration.
When original equipment manufacturers (OEMs) shift their focus to next-generation technologies, legacy support quickly diminishes. Train operators are usually presented with two options: sourcing hard-to-find and expensive spare parts to patch the problem, or a costly full system replacement.
For operators managing complex networks, demanding operating environments and strict accessibility requirements, neither option is ideal.
A Different Approach
KeTech offers a third, more sustainable and cost-effective solution. We do not treat obsolescence as a trigger for replacement. We treat it as an opportunity for collaboration and engagement, to work out the most cost-effective, optimal design.
Our approach is built around targeted re-design, extending the life of existing systems while upgrading capability where it is actually needed.
This is delivered through a wrap-and-embrace model, where existing systems are assessed at component level, functional infrastructure is retained, and only obsolete elements are replaced. New capability is then integrated around the existing architecture rather than imposed through system-wide substitution.
This is enabled through form-fit-function engineering, where physical compatibility, system integration and functional performance are preserved while obsolete components are replaced with modern equivalents. It allows systems to be upgraded regardless of original supplier or age.
As the rail industry and governments continue to emphasise sustainability and reduced emissions, the concept of extending the life of existing assets has never been more relevant.
Unlocking Digital Capability
Crucially, this is not just a replacement; it is an upgrade. By combining KeTech’s expertise in both hardware and software engineering, we integrate these disciplines to deliver what we term a “better than new” solution.
KeTech’s hardware-software integration capability enables features, such as real-time information, that were previously impossible on older systems. Operators can connect and centralise disparate legacy systems, allowing on-station and on-train information provision to be managed from the same single operator interface.
Layered Upgrades
Rail operators around the world are moving towards real-time data, predictive disruption messaging, multi-modal integration and more dynamic passenger information systems. These capabilities do not necessarily require full system replacement, but rather intelligent layers that can sit on existing infrastructure.
By upgrading these layers rather than rebuilding entire systems, operators can deliver modern passenger experiences while extending the life of critical assets and reducing unnecessary cost and operational disruption.
The reality is that rail networks are not failing because systems are old. They are being challenged because systems evolve at different speeds within the same operational environment.
At KeTech, our approach is simple.
Obsolescence does not have to mean replacement.
It can mean extension, enhancement and intelligent modernisation.
And in a rail environment defined by long asset lifecycles, rising passenger expectations, increasing system complexity and restricted budgets, that distinction matters more than ever.
