Who is the client?
A global railway technology company specialising in advanced signalling, measurement and digital rail solutions. Its technologies support railway operators worldwide, with more than 2,500 signalling and measurement systems in service, over 500,000 km of railway infrastructure inspected every day, and solutions used across 90% of the global high-speed rail measurement train market. As part of its growth strategy, the company is developing a next-generation digital interlocking platform for the German railway market. To accelerate development while maintaining the highest standards of safety and engineering quality, it sought a trusted engineering partner to support this transformation.
What was the problem?
Modern railway programmes generate enormous volumes of engineering knowledge.
Customer requirements, standards, design documentation, engineering rules and technical specifications are spread across thousands of documents that engineers must analyse, understand and continually reference throughout development.
For the customer, this has created several challenges:
- managing thousands of Deutsche Bahn signalling requirements;
- accelerating requirements engineering without compromising quality;
- reducing dependency on a limited number of signalling specialists;
- enabling multidisciplinary teams to access engineering knowledge quickly;
- ensuring secure handling of sensitive customer information.
Rather than introducing isolated AI tools, the objective has been to embed AI directly into engineering activities where it can create measurable value.
What was the Expleo solution?
Expleo has supported the customer throughout the early systems engineering phases of its digital interlocking programme. Working alongside the customer’s engineering teams, Expleo has helped transform thousands of Deutsche Bahn requirements into structured, traceable engineering specifications, providing the foundation for system architecture, software development and future verification activities. To achieve this, Expleo has combined expertise across:
- Systems Engineering
- Requirements Engineering
- Digital Signalling
- Railway Systems Architecture
- AI-enabled Engineering
Rather than treating AI as a standalone solution, Expleo has embedded it into these engineering activities through its secure enterprise AI platform, accelerating knowledge-intensive tasks while maintaining full traceability, safety and governance.
As software delivery accelerates and AI becomes embedded in business-critical processes, organisations need to improve quality without slowing innovation. Expleo helps organisations deliver faster, reduce risk and build trust in AI, ensuring that systems are designed to perform reliably at scale.
Examples of solutions we deploy and deliver:
- AI-native quality engineering
- Responsible AI assurance
- Intelligent test automation
Legacy technology, fragmented data and manual processes often prevent organisations from realising the value of AI. Expleo helps organisations modernise applications, turn manual workflows into intelligent processes, and build the data and AI foundations required to scale innovation.
Examples of solutions we deploy and deliver:
- Intelligent automation
- Data engineering
- Legacy modernisation
Many organisations know where AI could create value but lack the strategy, governance and operating model needed to scale it. Expleo helps turn AI ambition into an enterprise-wide capability by defining the strategy, establishing the governance and building the foundations for successful AI adoption.
Examples of solutions we deploy and deliver:
- Digital, data & AI strategy
- AI risk, ethics & governance
- AI operating models & readiness
How did that help?
By embedding AI directly into everyday engineering activities, Expleo has transformed how engineering teams interact with project knowledge. Instead of spending time searching through documentation or relying on a limited number of experts, engineers can access relevant information instantly, validate requirements earlier and collaborate more efficiently across international teams. AI acts as an engineering accelerator, allowing specialists to focus on high-value design decisions while routine, knowledge-intensive tasks are automated.
What were the results?
The AI-enabled engineering approach has delivered tangible benefits across the project:
- Up to 50% reduction in requirements review effort through AI-assisted validation.
- Faster access to project knowledge and technical documentation.
- Reduced dependency on scarce signalling specialists.
- Improved consistency and quality of systems engineering activities.
- More efficient collaboration between German and international engineering teams.
- A stronger engineering foundation for the development of next-generation digital interlocking systems.
Beyond the project itself, the initiative has demonstrated how AI can be deployed securely within safety-critical engineering environments while delivering measurable operational improvements.
Could it work for me?
Engineering organisations across transportation, aerospace, automotive, defence and industrial manufacturing face similar challenges: increasing system complexity, growing volumes of requirements, scarce specialist expertise and pressure to deliver programmes faster without compromising quality. Expleo’s AI-enabled engineering approach is designed to address these challenges by embedding secure, governed AI capabilities throughout the engineering lifecycle. Rather than offering isolated AI tools, Expleo helps organisations industrialise AI across systems engineering, from requirements management and knowledge retrieval to engineering automation and multilingual collaboration, allowing teams to deliver complex programmes more efficiently while maintaining the standards expected in regulated industries.
