Pioneering rail safety and innovation: an interview with Yapy Merkezi iDiS Engineering's RAMS chief

Güray Kera, RAMS chief at Yapı Merkezi İDİS Engineering, discusses the company’s award-winning approach to innovation and safety in railway technology, the challenges of adapting global standards to local needs, and the strategic vision driving the transformation of rail systems in Turkey and beyond.

Metrolink is a recipient of three awards in the 2025 Railway Technology Excellence Awards.

Güray Kera: Thank you. These awards are a proud milestone for us. They affirm our unwavering commitment to engineering excellence, safety, and innovation. At Yapy Merkezi iDiS Engineering, our core value – to produce the most beneficial value for humanity with the least social cost – is embedded in everything we do.

These recognitions validate not just our technical achievements, but also our deep-rooted responsibility to contribute to safer and smarter rail systems for the communities we serve.

At the same time, we are currently piloting a major fare restructure that simplifies our pricing system. By making fares easier to understand and more predictable, we are removing barriers that have historically made transit harder to use. This clarity and simplicity also promotes equity, ensuring that more riders, from students to working families, can benefit from a system that works for them.

Together, these initiatives demonstrate that our broader mission is not just about running trains. It’s about delivering a more equitable, sustainable, and connected future for everyone in our region.

GK: Our vision is to be a global benchmark in smart and safe railway technologies. Our mission is to design and implement cutting-edge, reliable, needs-driven solutions that elevate transportation standards. We aim to lead the transformation of rail infrastructure through technological innovation, while always prioritising safety, sustainability, and customer needs.

GK: Urban rail environments demand exceptional precision, safety, and reliability. We recognised a growing need for a train protection system that was both locally relevant and globally aligned. Our motivation was to fill that gap with a solution that integrates the best of international standards while addressing the unique operational realities of urban networks in developing markets of Turkey.

GK: We engaged in active dialogue with national operators and local authorities. Through field studies, stakeholder consultations, and data-driven analysis, we tailored our solutions to meet Turkey’s specific capacity, interoperability, and safety requirements. Our adaptive development process ensured alignment with both national strategies and global best practices.

GK: We carefully studied systems like PZB, LZB and ETCS to extract proven functional approaches. However, local signalling environments, topographical challenges, and operational frameworks required customisation. Our key considerations included compatibility with existing infrastructure and rolling stock, ease of maintenance, and compliance with Turkish technical specifications and international safety norms.

GK: Compliance with standards like IEC 62290 and achieving Safety Integrity Level 4 (SIL 4) are non-negotiable benchmarks in our development process. They ensure our systems are not only interoperable and future-proof but also adhere to the highest levels of safety and reliability. These standards are essential to gaining the trust of international stakeholders and ensuring our solutions are globally deployable.

GK: Our solutions feature fail-safe mechanisms and real-time diagnostics—all designed to prevent incidents before they occur. What truly sets us apart is our deep integration of local operational insights with state-of-the-art automation, enabling precise control and rapid response in dynamic urban settings.

GK: We follow a modular design approach for both hardware and software, allowing us to adopt and scale our systems based on operators’ specific requirements and budgets. Our platforms are divided into hardware modules based on wayside equipment and software-configurable, ensuring long-term adaptability. This approach ensures an optimal balance between performance, affordability, and ease of implementation.

GK: One of the key challenges was developing a system that meets the highest safety integrity requirements while remaining fully adaptable to current rolling stock, which is in use across various networks. Additionally, ensuring full compliance with both international and local standards added layers of testing and validation that demanded precision and patience. 

We overcame these challenges through strictly applying the general life cycle process defined in EN 50126, while ensuring close coordination between our hardware design and application engineering teams. Early prototyping, rigorous testing, and a culture that supports learning from setbacks were critical in helping us refine our solutions effectively and deliver a robust, applicable system. 

GK: We nurture a collaborative, learning-driven culture. Our engineers are encouraged to experiment, challenge norms, and take calculated risks. Regular training, internal innovation workshops, and partnerships with academia ensure our teams remain at the forefront of technological advancement and industry trends.

GK: We are focused on further enhancing our signalling systems, expanding our portfolio with various rail systems for urban, national, or international networks, and deepening our digital integration capabilities. We are advancing drone-based monitoring solutions to enable proactive, early-warning alerts across railway networks. Strategically, we aim to contribute to the realisation of fully autonomous, smart rail networks that can adapt to evolving mobility demands.

GK: We see ourselves as both a contributor and a catalyst. In Turkey, we are committed to helping shape a modern, resilient rail ecosystem. Internationally, we are expanding our partnerships to share our expertise in adapting global systems for local success. Our aim is to bridge innovation gaps and enable accessible, safe, and intelligent rail systems globally.

GK: We deeply appreciate the trust and collaboration of our partners and clients. These achievements are not just ours; they reflect a shared commitment to safer, smarter, and more sustainable transport. We look forward to continuing this journey together and invite all stakeholders to join us in shaping the future of mobility.
