Graou: Redefining French train travel

For numerous commuters travelling in France, delays have become an all too familiar part of their daily routine. However, amidst the frustration and uncertainty, one individual has emerged with a groundbreaking solution: Graou, a real-time map of the French railway network.

Join us as we dive into the story of Graou and explore how it has revolutionized train travel, particularly for those navigating the challenging Metz to Luxembourg route.

Unveiling Graou

Nicolas Wurtz, a passionate train enthusiast and computer lover, developed Graou in 2014 with a single goal in mind—to enhance the lives of commuters. Graou, short for "Gestion des Roulants Assistée par Ordinateur" serves as a centralized web app that provides invaluable real-time information, streamlining the daily experiences of those relying on this often delayed route.

Enhancing the Commuter Experience

Graou is more than just a scheduling tool; it is a game-changer for commuters. By offering access to up-to-date schedules, potential delays, traffic forecasts, and even local recommendations, Graou equips travellers with the essential information they need to navigate the challenges of their daily line. Additionally, the app facilitates easy sharing of schedules with loved ones, creating a sense of reassurance and improved work-life balance.

Elevating Contextual Awareness

Wurtz's vision for Graou extends beyond providing schedule assistance; it focuses on enhancing the overall commuter experience. By integrating real-time train arrivals, tracking intersections, and identifying line crossovers, Graou empowers travellers with contextual awareness and enables them to make informed decisions during their journeys. Since its launch, Graou has gained significant popularity, with thousands of users benefiting from its features on a daily basis.

Real-Time Mapping for All

While Graou primarily serves the needs of commuters, Wurtz has also considered the general public. He has developed a real-time map of the French railway network that is accessible to all. Leveraging Open Street Map's open data initiatives and harnessing relevant datasets from SNCF Réseaux, Wurtz has created an interactive map that displays theoretical schedules, delays, cancellations, and their impacts over time. This tool proves invaluable in assisting travellers with planning their journeys and mitigating the challenges posed by delays.

A Personal Touch

Knowing many French commuters, especially on the Metz to Luxembourg line, I can attest to the significance of Graou in transforming their travel experience. The app has provided them with real-time updates, allowing them to adjust their schedule accordingly and make more informed decisions. It has alleviated the frustration and uncertainty associated with delays, enabling them to navigate this challenging route with greater ease and peace of mind.


Graou has become a beacon of hope for commuters navigating in France, offering real-time updates, enhanced convenience, and invaluable support in the face of delays. Nicolas Wurtz's passion for trains and his dedication to crafting a user-friendly application have redefined the way we approach train travel in this region. As we continue to rely on Graou's real-time map and its comprehensive features, we are not only better equipped to navigate our journeys but also empowered to reclaim control over our commuting experiences. With Graou by our side, delays may persist, but our ability to overcome them confidently and efficiently has never been easier.
