SNCF Réseau uses new application for real-time rail net monitoring

French rail infrastructure manager SNCF Réseau is using a new application for real-time track monitoring of its rail network in collaboration with technology company Capgemini. The tool called ‘New Generation Supervision’ is in use in some regions since July this year, and will be gradually deployed in all regions of France between 2021 and 2022. The tool will help to improve the regularity of traffic, but also passenger information.

The application is aimed at optimizing the supervision of the rail network in order to increase its performance and meet growing mobility needs. Thanks to this digital solution, the SNCF Réseau teams in charge of maintaining the 30,000 kilometers of lines are alerted in real time and mobilized by means of a mobile application which can precisely geolocate incidents.

The railway network is now remotely monitored and supervised to detect any technical failures in the tracks, says SNCF Réseau. This includes for example signalling, catenaries, level crossings or switches. Different systems work together to detect anomalies and warn maintenance staff, enabling installations to be quickly restored.

Optimising monitoring and maintenance

SNCF Réseau, in collaboration with Capgemini, initiated the overhaul of its supervision application. The result, called “New Generation Supervision” is an innovative application in service since July 1, 2020 in the Auvergne Rhône-Alpes region. This new tool will be progressively implemented in other regions between 2021 and 2022.

Thanks to the interactive application, incident management is more responsive and efficient and therefore contributes to improving the information provided to travelers, according to SNCF Réseau. In the event of contingencies, the application communicates the data in real time relating to the maintenance operation concerned, such as delivery times, arrival times on site, and response times. This information is instantly made available to rail operators, who can inform travelers.

Fully digital

With this tool, common to the four supervision centers across France, the goal is to build a vision of corrective and conditional maintenance needs on a national scale. It is capable of managing alerts from various sources. Ultimately, all the data from human monitoring, remote monitoring and monitoring trains will be sent back to the supervision centers where it will be collated and centralized. More broadly, the aim is to establish an extensive information system on the state of rail infrastructure and to assist in decision-making for appropriate maintenance.

The application enables SNCF Réseau agents to locate incidents on a dynamic map on which data relating to the infrastructure appears. They can identify the right contacts to perform maintenance depending on the route, time and specialty needed, such as electricity technicians or mechanics. Maintainers can be guided precisely to the place of intervention and communicate directly with the supervision center to exchange their findings and estimate the time it takes to resolve the incident. Digital intervention reports can be generate and managed  directly in the mobile application.


The “New Generation Supervision” application was co-built by SNCF Réseau teams and Capgemini project teams, and is an integral part of the SNCF Réseau digital transformation program called “Monitoring and Supervision”. Since the launch of this program in 2017, Capgemini employees have been designing and deploying end-to-end digital solutions, which rely on expertise in software engineering, supervision and hypervision, internet of things, digital transformation and mobility.The first tests of advanced processing of surveillance data on the  Lyon-Marseille axis have proved to be successful thanks to the use of software which carefully analyzes the history of breakdowns and the state of the installations to anticipate and carry out conditional maintenance before the incident.

“The deployment of New Generation Supervision, thanks to our partner Capgemini, will make it possible to improve not only the handling of incidents, and therefore the regularity of traffic, but also passenger information, says Olivier Bancel, Deputy Director General Production of SNCF Réseau. “Overall, we are going to move from very systematic maintenance to maintenance that is closer to needs, more precise and in real time: network maintenance at the right time and in the right place. It’s another step towards a high-performance network”.
