The main challenges facing the rail sector are how to modernise infrastructure and rolling stock, simplify services and integrate technological innovations to remain an attractive proposition.

Le ferroviaire ou comment concevoir la mobilité autrement

Digitising networks and trains for greater efficiency

To become more competitive, the sector needs to increase the number of trains and organise the interoperability of its systems for international transport, while digitising its traffic management systems. Improving passenger comfort, connectivity and safety will also attract new clients.

There has been a resurgence of interest in rail. Already an inexpensive and green mode of transport, it is undergoing its own digital transformation.

Pierre Zembri, Director of the City, Mobility and Transport Laboratory, shares his analysis.

Flux des réseaux ferroviaires

Fault identification tool for safety facilities. This solution helps traffic operators quickly find alternatives to keep traffic flowing.

ATS pour les métros

We deployed a service centre (work for around twenty engineers, 50% of whom work on our own premises at different periods) for validating operational scenarios for automated metro projects (ATS Lille, Amsterdam, Mexico City, Santiago, Malaga, etc.) for major players in the sector.

Tester les équipements ferroviaires pour plus de sécurité

Scalian specified changes for projects in relation to the existing test bench. We adapted and integrated developments made to other benches in Germany, in order to make the bench more generic. We were also involved in design and implementation of changes, integration and validation of the bench, and maintenance.

Suivre des processus qualité à tous les stades de production

We provided support for project management and ensured the correct application of processes according to ALSTOM procedures and V-models. The aim of PrQSM is to identify difficulties, ensure that action plans are well defined and followed, and pass on information to line management using problem-solving methods (Ishikawa, 5 Whys, 8 Disciplines).

Analyse de risques pour homologuer les équipements

Production of a project risk analysis file for the approval of the Riyadh metro. Scalian conducted the security risk analysis based on the EBIOS (Expression of Needs and Identification of Security Objectives) 2010 method, ran security sessions (interviews, workshops), conducted the architecture review of the industrial and operational IS, drafted security measures and carried out a residual risk analysis.

Savoir conduire les grands projets pour faciliter la mobilité

We created and supervised the project management control unit liaising directly with the PL14 project management team. PL14 (extension of metro line 14) is the flagship infrastructure project that will facilitate mobility for the Paris 2024 Olympic Games.

Garantir la sécurité à bord

With ATB, the train collects electrical signals from track-side devices and then the system overrides the driver’s controls in two cases:
– failure to reduce speed at a warning signal: the ATB slows the train sufficiently to stop at the next signal;
– violation of the speed limit: the ATB immediately initiates emergency braking.
Scalian deployed V&V activities for the SIL4 system, hardware and software, by managing and coordinating a global outsourced testing team (SW, HW, functional and non-regression testing).
