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.
On track to the future!
Fault identification tool for safety facilities. This solution helps traffic operators quickly find alternatives to keep traffic flowing.
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.
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.
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).
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.
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.
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).
