Marseille Agency

Railways, Nuclear, IoT and Energy Management are the 4 main activities of the Marseille Agency.

Rail signalling, from analogue to digital technology

ERJI was founded in 1968 in Marseille by Jean Robert and began manufacturing electronic components for the SNCF. The R&D team is gradually expanding and is turning the corner on the digitisation of its relays by mastering in-house FDMS know-how and the very demanding CENELEC safety standards to reach the SIL 4 safety level (CENELEC standards EN50126, EN50128 and EN50129). It thus develops the BGS, a generic security database and obtains its SIL4 certification in 2016 by CERTIFER.

New railway signalling applications based on digital technologies were then developed: lateral wind detection, automatic switch-on, automatic pilot, etc.

A robust and reliable manufacturing process

The Marseille Agency controls the manufacturing process from start to finish:

The design office is specialized in Mechanics, CAD and CAD. He is able to make prototypes very quickly, thanks to modelling and the 3D printer;
Some components such as transformers are manufactured in Marseille according to historical know-how;
On site, the cards are soldered, wired and controlled, the equipment is integrated, tested, tropicalized and debugged.

Traditional but also "Agile" manufacturing processes

The manufacture of railway signalling relays and the design of new digital applications based on the generic safety platform SIL4 still require long-term V-cycle project management.

On the other hand, for IoT projects, all the teams in the BE, R&D and Production teams work using the Agile method: rapid prototyping (3D printers, CMS machine, CNC engraver, etc.), model development and test bench over a very short period of time, delivery of software updates at the high speed of the sprints, daily progress meetings. This makes it possible to be flexible and to meet the customer's needs as closely as possible, both in terms of deadlines and quality.

Nuclear power, a new critical area of activity in safety

In 50 years of experience in the sensitive and critical field of rail signalling, Agence Marseille has built a solid reputation as an expert in electronic systems related to operational safety and security. Since 2017, it has been diversifying and applying this valuable expertise in the field of component obsolescence management in nuclear power plants.

Member of FIF and the Digital Open Lab

In 2018, Agence Marseille became a member of the Fédération des Industriels du Ferroviaire and the SNCF Digital Open Lab. This allows it to be at the heart of SNCF's digital transformation and to develop its offer as closely as possible to the needs of its historical customer.

Key figures

Design office and industrialization

Open
  • A total workforce of 8 people 
  • Mechanical Software - 3D - Modeling
  • CAD/CAM software
  • Test bench and control software
  • 2 3D printers
  • 1 CNC engraver (rapid prototyping)
  • 1 SMD machine + reflow oven
  • 1 Milling machine
  • 1 Column drill

Production

Open
  • A total of 22 people trained according to IPC-A610, IPC-A620, IPC-7711 and IPC-7721 standards
  • 2 ovens
  • 1 climatic chamber
  • Selective wave machine
  • GD Electronics: all operators have a touch screen to use the manufacturing procedures that are digitized. The aim is to move towards "paperless" and to use only the latest versions of the procedures (the others are no longer accessible by operators).
  • Automatic test benches
  • 3 winding machines
  • 1 mechanical workshop (milling machine, column drill,...)
  • Various production tools (soldering irons, smoke extractors, manufacturing jigs, etc.)
  • 1 Varnishing booth

Research & Development

Open
  • A staff of 30 people
  • 4 business areas: Rail, Nuclear, IoT and Energy Management
  • A matrix organization based on 2 functional groups "Software Design" and "Hardware Design" and Project groups. In addition, there are various teams that are also cross-functional: BE, Industrialisation, FDMS (Reliability, Availability, Maintainability and Safety) and V&V (Verification and Validation).
