All the innovations and tools developed by DGEX Solutions have one point in common: they were all created to satisfy the specific needs of major projects in the Paris Basin. The upgrading of the Gare de Lyons’ automatic signal box enabled the EIDA tool to be created to manage the production process of the south eastern European rolling stock depot, or Simu-site, to simplify the signalling tests for the new signal box. The Paris Montparnasse project transformed EIDA into a station/maintenance depot operational management tool: these are but a few examples!

The other point in common of these tools is that they are all – at varying levels – in an industrialization process: for OpenGOV, LeBonIT, EIDA etc. the challenges now are the connection with other databases, the installation on servers, and the exchange – via API (Application Program Interface) – with other IS tools.
Today, Simu-site is industrialized; Alstom is interested in OpenTCO becoming the reference tool capable of integrating information from older generation signal boxes for ATS+. The parameters are being defined for EIDA for ten or so maintenance depots, and it is running 24/7 at Montparnasse signal box to
manage communications with the Montrouge maintenance depot. LeBONIT is scheduled to be implemented at around fifteen sites before the end of this year, HERMES – which enables the creation of optimized trainset rosters – is being deployed with for SNCF Freight. These projects are successful due to the industrialization, the link with SNCF’s IS, and the coherence of data.

Designing resilient transport systems for our customers means that all the aspects of our organization have to be taken into account: e.g. a trainset roster and a track occupation diagram are closely linked. The organization of staff in a station depends on the track occupation diagram. The quality of the organization has a major impact on regularity and safety.
In addition to their instant advantages, the competency developed has to be
viewed on a long-term basis: ATS+, new traffic management tools, passenger
information systems, etc. and soon the integration AI. All of theese will enable
a new generation of engineers to be trained, who will be able to offer, develop
and design these future systems.
