- With its global efficiency, first of all in the domain of network infrastructure
A major key success factor to this challenge will come from our capacity to
master the digital railway system, and force usage of digital standards.

Network Infrastructure
A major improvement to efficiency, in both projects and maintenance activities, will come from our capacity to organize collaboration between contributors, and their solutions.

Standardization in Railways

4. Railway System is complex and involves numerous technologies
Digitalisation of Network Infrastructure will requires miscellaneous digital standards
- some coming from other industries,
- some specific… to be designed.
Railway industry benefits from the experience of more advanced industries, and will work to the alignment of its specific digital standards

5. Standardization in Railways
3 major projects leaded by European Infrastructure Managers (IMs) are currently addressing standardization for Digital Continuity
Within bSI, China BIM Alliance signed an agreement with 6 European IMs to design the future digital model for design and construction in railway
IFC Rail
The RailTopoModel project, leaded by UIC (Union Internationale des Chemins de fer), involve 12 IMs to design the digital model for railway operation
EULYNX Consortium brings together 12 IMs in the design of digital standardization for railway signaling
IMs involved in multiple projects are working to the alignment of the 3 standards

6. Standardization in Railways
Those 3 projects for digital standardization will globally
cover most of the Railway Infrastructure life cycle…
On January 2018, they decided to work for their alignment,
… based on OGC standard for geography and geometry (linear territorial assets)
One example of business case showing the need for integration of standards
Project : increase by 20% the density of traffic between 2 cities
Scenario of topology, routes and traffic are simulated using RTM, and finely designed using Eulynx
Design and construction phases require both IFC Rail and Eulynx
Operation involve both RTM (traffic management) and Eulynx (Control Command)
Maintenance require all of them (functional properties, 3D, technical compatibility,…)

13. Digital Twin - next steps
Simulation and Optimization, from Design to Operation
Going from early design to operation is a long process, involving numerous actors, internal and external.
BIM and Digital Twin will develop digital continuity on the infrastructure description: shared information/data
Simulation will become unavoidable to secure and validate each component and the whole operational system at each step
