The TTR or Timetabling Redesign project aims to harmonize between Infrastructure Managers the schedules for capacity design and information publication.

The expected benefit is better capacity coordination between Infrastructure Managers and better access to information for customers and partners, especially for international needs.
This page provides access to the data produced by SNCF Réseau as part of TTR.
Information on TTR deliverables is available in the French Network Statement in Article 4.9.

The TTR deliverables

Here are the main deliverables:

The Capacity Strategy: It describes new or deposited lines, major structuring projects and projected volumes at the border. A draft version is made in June of Y-4 (X-42) for a final publication in December of Y-4 (X-36) (X = M-12, beginning of Annual Service).

The Capacity Model: It reviews volumes by market, on the structuring lines of the National Network. The objective, in target, is to be able to implement a model that will be integrated into a tool called European Capacity Management Tool (ECMT) with a draft version in March of Y-2 (X-21) and a final publication in June of Y-2 (X-18).

Capacity Supply: It consists of all the pre-built train paths and the main works, on the entire RFN. In a graphical form, the SIPH tool, in Consultation mode, provides access to this data. A "toolbox" supports this approach: a guide explaining the modalities of authorization and access to SIPH consultation as well as a training document on this tool. This can be supplemented by a view per file.

Temporary capacity restrictions (TCR): This data is shared, over several annual services, in the format required by the RNE IS (TCR Tool). A first implementation in this tool takes place at the end of Y-3, with the structuring projects (TCR major & high). A second implementation takes place at the end of Y-2, with the updated major & high windows as well as the medium and low importance windows (TCR medium & minor).
