Based on an in-depth analysis of the individual elements of TTR and their requirements (in terms of IT needs, commercial conditions and legal framework), implementation packages were created, in which all required developments are bundled. Aiming for the full roll-out of TTR in December 2024, end dates were defined for all packages:

Implementation packages 1 and 2
focus on the division of roles and tasks under the new TTR process. In the course of these packages the TTR process description will be transparently published at national level, and all stakeholders made aware of the workflow.

Implementation package 3 covers the preparation of all framework conditions (including IT) needed for the smooth preparation of the capacity models and set-up of capacity partitioning.

In the course of implementation package 4, commercial conditions and allocation rules are commonly agreed and subsequently published in the Network Statements, the key documents for capacity applicants wishing to run services on European rail infrastructure. All legislation (European and national) concerning TTR should be adapted where needed.

Implementation package 5 covers all parts of the TTR IT landscape, which enables the process of capacity planning.

Finally, implementation package 6 will see to the implementation of all remaining IT micro services for the final TTR rollout. All legislation adapted under implementation package 4 must be fully applicable by this time.

Due to the large number of stakeholders involved in TTR, the actual start dates of the individual implementation packages will vary from stakeholder to stakeholder. National TTR implementation projects have started in late 2019, with all national stakeholders involved.
