Preliminary studies

The method of study was defined by the Franco-Spanish summit of 2008. For its detailed description, refer to the page PROJECT of the site.


Study of freight traffic across Pyrenees

  • Study realized by Ineco / Setec International

This study was conducted over the period 2011-2013. The study focused on the updating of the Franco-Spanish traffic model, which analyzes the evolution of freight traffic between the Iberian Peninsula and the north of the Pyrenees for all modes of freight traffic (sea, rail, and road).

The study made it possible to estimate the freight traffic in the hypothesis of the realization of a new rail crossing of the Pyrenees in addition to the known projects of evolution of the French and Spanish transport infrastructures. Thanks to this study we have a predicted traffic forecast across the Pyrenees and the share that can be carried by rail mode by 2040, in different scenarios and with the elements of analysis on the carry-over of traffic induced by the project of both the road to the railway and the railway axes.

Study of environmental, technical and functional conditions

  • Study realized by Sener / Ingérop

This study was conducted over the period 2014-2015. The study made it possible to identify and prioritize the main environmental issues, sensitivities and risks in the broad sense (structure and characteristics of the territory, human environment, and transport networks), using a systemic methodological approach taking into account the results of the traffic study. It also takes into account two time horizons: 2030 and 2050.

The study makes it possible to have a presentation of the initial state in a large study area grouping the French and Spanish regions bordering the Pyrenees with the collection of data useful for highlighting places where to look for options of passage.

The hierarchy of the data allowed the clarification of the environmental stakes and the identification of couples of Spanish and French valleys that could provide opportunities for a new crossing of the Pyrenees.

Study of the territorial context

  • Study realized by Idom / Arcadis / Parmenion

This study was conducted over the period 2014-2015 with knowledge of the two previous studies used as a framework for framing the presentation speech of the project.

The study made it possible to identify the perception of the project by the institutional actors concerned by the project at local, regional, national and European level. Some 140 people were interviewed, which made it possible to feed the reflections on the functionalities and the stakes (economic, spatial planning, transport etc.) of the New Trans-Pyrenees High Railway Axis. The study allows to describe and analyze the social, political and economic context of the project by giving a vision of the questions raised by the project for the territory.

The study provides recommendations for the inclusion of a project for a new crossing in the territory and guidelines for the preparation of a public debate in France and prior consultations in Spain.

Study of corridors for possible routes

  • Study realized by Rail Concept / Eptisa / Anteagroup

This study took place during the year 2015.

The study of the possible corridors put in perspective the results of the three previous studies to identify the most favorable corridors of routes, considering also a wider field of problems: inscription in a European corridor, modalities for the realization of multi- Modality, economic conditions.

The study makes it possible to have proposals for possible path corridors validated from the point of view of civil engineering and railway techniques at the level of preliminary studies. Economic and socio-economic assessments are added to the environmental and technical elements in the comparison of possible route corridors.
