Following the Mandate of 13 February 2007 the Agency performed an analysis of the relationship between the 1435 mm and the 1520/1524 mm railway systems as far as technical and operational aspects are concerned, together with a strategic evaluation on the possibility of future convergence between the two systems (keeping apart the gauge differences). In this context the pertinence as well as technical and economical feasibility of a separate specific TSI valid for the 1520/1524 mm railway system was evaluated.
The conclusions of this analysis were reflected in the ERA recommendation to the Commission on 1520/1524 system.
Following this Recommendation, the Agency will include the 1520/1524 mm rail systems in the TSIs along with the 1435 mm and other track gauges.
One of the most important aspects of the EU 1520/1524 mm rail system is the high level of existing interoperability with third countries. In order to take full account of the specific constraints relating to rail links with third countries the Agency has established technical collaboration with the Organisation for Cooperation between Railways (OSJD) and set up a common working group (ERA-OSJD Contact Group). The contact group consists of experts from OSJD members (from both EU Member States and third countries) and ERA staff.
The output of the analysis of the existing specifications for the different subsystems of the 1520 mm rail system, which is being carried out by this group, will consist of seven separate reports, one for each subsystem. These documents will be a key input for the inclusion of the EU 1520 system in the TSIs.
The Contact Group has analysed the subsystems Infrastructure, Energy and Locomotives & Passenger Carriages. Locomotives part will be uploaded in ERA web during summer 2012. Analysis of other subsystems will be carried out in further years.
According to Article 3 of the Agency Regulation a Working Party consisting of sector representatives was established and has met at regular intervals for debriefing on the state of play of the subject.
