Summary of the discussion results in the Rail transport subpanel

• Our recommendations for the User Requirements

Document

• Our perceived R&D needs
• Answers to the strategic questions asked from us

Agenda

2

• Requirements are defined as qualitative as a starting point, and

several ongoing projects (ex. STARS, X2RAIL2) will contribute to refine the requirements in the near future to reflect real user needs for the specific operational scenarios

• Distinction among user, functional and system safety

requirements should be kept

• Requirements specified by the user community should also

reflect economical effects, which affect potential GNSS implementation

Highlights of our recommendations for the User Requirements document

3

Applications:

• Continue ongoing effort in the area of virtual balise +
• dometry + cold movement detector in frame of ERTMS
• Start to focus on ATO + ERTMS Level 3
• Add predictable maintenance and survey

3 3 mai ain ch challe llenges:

• Safety and availability according to CENELEC and user needs
• Interoperable solution based on GNSS
• Cost effective solution
