Open Point Notes
Braking aspects
It only applies to ERTMS/ETCS Baseline 2 (see Annex A, Table A2, Index 15).

Resolved for ERTMS/ETCS Baseline 3 (see Annex A, Table A 2, Indexes 4 and 13).

Index 28 – Reliability/availability requirements Frequent occurrences of degraded situations caused by failures of control-command and signalling equipment will decrease the system safety.
Minimum wheel diameter for speed greater than 350 km/h See Annex A, Table A 2, Index 77
Minimum axle distance for speed greater than 350 km/h See Annex A, Table A 2, Index 77
Metal and inductive components free space between wheels
See Annex A, Table A 2, Index 77

This is not an open point for freight wagons

Characteristics of sand applied to tracks See Annex A, Table A 2, Index 77
Vehicle metal mass See Annex A, Table A 2, Index 77
Combination of rolling stock characteristics influencing shunting impedance See Annex A, Table A 2, Index 77
Electromagnetic interferences (traction current) See Annex A, Table A 2, Index 77
Electromagnetic interferences (electromagnetic fields)
See Annex A, Table A 2, Index 77

This is not an open point for power systems other than DC

Vehicle Impedance See Annex A, Table A 2, Index 77
DC and low frequency components of traction current See Annex A, Table A 2, Index 77
Use of magnetic/eddy current brakes See Annex A, Table A 2, Index 77
Index 78 — Safety requirements for ETCS DMI functions This open point is related to the interface between ETCS on-board and the driver, i.e. errors in displaying information and in entering data and commands.
