| 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.” |
