Minimum reliability/availability requirements shall be specified in order to limit the decrease of the system safety due to the frequent occurrence of degraded situations.

Safety requirements

Safety requirements for ETCS DMI functions for the set of specifications No 1 in Table A2 of the Annex A to the CCS TSI laid down in Decision 2012/88/EU.

Ergonomic aspects of DMI

Ergonomic DMI requirements for the set of specifications No 1 in Table A2 of the Annex A to the CCS TSI laid down in Decision 2012/88/EU.

Interface with service brake

Interface requirements with the service brake for the set of specifications No 1 in Table A2 of the Annex A to the CCS TSI laid down in Decision 2012/88/EU.

Other ETCS requirements (related to existing not interoperable networks)

ETCS requirements related to pre-B2 on-board equipment, compatibility with existing lines where pre-B2 equipment is installed. Or ETCS optional functionalities that may have an impact on the safe movement of the train.

Specification of condition of use where ETCS on-board does not implement all functions, interfaces and performances

Analysis of the impact when not implementing all functions, performances and interfaces specified in CCS TSI by the ETCS on-board subsystem. Useful for additional authorisations.


Specific operational requirements



Specific items to place on-board

To announce specific items to place on-board which are required for operational reasons in normal and degraded mode (e.g. scotches, if the parking brake performance is not sufficient depending on track gradient, coupling adapters, rescue couplers, etc.). Requirements for distribution and availability of the items may be added here. See also parameter 9.5.3.


Ferry transport

Requirements concerning the use of ferries by the vehicle, including running gear and vehicle gauge constraints, requirements for securing and fixing.


Freight-related items

Freight-specific requirements.


Design, operation and maintenance constraints for the transport of dangerous goods

E.g. requirements derived from RID, national rules or other regulations for the transport of dangerous goods; including facilities specifically required for dangerous goods.


Specific facilities for the transport of freight

E.g. securing of freight, air-supply for other purpose than brake, provisions for the hydraulic/pneumatic equipment of freight wagons, requirements for freight loading and unloading, special requirements to the vehicle for vehicle turn dumping.


Doors and loading facilities

Requirements concerning freight loading doors and hatches, their closing and locking.
