Division 7.2.3 IMPLEMENTATION: ROLLING STOCK (ON-BOARD EQUIPMENT)

Rolling stock specially built or upgraded (re-signalled) for high speed shall be equipped with class A interfaces for use on the trans-European high-speed network and shall ensure that the on-board functions, interfaces and minimum performance required by this TSI are included according to the routes concerned as described in Annex C.

Rolling stock equipment providing class A interfaces shall be able to accommodate additional modules providing class B interfaces (STMs) as may be required by the awarding authority.

Rolling stock equipped with only class B systems shall be considered acceptable for use on interoperable lines equipped with class B interfaces when it fulfils the requirements of the control-command subsystem described in this TSI. The existing class B control-command equipment may remain in use during its life cycle.

When running on a line which is equipped with both class A and class B systems, the class B systems may act as fallback arrangement for the class A system if the train is equipped with both class A and class B systems.

Class B control-command equipment on-board shall not interfere with other TSI subsystems nor with the other equipment installed upon the infrastructure of the European high-speed network.

Class B control-command equipment on-board shall not be susceptible to emissions from other TSI subsystems.
