Division 2.2.2 PrinciplesF1

This TSI covers those elements (as set out in Chapter 4) of the rail ‘ operation and traffic management ’ subsystem, where principally there are operational interfaces between RU and IM and where there is a particular benefit to interoperability.

RU and IM must ensure that all requirements concerning rules and procedures as well as documentation are met by the establishment of the appropriate processes. The set up of these processes is a relevant part of RU’s and IM’s safety management system (hereinafter referred to as ‘SMS’) as required by Directive 2004/49/EC ^f1 . The SMS itself is assessed by the relevant national safety authority (hereinafter referred to as ‘NSA’) before granting safety certificate/authorisation.
