# Commission Decision of 30 May 2002 concerning the technical specification for interoperability relating to the rolling stock subsystem of the trans-European high-speed rail system referred to in Article 6(1) of Directive 96/48/EC (notified under document number C(2002) 1952) (Text with EEA relevance) (2002/735/EC), Division: Essential requirement 1.1.1:

Extent: E+W+S+N.I.

‘The design, construction or assembly, maintenance and monitoring of safety-critical components, and more particularly of the components involved in train movements must be such as to guarantee safety at the level corresponding to the aims laid down for the network, including those for specific degraded situations’.
This safety requirement is of universal application; as specified in Chapter 1, Section 1.3, this document is limited to the definition of those conditions relating to interoperability. In this regard, this essential requirement is satisfied when all the basic criteria that define the rolling stock in Chapter 4 of this TSI are met.
