3.ESSENTIAL REQUIREMENTSU.K.
3.1. Compliance with the essential requirements U.K.
According to Article 4(1) of Directive 2008/57/EC (1), the Trans-European Rail System, subsystems and their interoperability constituents must meet the essential requirements set out in general terms in Annex III of that Directive.
In the scope of the present TSI, the fulfilment of relevant essential requirements listed in Chapter 3 will be ensured for the subsystem by the compliance with the specifications described in Chapter 4: Characterisation of the subsystem.
3.2. Essential requirements aspects U.K.
The essential requirements concern:
Safety,
Reliability and Availability,
Health,
Environmental protection,
Technical compatibility.
According to Directive 2008/57/EC (1), the essential requirements may be generally applicable to the whole Trans-European Rail System or be specific to each subsystem and its constituents.
3.3. Aspects relating to general requirements U.K.
The relevance of the general requirements to the Telematics Applications Subsystem for Freight is determined as follows:
3.3.1. Safety U.K.
The essential requirements 1.1.1, 1.1.2, 1.1.3, 1.1.4 and 1.1.5 of Annex III to Directive 2008/57/EC (1) are not relevant to the Telematics Applications subsystem.
3.3.2. Reliability and availability U.K.
‘The monitoring and maintenance of fixed or movable components that are involved in train movements must be organised, carried out and quantified in such a manner as to maintain their operation under the intended conditions.’
This essential requirement is met by the following chapters:
Chapter 4.2.10: The Main Reference Data,
Chapter 4.2.11: Various Reference Files and Databases,
Chapter 4.2.12: Networking & Communication.
3.3.3. Health U.K.
The essential requirements 1.3.1 and 1.3.2 of Annex III to Directive 2008/57/EC (1) are not relevant to the Telematics Applications subsystem.
3.3.4. Environmental protection U.K.
The essential requirements 1.4.1, 1.4.2, 1.4.3, 1.4.4 and 1.4.5 of Annex III to Directive 2008/57/EC (1) are not relevant to the Telematics Applications subsystem.
3.3.5. Technical compatibility U.K.
The essential requirement 1.5 of Annex III to Directive 2008/57/EC (1) is not relevant to the Telematics Applications subsystem.
3.4. Aspects relating specifically to the Telematics Applications Subsystem for Freight U.K.
3.4.1. Technical compatibility U.K.
Essential requirement 2.7.1 of Annex III to Directive 2008/57/EC (1):
‘The essential requirements for Telematics Applications guarantee a minimum quality of service for passengers and carriers of goods, particularly in terms of technical compatibility.
Steps must be taken to ensure:
that the databases, software and data communication protocols are developed in a manner allowing maximum data interchange between different applications and operators, excluding confidential commercial data,
easy access to the information for users.’
This essential requirement is specially met by the following chapters:
Chapter 4.2.10: The Main Reference Data,
Chapter 4.2.11: Various Reference Files and Databases,
Chapter 4.2.12: Networking & Communication.
3.4.2. Reliability and availability U.K.
Essential requirement 2.7.2 of Annex III to Directive 2008/57/EC (1):
‘The methods of use, management, updating and maintenance of these databases, software and data communication protocols must guarantee the efficiency of these systems and the quality of the service.’
This requirement is specially met by the following chapters:
Chapter 4.2.10: The Main Reference Data,
Chapter 4.2.11: Various Reference Files and Databases,
Chapter 4.2.12: Networking & Communication.
This essential requirement, especially the method of use to guarantee the efficiency of these Telematics applications and the quality of the service, is the foundations for the complete TSI and not restricted to the Chapters 4.2.10, 4.2.11 and 4.2.12.
3.4.3. Health U.K.
Essential requirement 2.7.3 of Annex III to Directive 2008/57/EC (1):
‘The interfaces between these systems and users must comply with the minimum rules on ergonomics and health protection.’
This TSI does not specify any additional requirements to existing national and European rules related to minimum rules on ergonomics and health protection of an interface between these Telematics applications and users.
3.4.4. Safety U.K.
Essential requirement 2.7.4 of Annex III to Directive 2008/57/EC (1):
‘Suitable levels of integrity and dependability must be provided for the storage or transmission of safety-related information.’
This requirement is met by the following chapters:
Chapter 4.2.10: The Main Reference Data,
Chapter 4.2.11: Various Reference Files and Databases,
Chapter 4.2.12: Networking & Communication.
