In-Depth Information
Up to now the TSI are related to the Trans European Network. With
the new Interoperability Directive it is foreseen to widen the scope.
Due to this it has to be decided whether new systems, i. E. new
category of Rolling Stock and Lines need to be considered.
Safety can only be achieved, if all relevant risks can be handled by
specific measures and as long as we have no common European Rail-
way Infrastructure the Network specific aspects play an important
role.
Cross Acceptance of Authorizations that are offered by the National
Safety Authorities is one major element of the new “Interoperability
Directive” of the European Union. Those requirements, that are not
yet harmonized in TSI have to be classified against the national re-
quirements of other Member States in A (cross - accepted), B and
C (not cross accepted) - parameters. The result need to be fixed in
a cross reference document which includes all relevant parameters as
a basis for future international Rolling Stock projects. It is possible
that this process in the future lead to harmonized requirements on a
European level but it is nevertheless an important intermediate step
because it leads to "harmonization" on bi- and multilateral levels.
Safety includes technical and process - oriented aspects. Beyond the
authorization for placing into service by the responsible National
Safety Authority, the Railway Undertakings (RU) and Infrastruc-
ture Manager (IM) are obliged by the European Safety Directive to
implement a Safety Management System (SMS) based on common
requirements, which include, among others, processes with which the
RU and IM ensure that they control all risks of railway operation,
including purchase of new material. In order to fulfill this RU and
IM have for example for the concrete network access to check, that
the specific Rolling Stock is compatible with the Infrastructure on
which it is foreseen to be operated. Hereby the RU and IM identify
for example the necessary Control Command and Signalling System.
Only with this second step a safe integration can be ensured.
The European Common Safety Methods (CSM) on Risk evaluation
and assessment, which have to be applied since 19.07.2010 according
to a European Regulation enforce the sector to follow a structured
process which include especially the identification and classification
of possible hazards. The CSM also regulate the selection of one of the
three known risk acceptance principles: Code of Practice, Reference
SystemorExplicitRiskAnalysisandbasedontheresultsthedecision
aboutthenecessarysafetymeasurestoproofthatallpossibleHazards
are controlled. The result has to be documented in a hazard log and
assessed by an independent safety assessor. The CSM also foresees
a permanent Hazard Management. With the implementation of this
transparent and structured process cross acceptance of subsystems
like for example Rolling Stock shall be supported. Everybody speaks
“the same language”; a code of practice is for example identified in
the same manner in all EU - Member States.
