Railways have information, but …Railways have information, but …
Data can be ambiguous as it is defined according to specific needs, with no check of consistency with other definitions
Data is in proprietary formats and require specific interpretation
Data is available in local databases, not easy to access to Interfaces are built on demand, based on specific
requirements Interfacing and data processing costs are high Data is consumed by specific applications and is normally
not available for wider usage Data hides useful information which is not easy to extract
and is often wasted Information systems cannot be easily upgraded
ScenarioScenario
The number of Actors in Railways is growing due to market opening
EC and ERA aim at achieving interoperability within the European railway network
There is an increasing need for information exchange in the Railways, between all involved Actors, e.g. to fulfil TSIs (regulations) or to improve efficiency
Means to handle the complexity of the railway system and ensure consistency of information are needed

Task Force on Telematic Applications in Rail
Task Force mandateTask Force mandate
Part A: to identify possible needs for telematics applications which will allow stakeholders to source the data necessary to discharge their legal obligations under the Interoperability and Safety Directives, but which are not yet covered by works and systems already mandated by existing EU legislation.
Part B: assist the Commission in launching further activities which involve putting in place business and governance structures for the development and maintenance of telematics applications identified under part A.

The InteGRail approachThe InteGRail approach
Main characteristics: Flexibility – to adapt to any kind of existing system
No need to change legacy systems
Modularity –selected information only will be made available directly from the source
No need to copy information to a central database
Non-ambiguity – ensure that information is consistent Automatic check of consistency
Scalability – the grid can grow as needed New actors can be added at any time

IEC TC9 WG22: Train Communication Network
Scope and resultsa)to define a complete network for digital communication onboard trains b)Developed in strong cooperation with UICc)Finally resulted in standard documents IEC 61375-1 (TCN) and IEC 61375-2 (Conformance Test)d)UIC issued several leaflets to define the communication data UIC556, UIC557, UIC647
e)Several European Projects contributed:

Vision on the futureVision on the future
Describe data accurately regardless of its native format Create a virtual data exchange layer on top of the current assets
and systems Avoid any risks associated with configuration changes or updates Allow easy data retrieve according to User (man or machine)
needs Facilitate service reuse reducing application development cost Improve interoperability at train, consist, vehicle, subsystem level Simplify cross-country, cross-system, cross-operator interaction Create added-value from existing information Inject innovation in the railway system , improving its performance Pave the way for a data transfer standard within the Rail domain

ConclusionsConclusions
The enlarging amount of information exchange needed for efficient, interoperable and competitive operation of railways bring to the need of a common language in order to remove bottlenecks and avoid future problems
InteGRail solution was conceived, designed and developed in order to cope with such kind of problems
New standards are in preparation in order to support the future solutions
All this will contribute to turn the Vision into reality
