A First Approach: UIC RailTopoModelFeasibility Study

Results / conclusions:95% of features in the topology models are compatible(similar iron network)Scalable core model is needed àpredefined (common) and user specific (personalised) extensionsTopology = model coreTopology model should support levels of detail (micro, meso, macro, corridor)The user decides which levels to fill


A First Approach: UIC RailTopoModelThe First Model

UIC RailTopoModel = generic railway data model designed to support current and future business usages and needsrailML® 3 = a common railway data exchange formatTogether, they form the ERIM proposal of a standardized data exchange format


Towards a new railML formatSchedule

Today: railML 2.2, in productive use by many railways in EuropeDevelopment Plan of the railML.org core team:

Development of railML 3 shall be based on the UIC RailTopoModel to ensure greatest compatibilityFirst Version will be railML 3.0 for special usecases (RINF), further development of railML 3.1 including users feedbackAim: all elements available in railML 2.2 infrastructureshall be contained in railML 3.1Further development of railML interlocking sub-schemato be included with railML 3.1In parallel: Collect ideas and extensions of railML 2.2 timetableand rolling stock for a railML 2.3 release next year(no infrastructure modifications expected)

UIC RailTopoModel & railML® ToolboxThe objective is to provide a complete standard set of tools based on railML exchange format, adapted to most business requirements

The global consistency is ensured by keystone: UIC RailTopoModel

Benefits of Open Standards + Open Source

Ø Ability to use other softwares (e.g. ESRI) as GIS client

Ø Already mature software

Ø Pay once, Run everywhere

Ø Ability to enhance code, or to fix bugs immediately

Ø Several GIS Open Source software editors in Europe
