ERIM-Project: Publication of the UIC Railway Topology Model

  • Infrastructure

In 2013 the “UIC ERIM feasibility study” was conducted in order to analyse and propose a project plan to build a universal infrastructure data exchange format, and a common “language” to improve the railway data exchange. Based on this “UIC ERIM feasibility study”, the ERIM workgroup developed the “UIC RailTopoModel”, which could be the basis for a common exchange language (railML 3).The first version of the documentation of this UIC RailTopoModel can be found on, to be discussed by the railML-community and the railway sector.

After a successful year in 2013, the project is continuing in 2014, starting with the “RADAMO-IT and ERIM 2014 Kick-off meeting” which took place on 16 January 2014 at UIC Paris. It was a great opportunity for all participants (BLS, DB, ERA, Infrabel, JBV, ÖBB, Prorail, RFF, VR) to share the current results and launch the work for 2014: the UIC RailTopoModel was reviewed; moreover the current railML work and proposed project roadmap for 2014 and 2015 were presented to the audience.

As committed in September 2013, the next UIC RailTopoModel and RINF conference will take place on 8 April 2014 at UIC Paris, open to all railway stakeholders. During this conference the final version of the UIC RailTopoModel will be presented. Sample national data will be displayed graphically using the UIC RailTopoModel. Moreover a first application to infrastructure data for RINF using railML will be shown. Further information and mandatory registration is possible via
