On the 3rd of December 2014 the second timetable developer meeting was hosted by the railML partner iRFP in Dresden. A total of 10 developers of 8 different railML partners discussed the following topics:

• Certification process for railML®
• State of development for infrastructure / UIC RailTopoModel
• Timetable development requirements in railML 2.3
• Roadmap Timetable in railML 3.0

For the railML subscheme infrastructure a use case based approach was selected. This approach, which was introduced by the infrastructure scheme coordinator Christian Rahmig, aims to document and to analyse the requirements for an adjustment to the UIC RailTopoModel. The timetable development will use similar processes in terms of railML 3.0. Therefore railML users are provided with an increased level of transparency about the supported use cases of a software of an interface. Furthermore potential model changes for a successful refactoring in railML version 3.0 were discussed.

The Timetable Developer Meeting Spring 2015 will take place in March 2015 in Vienna. The results of the meeting will be presented on the 27th railML conference. (Author: Philip Wobst, Hacon Hanover)
