Working Groups

Currently the development of railML® is formed by four different active working groups; the Timetable Working Group, the Infrastructure Working Group, the Interlocking Developers Working Group and Ontology Working Group, which meet every four to eight weeks to exchange and discuss ideas and to identify needs.

(The rolling stock schema has been developed to a point where no further enhancements are currently necessary. Therefore no active working group exists for this subschema.)

The Infrastructure Working Group and the Interlocking Working Group have an international participant base from across the rail industry and are conducted in English. The Timetable Working Group primarily comprises members from German-speaking countries and communicates in German, although English-speaking participants are also encouraged to join.

Further information on the different subschemas can be found here.

If you are interested participating in one of our working groups and joining the railML community please do not hesitate to contact us.
