Hi @kevin_schnippkoweit@wouter.bulens72EDZ , 

 

Indeed, IFC will exchange the geometry of each sleeper or any other rail object, with the metadata included, if you map it to the good class :slightly_smiling_face:

Its each object geometry that's being exchanged, you can add the technical reference for the sleepers in the ¨Pset_TrackElementTypeSleeper" if you need to make reference to a national standard, reference geometry.

 

Hope it helps
