Dear all,

the electrification model in railML 3.2 is rather heterogeneous: there are aspects in Common (CO), Infrastructure (IS) and Rollingstock (RS) schema. A detailed analysis can be found in the Gitlab issue #511 [1].

With railML 3.3 we want to harmonize the electrification model. A possible solution is also described in [1]. In detail:
* Move TractionMode from CO to RS.
* Remove ElectrificationSystem as base for TractionMode and add an electrificationSystemRef.
* Add an attribute to ElectrificationSystem specifying the type of electrical interface between the infrastructure and rolling stock to replace IS:electrificationSection@contactLineType and parts of RS:engine/powerMode/@mode and RS:trainEngine/tractionMode/@mode.
* Deprecate IS:electrificationSection@contactLineType.
* Replace "electricOverheadLine" and "electricThirdRail" with one common value in TractionMode/@mode
* Should we add more properties to RS to match the requirements specified in IS, or is there no demand for this?
* Clean up subelements of IS:electrificationSection (see #512 [2])

Any further feedback on this from the community is highly appreciated.
