The change is due to https://github.com/eclipse/sumo/issues/5531
You have to possibilities for modelling this dual-track layout:

1) the way it is done in the original osm with two separate <way> elements
2) with a way that has attribute oneway="no" and that doesn't have the tag
railway:bidirectional=regular

I'm honestly not sure how oneway="no" with railway:bidirectional is
supposed to be interpreted.
To me the osm wiki implies that railway:bidirectional describes
capabilities of a single track.
On the other hand, oneway describes whether there are lanes in both
directions for regular ways.

A compromise could be to create two tracks that both can be used in either
direction (4 sumo edges) but this isn't implemented yet.

regards,
Jakob
