[Tagging] Tram tracks running in a road

Hi Luca,

Thank you for letting me know. That was indeed an oversight. I fixed it by
removing the tags from the little highway part, then combining that way
with the railway=tram. There are no bus lines that are passing that part,
so it's enough to have it as railway tram. It took many hours to
incorporate those tracks, even though we have them as open data from UrbIS.
They have the rails though and we want to combine those rails into tracks.

If you want to see high resolution imagery for Brussels, the
AGIV(laanderen) is available in JOSM's list of WMS sources.

Jo
