Casablanca BW1, relationships

Is it normal to see 4 relations for BW1 ?

I could see only 2 relations and 2 ways (highway=busway) including the string “BW1” in ‘name’

Yes, the two relations are OK, half-ways: they are tagged as PTv2 (public_transport:version=2) and represent the 'aller' et 'retour' of the bus route. What’s missing: their ‘parent’ relation, the route_master relation.

Edit: add links to relations - Relation: ‪BW1 Salmia 2-Omar Al Khayam‬ (‪18041838‬) | OpenStreetMap and Relation: ‪BW1 Omar Al Khayam-Salmia 2‬ (‪18041839‬) | OpenStreetMap

Thanks ; I’ve added r18783086
