Hi! Those bus route names are explicitly chosen to be descriptive. The 'name' field of the bus route should follow a specific format and is not the official name of the bus route. That comes from the guidance at https://wiki.openstreetmap.org/wiki/Buses

The actual route name is already stored in gtfs:route_long_name which gets automatically updated from Winnipeg Transit's own data every 3 months. The route number is stored in gtfs:route_id

The idea behind that guideline was to make route relations discernible whenever an editor or a changeset page on osm.org displays a list of relations. For this one feature type only, we're supposed to use the name tag to describe the feature. Apps don't actually use the `name` field on bus routes.
