Same in Finland(Helsinki) as well. Its called the joker line, huge busses that go every 8-10 mins. Now theyre actually trying to replace it with a fast tram.
Similar in the Netherlands, plans for a tram line, turned out to be to expensive, got changed to bus line with dedicated lanes. Even though it was built to make an eventual transition to a tram easy, this seems to work better in hindsight than dedicated trams.
