The reason to use separate ways for trams can be seen in the other tram tracks I mapped:
http://www.openstreetmap.org/#map=18/50.83181/4.33280 You can clearly see that very often the rails don't follow the asphalt where the cars drive. Cars can make 90 degree turns, the tram rails need to follow smoother curves. So it's only in situations where buses follow the tram bedding: http://www.openstreetmap.org/#map=19/50.82432/4.33561 that one can have common ways for the tram and that service road. * For normal streets we draw 2 ways for the tracks and 1 for the asphalt road. * For dual carriageways we draw 2 ways for the tracks and 2 for each side + sometimes a service way between the tracks, when the buses use it too. It's rather exceptional that the service road and the tram rails can use the same OSM way. Keep in mind it's only a model to represent reality. A model which uses lines for what in reality are areas, so whatever we do, it will never be a perfect fit. I'm sure André won't agree with me, but to implement the solution he proposes, we'd have to restart OSM from scratch. And even though it may simplify and solve some things, it would make other stuff a lot harder.
