Scenes or Timelines - what to prefer

I'm about to create an interactive map for cross country paths/tracks. A map as background and perhaps 30 tracks, each one animated when user pushes a the actual button.
First attempt was to create one scene and add a timeline for each track. To organize and to help scaling I put a track and the corresponding button in the same group.
Second thought – should I go for scenes, one for each track?
I would be glad for some advice how to go along.
