I think you are putting the servant before the master here.  The public 
transport schema is there to model the world; I feel that you want the 
world to fit the schema.

I don't think you should go beyond fast and slow trains in subdividing.

I'm also a bit concerned as to where the data is coming from.  This 
feels like it might be an undeclared bulk import, possibly using data 
without appropriate licenses.
