text: Agreed - the line name is "Main North" - One of the services that run on it is called  "Newcastle & Central Coast Line"
  
  I think we need to have separate relations for lines and services.  i.e. : relations for:
  1) "Main North" railway line
  2) "Newcastle" railway line
  3) "Newcastle & Central Coast Line" service
  4) "Hunter Line" service
  5) Perhaps other services?
