None of Wedderburn Junction, Irrewarra or Lubeck.
We are looking for a station from which a (theoretical) Melbourne-bound train could travel to the big smoke via multiple routes, without a change of direction.
No location can be passed through more than once.
This location is, or was, a junction.
If travelling from Melbourne, a train reached this station with an electric staff. Beyond, on either of the lines, the driver would have a train staff (or ticket).
The location is no longer a junction, and indeed is, to the best of my knowledge, no longer an "official" location. But trains still trundle past...
This station shares its name with a famous (or perhaps infamous) Australian singer.
