Here is my next interation of a diagram showing railway, metro, light rail and key connecting bus and ferry services around Sydney, Australia.  Many of the lines shown are under construction, planning, or are just my own ideas of what would be useful additions to this growing network.

The framework of this diagram is largely complete but there is a lot more work to be done before this is finished.  However, I may not get around to completing this project for sometime, so I thought I'd share the diagram in its current state for feedback and suggestions.
