The train network here in Perth has been represented in a similar style. The ferries have been added in as well as the bus that goes to the airport to try and make our system look more impressive. It just seems to emphasise how limited our trains are! So much scope for improvement.
I am looking forward to the day we get more train lines, and maybe light rail, and I could have a local map worthy of my wall!
PS I commute to work by bus. So I do use public tranpsort!!
