The best part is that it's about as complicated as the Adelaide Metro trainmap.
The most complicated it gets is at Goodwood, Keswick and Mile End. 3 sequential stations that lie on 2 lines each and serve as the only real interchange stations, which is useless because Goodwood is the 3rd stop from the city. Other than that interchanges are just splitoff lines.
Including Genesis and Exodus we have a more complex transport system than my city. It's also probably more efficient!
I finally explored the Ma'Spa trainworks today and I'm really impressed. That underwater tunnel was brilliant.
