So with the focus on transport, how is that portrayed in your fiction if you are building your own world? Whether it is fantasy or science fiction you write, your characters will need some way of getting around so is what you have thought of inferior or superior to what we have here on Earth?
Who is your world's equivalent of the great pioneers of transport - Brunel, Stephenson etc? If you've established that whatever form of transport you use (and almost inevitably there will be several), how efficiently does it run? What are the downsides?
Where does the energy come from to power it? And if you use magic as a kind of fuel here, just how much of the stuff does your world need as I imagine it would take a colossial amount. There would be a price to pay for that somewhere and that in itself could be a fascinating story.
