The urbanisation is mindboggling. People live in huge skyscrapers that grow around large railroad hubs. They combine business, market and living districts. The majority of population is between the hammer and the anvil, that being railroad tycoons and farmers. Some people die without ever stepping outside.
Roads to these cities are mostly used by villagers who choose sturdy and easy to repair vehicles. They are filthy rich, nonetheless, without them big cities would descend into disorder and rule of the strongest within days.
Railroad is the fastest way of travelling, but an incredibly costly one - maintenance and greed taking their toll. There is a railroad lobby that assures monopoly by campaigning about the dangers of oxidane or thwarting development of flying machines behind the scenes. And inability to make even a single good landing strip isn't helping it to grow beyond small agricultural aviation.
