Trains, planes and software-defined multilayer networks

Imagine you are in charge of your country’s public transportation. You have three divisions, busses, trains, and aeroplanes. Each division shares patterns of passenger traffic with each other, but otherwise operate independently. The population is generally satisfied with the level of service, even when switching between modes of transport, but you know that this is primarily due to the fact that your budgets have been generous enough to allow each division to build sufficient route capacity and frequency.
