The Nullhaven Transit Authority operates buses, marked road links, ordinary platforms, and selected lower transit routes beneath the city.
Network
The authority connects the Press District, Eyeview School District, Moon Garden Ward, and the Aero Reservoir Zone. Routes are named by signal color and transmission number because compass directions are unreliable in parts of the city.
Travel documents
Local trips require only a resident pass. A Void passport is checked when a vehicle crosses the final city signal or enters an interspace route such as Starlight Highway.
Service changes
Static rain, upward wind, and black-sun warnings can reorder stops without moving the tracks. Printed station boards remain the official route record whenever electronic displays disagree.
