Different scales of movement use different layers of infrastructure.
The working Station plan does not rely on one universal vehicle. Ordinary inhabited regions use metro-like systems for city and intercity movement. Much longer journeys have been associated with dedicated high-speed corridors: rocket-sled and pneumatic-tube concepts were both explored as ways to exploit the Station's enormous linear scale without forcing surface settlements to accommodate extreme-speed traffic.
These names describe developed transport roles more confidently than final hardware. Metro-scale regional transit is comparatively stable; rocket sled versus pneumatic implementation remains a working design space rather than a locked canonical technology.
The outer circumference supports a distinct transport regime.
Discussion developed "sonic tram" and zero-gravity ferry concepts for routes associated with the outer Station and low-gravity/static superstructure. These are not simply faster surface trains: they belong to a different reference-frame and access environment from the rotating inhabited rim. Their exact propulsion and docking systems remain unresolved.
Crossing the Station means crossing moving boundaries.
Transport between countries, sectors and structural layers may encounter slip interfaces where adjacent Station systems do not share the same motion. The working plan therefore includes transfer through slip-ring/interface structures rather than assuming every route is a continuous rigid track.
Vertical movement through rotating and static layers has been discussed as a timed operation through aligned slits or openings. The crossing is consequently an infrastructure event: access depends on relative geometry and timing, with interlocks and safe waiting regions implied even though their detailed mechanism has not yet been designed.
Loss of normal transit should not make an interface absolutely impassable.
An emergency ladder/manual crossing concept was developed for at least some vertical interfaces, with usable alignment windows discussed on the order of ten minutes. The figure is provisional and should not be treated as a universal Station period; its value is architectural: a failed powered crossing may still have a slow, hazardous, timing-dependent human route.
Transport can fragment while habitation persists.
The distributed hierarchy permits local network loss without implying failure of the Station itself. A metro closure isolates settlements locally; loss of a long-distance corridor increases journey time or separates regions; failure of a reference-frame interface can make an otherwise nearby destination inaccessible. This supports the wider Station model in which communities may remain viable while becoming operationally isolated.
Conversely, transport systems depend strongly on structural alignment. Ring displacement, fused interfaces, geological subsidence or loss of timing/control machinery may sever routes before the surrounding habitat becomes uninhabitable. Transport degradation is therefore an important early expression of structural decline.
Transit is constrained by geometry, rotation and settlement geography.
Global journey scale derives from 600.20:10; reference-frame crossings from 600.20:20; structural interfaces from 600.20:30; geological movement from 600.20:40; and the destination hierarchy ultimately couples to habitation under 600.20:80. Maintenance access and degraded-route behaviour also overlap 600.20:90.
This record preserves the present transport model, not its chronology.
The conversations in which metros, long-distance sled/tube systems, outer trams/ferries, slip interfaces and timed vertical crossings emerged belong in 400 Development Records. Real transport, maglev, evacuated-tube and rotating-interface sources belong in 700. Fictional comparisons belong in 750. Tribunal timetables, route maps or operating notices represented as in-universe artefacts belong in 100.
