Track Planner
Planning a Pit Lane
Plan a Pit Lane as a branch off your track, and understand which technical capabilities depend on it.
What is a Pit Lane?
A Pit Lane is a branch in your track geometry that lets vehicles leave the main route and rejoin it again.
In a few steps
- Plan your main route first.
- Add a Pit Lane branch using compatible track parts.
- Make sure the pit route reconnects correctly to the main route.
- If fueling is required, include a PSAU (Pit Stop Adapter Unit).
- Check the resulting technical capabilities.
Tip
Not every Pit Lane needs a PSAU — it's only needed if fueling is required.
Pit Lane geometry and fueling capability are separate things
A Control Unit alone already enables fuel consumption. Fueling and Pit Rules additionally require a PSAU: Control Unit + PSAU.
Pace Car
Pace Car capability requires a Control Unit plus a second Pit Lane, or a Pace-Car Lane.

Community publication (Digital 132 / Digital 124)
For Carrera Digital 132 or Carrera Digital 124, if a PSAU is present it must be reachable from every physical lane — that's a requirement for Community publication.
Physical reachability matters
Whether a PSAU is reachable follows from the track's physical topology, not from how it looks arranged in the layout.
Note
Not every Pit Lane needs to include a PSAU — only when fueling is intended.
Pit Lane as a branch in physical topology
A Pit Lane is a branch in the track's physical topology, not just a visual element in the layout.
Reachability is based on physical paths
Whether a PSAU is reachable from every lane is determined from the track's physical paths.
Visual left/right is not the source of topology truth
Physical connectivity has to be determined from the actual track structure, not from the visual arrangement in the editor.
Technical boundary
The exact switching and lane-entry mechanics of individual Pit Lane parts are intentionally not part of this knowledge base.
