Build your first working passenger line

What to do

1. Pause and choose two useful locations in one town. Place passenger stops whose catchment covers residential buildings and a destination. Check the passenger-access highlight and street path; nearby buildings behind an inaccessible entrance do not establish access.
2. Build a road depot connected to the road carrying those stops. Keep this first test small. Avoid buying a large fleet or building an expensive railway before you know the stops form a usable service.
3. Open Line Manager, select New Line and add both stops in travel order. Inspect the displayed path. A line cycles back to its first stop, so check the return path as well as the outward trip.
4. Select the line and use Buy Vehicles, or open the connected depot. Buy a passenger vehicle, not a cargo truck, and assign it to this line. If buying through the line is unavailable, inspect depot access and vehicle compatibility.
5. Resume and follow the vehicle through both stops. Inspect boardings, waiting passengers and the completed journey. Add capacity only when the actual queues and occupancy justify it; a new empty trip is not a reason to duplicate the fleet immediately.

How to tell it worked

The vehicle leaves its depot, reaches both stops and carries passengers on a usable trip. Then review the line balance over several complete trips before expanding. A valid route preview alone does not demonstrate demand or profit.

If you are still stuck

No passengers: recheck catchment and the paths to useful destinations. No depot access: trace the continuous road connection. Vehicle assigned to the wrong line: inspect its line field. Once it runs, use the linked satisfaction and profit checks instead of rebuilding the whole town.
