Local-Only Transport Stations (obsolete)
The original functionality of this mod (local train stations) was added to the game in the Mass Transit update! You will only need this mod for local passenger harbours and airports
Adds a checkbox to passenger harbours and airports to make them only accept local traffic (no cruise ships and planes from other cities).
You can create local cruise ship lines & air lines with the Ship Line Tool and Airplane Line Tool
Compatibility & Performance
Compatible with:
- Advanced Vehicle Options
- Improved Public Transport
- Airplane Line Tool
- Ship Line Tool
You can disable the mod at any time (local stations even remain local without the mod).
Planned Features
- Limit outside trains to a certain outside connection (e.g "only trains from northern connection allowed here")
- Configure which outside trains arrive at which platform (multi-track stations)
