Project data

Every project stores a few global settings that apply to the whole layout. You browse and edit them via Project settings (the gear icon in the toolbar).

Name

• Name — free text to identify your project

Scale

The geometric scale of the layout, among:

• HO — 1:87
• N — 1:160
• Z — 1:220

The scale is used:

• to set the default scale of newly created locomotives in the project,
• to filter the default track library.

You can change it at any time. A project can manage tracks and locomotives of multiple scales.

Length unit

Unit used to display distances (rail lengths, abscissas):

• mm (millimetres)
• inch
• m (metres)

Internal values are always in millimetres; this setting only affects display.

Speed unit

Unit used by the throttle and speed displays:

• Percent — percentage of the loco’s maximum speed. The most intuitive.
• KmH — kilometres per hour (real-world scaled, based on the project scale and loco calibration).
• MpH — miles per hour, same idea.
• SpeedSteps — display directly in mm/s, the physics engine’s native unit.

See Locomotive calibration (coming soon) to understand how speeds are computed.
