FAQ

Is Model Railway Calculator suitable for modelers in the US?
Currently, Model Railway Calculator is designed for European NEM-standards and uses metric measurements. Users in the US report that the lack of imperial unit support makes the app difficult to use for their specific projects.
Does Model Railway Calculator support N or 00 gauges?
Reviewers note that the app is currently limited in its support for specific model gauges like N or 00, which prevents hobbyists from using it for certain projects.
Are there alternatives to Model Railway Calculator?
Users seeking imperial unit support or broader gauge coverage often look for alternative reference charts or calculators, as Model Railway Calculator is currently metric-only.
