Tractie is the design system for NS (Nederlandse Spoorwegen), the Dutch national railway operator, built specifically for internal employee-facing applications rather than the public-facing NS travel app.
It's strongest as a rarer example of a design system built explicitly for internal operational tools at a large transit operator, useful reference for teams building internal staff/operations software rather than consumer-facing products.
Designers building internal or operational tools (not customer-facing apps) who want to see how a large transit organization structures an employee-facing system.
Documentation is scoped to internal NS use, so treat it as a structural and process reference rather than a public component kit to install.
NS Dutch Railways' official design system, aligning design and code.
