Knowledge domain Kennistrein

Our new knowledge domain: Kennistrein!

From January 1, 2026, we will switch to Kennistrein. From that moment, BraiNS will no longer be accessible. Kennistrein offers the same clear and user-friendly environment you’re used to, but it is still under development.

If you come across anything you miss, please let us know by sending an email to kennistrein@ns.nl or via the feedback button in Kennistrein. Kennistrein is already live.

Kennistrein vs. BraiNS: what changes and what stays the same?

• The design is different. Kennistrein aligns with NS’s corporate style.
• The search function is different. The navigation menu on the left side has disappeared. You can now only search via the search bar. This feature will be expanded and improved.
• The search function is not functional yet for English articles. You can use BraiNS until the 1st of January. In the beginning of January this will be fixed.
• All articles have been transferred 1 on 1 from BraiNS. The content remains unchanged.
• Logging in works differently. You’ll read more about this further down the page!
• Have you indicated that you want to keep your BraiNS account? Then you don’t need to request a new account for Kennistrein.
• Not all functionalities are working yet. Via Kennistrein in development you can see what is still coming and/or has already been reported.
