Caching

Disruptions are cached per station code for 5 minutes. This balances freshness (disruptions can appear and resolve quickly) with avoiding rate-limit issues on the NS API.

Notes

NS uses Dutch type names (storing, werkzaamheid); the API maps these to disruption and maintenance for consistent English output.
The impact field contains NS traveller advice — typically a detour suggestion. It is populated only when NS has issued formal advice for a disruption phase.
