Provider data
PNR, live running and reservation-dependent results are requested server-side from an approved provider. The browser never receives the provider key.
Calculations and estimates
Date, berth and connection tools apply documented rules or transparent heuristics. Every estimate is labelled and should be rechecked when the underlying rule can change.
Confidence labels
Provider data means it came from the connected feed. Planning estimate means it was calculated. Official link means the final decision belongs on the linked railway service. Not available means we do not know.
