Official Nederlandse Spoorwegen (NS) Train Data API

Overview

The Transport for The Netherlands (NS) API provides access to official Dutch train data, including real-time timetables, journey planning, station details, and disruption updates. Key endpoints include /ns-api-stations (station list), /ns-api-avt (arrivals/departures), and /ns-api-treinplanner (route planning). Responses are in XML format.
