Overview

Transport for Sweden (Trafiklab) is a developer platform providing access to public transport data across all of Sweden. It offers real-time departures, trip planning, and historical data from operators like SL (Stockholm) and Skanetrafiken. OAuth authentication is required, so you will need to register for a free developer account at trafiklab.se.
