Overview

Transport for Switzerland (opentransportdata.swiss) is the official Swiss open data platform for public transport, offering timetables, real-time data, and GTFS feeds. It covers trains, buses, trams, and boats operated by Swiss transit companies. An API key is required and can be obtained by registering for a free account on the platform.

💡

Beginner Tip

Start by registering at opentransportdata.swiss to get your API key — the GTFS static feed is easiest to begin with for timetable data. Use the Journey Planning API for real-time trip routing.
