Unofficial GTFS Realtime feed for Hamburg🔗

This endpoint provides realtime transit data for Hamburg in the GTFS Realtime (GTFS-RT) format.

Underneath, it works by polling the HVV HAFAS endpoint underneath. Those interested in delays of all vehicles, instead of a particular one, don't have to poll HVV's API brute-force: They're able to fetch the data efficiently from here.

Note: This feed is run by people not related to HVV and the government.

Why use this API?🔗

• Realtime Data – This API returns realtime data whenever the underlying API for HVV's mobile app provides it.
• No API Key – You can just use the API without authentication.
• CORS – This API has CORS enabled, so you can query it from any webpage.
• Caching-friendly – This API sends ETag & Date headers, allowing clients to cache responses properly.

Getting Started🔗

Note: This project is work-in-progress, the feed might go offline at any time! I'm happy to receive any kind of feedback via the hamburg-gtfs-rt-server GitHub Issues.

The URL of the GTFS-RT feed is https://v0.hamburg-gtfs-rt.transport.rest/feed.

As an example, let's use print-gtfs-rt-cli and jq to inspect it:

curl 'https://v0.hamburg-gtfs-rt.transport.rest/feed' -s | print-gtfs-rt --json | head -n 1 | jq
