Unofficial GTFS Realtime feed for Hamburg

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

API status

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?

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

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