Real-time locations of Helsinki Region Transport (HSL) public transport vehicles.

The realtime data comes from the Digitransit HSL MQTT API, which is a "work in progress", "very likely to change in the near future" and "there might be mysterious bugs lurking in the data". At least some of the tram numbers are wrong, so if you use trams, you might want to check them all on the filters page.

The line filter page in Helsinki Transit Live lists all HSL lines, but realtime data is actually available only for an unknown part of them. New HSL ticket and information systems (to be updated late 2016?) will improve both the coverage and the update frequency of realtime data. See the web interface for a look at the current coverage.
