Timetables (schedules), locations of stops, and real-time location information of all municipally run or commissioned transit services (buses, subway, rail, tram, etc). (More info)
The data's content quality is excellent. Every bus, route and stop as well as real time tracking are freely available on their site.
The data's structure at the moment leaves much to be desired (you'd pretty much have to scrape the pages or sniff the mobile apps to discover their api's) but according the the app page there is a public api being built.
