It's simple to get around in Dortmund, with tickets valid for all bus, train,
underground and tram lines. There are three fare zones (zones A, B and C), but you'll only need a zone A ticket for travel in the centre.
If you're travelling three stops or less, save money with a Kurzestrecke (short journey) ticket.
Kurzestrecke - 1.10 (Euro)
Zone A ticket - 2 (Euro)
Zone B ticket - 3.70 (Euro)
Zone C ticket - 8 (Euro)
