Many destinations in Germany can be reached by train, tram or bus. Trains, undergrounds railways (U-Bahn), suburban railways (S-Bahn) and buses offer transport locally and regionally. Public transport within a city and the adjoining region is called "ÖPNV" (Öffentlicher Personennahverkehr).
If you use public transport regularly then special discounted tickets can be purchased from the local public transport company. Tickets with ten trips at reduced prices or monthly or yearly tickets can be purchased. Ticket issuing offices have information on the type of ticket best suited to you.
