The MVV is the Munich city public transport system.
"MVV" stands for "Münchner Verkehrs Verein" which literally translates to "Munich transport union". It is a union because the U-Bahn, S-Bahn, buses, and trams all operate under one unified ticketing system. This means that although the U-Bahn and S-Bahn are run by separate companies, they have an agreement such that an S-Bahn ticket is valid for the U-Bahn, and vice-versa.
The MVV website is at: www.mvv-muenchen.de/en
All the information you'll ever need is to be found on the above website. This includes:
- ticket options
- route maps
- U-Bahn (subway trains)
- S-Bahn (city trains)
- Strassenbahn (trams)
There shouldn't ever be any need to ask an MVV ticket or timetable related question on TT because all info is on the official MVV website already. So go read that site first!
