supervised by the Munich Transport and Tariff Association (M�nchner Verkehrs- und Tarifverbund GmbH). The Munich tramway is the oldest existing public transportation system in the city, which has been in operation since 1876. Munich also has an extensive network of bus lines.
The extensive network of subway and tram lines assist and complement pedestrian movement in the city centre. The 700m-long Kaufinger Strasse, which starts near the Main train station, forms a pedestrian east-west spine that traverses almost the entire centre. Similarly, Weinstrasse leads off northwards to the Hofgarten. These major spines and many smaller streets cover an extensive area of the centre that can be enjoyed on foot and bike. The transformation of the historic area into a pedestrian priority zone enables and invites walking and biking by making these active modes of transport comfortable, safe and enjoyable. These attributes result from applying the principle of "filtered permability" which selectively restricts the number of roads that run through the centre. While certain streets are discontinuous for cars, they connect to a network of pedestrian and bike paths which permeate the entire centre. In addition, these paths go through public squares and open spaces increasing the enjoyment of the trip(see image). The logic of filtering a mode of transport is fully expressed in a comprehensive model for laying out neighbourhoods and districts � the Fused Grid.
The main railway station is Munich Hauptbahnhof, in the city centre, and there are two smaller main line stations at Pasing, in the west of the city, and Munich Ostbahnhof in the east. All three are connected to the public transport system and serve as transportation hubs.
ICE highspeed trains stop at Munich-Pasing and Munich-Hauptbahnhof only. InterCity and EuroCity trains to destinations east of Munich also stop at Munich East. Since 28 May 2006 Munich has been connected to Nuremberg via Ingolstadt by the
