The city runs a small rather effective system of trams and buses. The two most important nodal points are the main station and Bismarckplatz. Bus #32 and #33 connect the main train station Hauptbahnhof with the old city area; detailed maps, schedules and routes can be found online. A mountain railway runs between four stations including the castle, linking the old city on the level of the river with the summit of the Königstuhl Mountain, about 400 m 1312 feet above the city.The "Heidelberg Card," a tourist pass that includes public transportation, many museums, and the lower section of the mountain railway a separate fare is required for the upper section, can be bought at the tourist information center located just outside the main station.
