A few questions regarding the Seilbahn...

1. Would a one day all inclusive public transportation ticket for Koeln also cover the ride on the Seilbahn, or is it a seperate ticket?

2. Is the Seilbahn within walking distance from the Hauptbahnhof, or is it better to take a strassenbahn or train?

3. Is it usually crowded, or do the lines move fairly quickly?
