Hannover's Stadtbahn, a mix of underground and overland trains, makes it easy to get around the city. Tickets can be brought from stations or machines and are valid for two hours. There is no weekly ticket, but the HannoverCard gives you three days' free travel, as well as concessions at various attractions. If you're travelling less than three stops, save with a Kurzstreckenticket (short journey ticket), costing ¿1.10.
