Berlin’s Hauptbahnhof

Berlin’s Hauptbahnhof — the city’s huge and thundering main train station — is one of Europe’s mightiest, with several levels of tracks serving over a thousand trains a day and a vast shopping mall of commercial activity. While a massive public expense, Germans consider infrastructure like this a good investment for both business and for everyday people. Just being here, for a train enthusiast like me, gets me all giddy. What train stations do that for you?
