Hauptbahnhof

Berlin’s Hauptbahnhof in the district of Moabit was opened in May 2006. Up to then there were two central railway stations, Zoo Station (Zoologischer Garten) in the West and Ostbahnhof in the East. 

To confuse things, Ostbahnhof was called Hauptbahnhof from 1987 to 1998 and Hauptbahnhof - a former S-Bahn station - was called Lehrter Bahnhof from 1871 to 2006. The renaming of Lehrter Bahnhof caused enormous protests by the inhabitants, so the officials wisely decided to call the new station Hauptbahnhof-Lehrter Bahnhof, hoping that nobody would use that lengthy name and the part of Lehrter Bahnhof soon would vanish. They were right.
Zoo station, formerly something like Downtown Berlin, is now downgraded to a regional railway station.

The opening ceremony was marred by a drunken 16-year old youth, who stabbed visitors with his knife. Forty-one people were hurt, six seriously, before the youth was arrested. According to the police, the youth says he cannot remember his act of violence and is still denying it. He was charged with attempted murder and was sentenced to seven years in prison for attempted manslaughter in 2007.

In January 2007 two supporting beams of the structural frame tore loose during the European thunderstorm Kyrill, one of them falling down to the pavement. Luckily Hauptbahnhof had been not operational due to the complete cancellation of train services in Germany and nobody was injured.
