Berlin Hauptbahnhof (Central station)
Photographed on 22 September 2009, this is the largest interchange and 2-level station in Europe.
It is located on the site of the historic Lehrter Bahnhof, and until it opened as a main line station on 26 May 2006, it was a stop on the Berlin S-Bahn suburban railway temporarily named Berlin Hauptbahnhof–Lehrter Bahnhof. The upper level of the station has six tracks (two of which used for the Berlin S-Bahn) and eight on the lower level (two more are reserved for the U55). There is no rail connection between the upper and lower level track in the station area (or anywhere else nearby). 1,800 trains call at the station per day and the daily number of passengers is estimated to be 350,000.
During its construction 1.5 million cubic metres of soil were removed by barge, which would otherwise have resulted in a 1,300 km long convoy of trucks.
The top sections of the four 70-metre high towers were lowered like the arms of a bascule bridge to form an arch, and were then locked in place. Composed of panes of glass, none of which resemble one another, the glass roof was completed in a record time of just four months. A total of 85 kilometres of steel cable holds the roof secure in wind and weather.
See the Berlin Hauptbahnhof web site for more details of this fantastic structure, the like of which I have never seen before.
