World's most expensive train station, the World Trade Centre Transportation Hub, opened on 3 March 2016 in New York, the United States of America.
Santiago Calatrava, the Spanish-Swiss architect who unveiled his ambitious design 12 years ago, removed a barrier at the entrance of the Oculus, a giant oval hall with walls of steel ribs and glass.
Built next to the site of the destroyed Twin Towers, the World Trade Centre Transportation Hub is expected to eventually serve more than 200000 daily commuters.
Initially budgeted at 2 billion US dollars, the station ended up costing 3.85 billion US dollars that earned it the title of the most expensive station in the world.
The building has an elliptical shape. The space measures 107 metres long by 35 metres at its widest point.
