The heart of Stuttgart 21, one of the most spectacular construction sites in Europe, lies in the Stuttgart basin. The new through station, the center of the future reorganized Stuttgart rail hub, is visibly taking shape. Work is currently underway on the last of 28 calice supports. Specialists from a wide range of disciplines are watching over the construction work on this highly complex site, and the focus in this film is on the surveyors. #stuttgart21 #contruction #deutschebahn ▬ More information ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ Deutsche Bahn's comprehensive information platform on the Stuttgart-Ulm rail project: http://www.bahnprojekt-stuttgart-ulm.de/ ▬ What is the rail project ▬▬▬▬▬▬▬▬▬▬▬▬▬▬ The Stuttgart-Ulm rail project comprises the reorganization of the Stuttgart rail junction (Stuttgart 21) and the new Wendlingen-Ulm line. The construction project is the largest expansion concept for public rail transport in Baden-Württemberg since the 19th century.
