Intermediate Roof Structure for Amsterdam Central Station, The Netherlands

Three tracks within Amsterdam Central Station (CS) were not covered by roof structure. This was rather uncomfortable for passengers, and therefore it was decided, when the existing roof structures were restored, to build an intermediate roof over the three uncovered tracks. The Intermediate Roof of Amsterdam CS closes the gap between the existing roof structures to cover all existing tracks. Its design was highly influenced by the architectural requirements imposed by the historic surroundings and by the complex erection method in a railway station under operation. The Intermediate Roof is a modern, transparent structure with which Amsterdam CS is ready for the expected train traffic in the 21st century.
