After the east-west roof of the new railway station Lehrter Bahnhof in Berlin was already executed, the north-south roof has to be completed in the second phase of construction. The north-south roof with its two main entrances is located between the two buildings shaped like a bridge spanning over the east-west roof.
The design principle of the new 44 m wide and 210 m long northsouth roof corresponds to that of the existing east-west roof. Analogously, the filigree construction was arranged between cable braced girders. Also here a maximum of transparency is guaranteed by means of a framework of longitudinal and transverse girders carried by diagonal cable structures. Due to the fact that the main girders do not run in a parallel direction,there are diverse geometric measurements for all glass panes.
In the north and the south, the railway station is enclosed by two fully glazed main entrance facades with a size of 28 x 44 m each. The facades consist of point-supported glass panes. The supporting structure is made up of vertical cables and horizontal glass fins corresponding to the frame girder principle.
The roof structure including the glazing was pre-assembled at some distance from the railroad tracks and subsequently moved to its permanent location in individual segments, which helped to reduce any disruptions of the train services to a minimum.
