The new train station in Manhattan will serve as an extension to the nearby Pennsylvania Station. The two inner courtyards are being roofed over with steel-and-glass structures. 2,936 aluminium-and-glass elements are fitted into each shell structure and 578t of steel are required. Every element of Moynihan Train Hall is unique, and therefore every operation in design, production, logistics and construction must be planned and carried out with maximum precision. Two true to scale mock-ups were recently built on seele’s testing grounds in Gersthofen. seele was granted "visual approval" from the architects at the end of October and has commenced to work on site since last friday.
