While construction in Shanghai progressed, ThyssenKrupp was transforming what had only been a prototype TR-08 maglev vehicle construction facility in Kassel, Germany into a full-fledged manufacturing plant. The SMTDC ordered 15 vehicles to constitute
three 5-vehicle consists. Once the Kassel plant was fully converted to mass production, it produced one vehicle per month. The completed vehicles were then shipped to a facility constructed at the end of the Shanghai maintenance spur for final assembly. In addition to the maglev vehicles and guideway stator packs, ThyssenKrupp designed, fabricated, and shipped the eight bendable steel guideway switches for the system and supervised their installation.
