 The situation changed with German reunification and it was decided to complete the extension and open the Hermannstraße U-Bahn station.The scheduled reopening of the Ringbahn on 17 December 1993 created time pressure, because work on the U-Bahn station had to begin before then.The work included renovation of the existing tunnel and partial platform, construction of the remainder of the platform and the creation of a 320 m long turn-around.
