(old tracks 5, 6, 7 and 7a), including the old pedestrian overbridge, were demolished by March 2008. Then the rest of the glass roof construction and the platforms underneath were built with tracks 8, 9 and 10. Commissioning took place on 30 November 2008 after a 27-hour total blockade. In the process, the southern long-distance platform 9 was put into operation, first as a 320-metre-long bay platform without overhead wire, and platform 10 was opened with a provisional connection until two subsequent bridge structures were completed in the eastern exit. At the end of May 2012, in a 64-hour possession, additional tracks for the high-speed lines were integrated east and west of the station with a length of 12 kilometres. The platforms 9/10 were now connected in both directions and its full length of 420 metres was usable as an ICE platform. In addition, the new southern entrance to the Flutgraben was handed over and the waiting room was redesigned. A crossing structure was built east of the station in Daberstedt to allow trains on the high-speed to Leipzig to pass over the tracks of the lines from Sangerhausen and Wolkramshausen. At Pentecost 2013, the structure was put into operation during a further blockade of the node. The commissioning of five tracks in the western part of the station took place at that time. A total of nine full possessions are planned for the integration of the two new lines. A total of €336 million had been invested up to May 2012 of the total estimated cost of €480 million. Several dozen companies and more than 300 people were involved in the project (as of August 2014). The station was fully blockaded from 20 to 22 November 2015 for the commissioning of additional tracks. Two further construction stages, each requiring a full possession, are still outstanding. At the end of November 2017, there was a blockade to allow the installation of a new software version of the ETCS. After the completion of the work, the running speed will be raised to 100 km/h. In a second stage of construction, the line from Eisenach is to be connected with the high-speed lines to Leipzig. Due to a lack of funds, this is only an option for which appropriate land has been reserved. Located in the area of the station are two of the three electronic interlocking subcentres (Erfurt and Erfurt NBS),
