context_page_description: Stuttgart Hauptbahnhof is the primary railway station in the city of Stuttgart, the state capital of Baden-Württemberg, in southwestern Germany. It is the largest regional and long-distance railway station in Stuttgart, the main node of the Stuttgart S-Bahn network, and, together with the station at Charlottenplatz, it is the main node of the Stuttgart Stadtbahn.
  Located at the northeastern end of the Königstraße, the main pedestrian zone of the city centre, the main line station is a terminus, whilst the subterranean S-Bahn and Stadtbahn stations are through-stations. The station is well known for its 12-storey tower with a large, rotating and illuminated Mercedes-Benz star insignia on top; the tower and station building are city landmarks.
  Plans for the controversial Stuttgart 21 project to convert the main line terminus station into an underground through station include the demolition of the side wings of the building, together with the elimination of the platforms, tracks, and apron of the terminus station. The planned underground through station is configured at a 90-degree angle to the present station. Construction is scheduled from 2010 to 2019.
context_section_description: With the symbolic start of construction on 2 February 2010 reconstruction work began on the track apron; these were necessary for the construction of the cross-platform concourse at the end of the platforms.
  The contract to demolish the north wing was awarded to Wolff & Müller on 18 May 2010. The establishment of the worksite began on 30 July 2010 under police protection and the demolition of the facade of the north wing began on 25 August 2010.
  Work on the demolition of the south wing began on 13 January 2012 with the gutting of the building. The exterior demolition of the building began on 30 January and was due to be completed in March 2012. After a pillar of the platform canopy was damaged on 19 March, work was suspended for about three weeks. After further damage due to gale-force gusts on 1 July 2012, platform 15/16 was blocked off again and work started on the upgrade of the glass panes on all platform canopies.
  The approximately 110-meter-wide excavation was due to be bridged by two ten-metre-wide bridges by April 2014. In addition direct access was to be provided to the cross-platform concourse from both sides. Access to the Europaviertel district on the north side has been possible since 21 October 2013 and on the south side there has been access via the pedestrian walkways from the Mittlerer Schlossgarten since 24 January 2014. Both entrances are barrier-free.
  The repositioning of the cross-platform concourse was postponed several times. According to the planning status of March 2012, the cross-platform concourse was to be gradually advanced between July and December 2012. At the end of June 2012, just over 50 of the 61 planned construction phases had been completed on the track apron. Platform tracks 1 and 2 were re-connected without completing the planned construction of the new S-Bahn tunnel in this area. Construction of the new cross-platform concourse took place from late May 2013 to 22 October 2013 in 13 phases, requiring two platform tracks were blocked off. Deutsche Bahn reduced some train services during this period to reduce congestion of trains at the station. The preliminary work and the commissioning of the cross platform, 120 metres north of its original location, should have taken 18 months to complete, but actually lasted 45 months.
  A two-storey underground engineering building of 1,800 square metres was built under the former parking lot at the northern exit at a planned cost of €7.6 million between April 2012 and October 2013 (when the construction of the shell was completed)
  On 12 March 2012, the construction contract for the underground station, including the West, Cannstatter Straße and Nesenbach channels and the station access tunnel, was awarded to a consortium of the Züblin (manager) and Strabag companies. The formal award took place on 24 March 2012. The contract for the construction of the new central station was let for €323.4 million, which was a sliding price under the contract. The internal portion being built by Züblin amounts to around €300 million. Groundwater management is not part of the scope of the contract. The total contract value was €347.4 million in May 2016 and €364 million in August 2016.
  At the end of 2010, the lowest tender for the construction of the underground station amounted to about €360 million. The first contract planned to be let in late 2011 was delayed over price negotiations. Also technical questions led to delays. In addition to successful negotiations, technical optimisations, such as a change in the type of concrete, would have contributed to savings, according to a media report. Deutsche Bahn had calculated a price of €300 million based on its own data.
  In July, September and October 2012 trains derailed on the exit towards Feuerbach, which had been rebuilt in the course of the Stuttgart 21 project. Following the latest derailment, platform tracks 8, 9 and 10 were blockaded. In January 2013, Deutsche Bahn justified the derailments as being the result of "malfunctioning carriage buffers". A short-term technical solution developed by DB was rejected b
