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.
