On behalf of the rail operator Thalys International, Ricardo Certification has completed a test programme with the train control system ERTMS Level 2 Baseline 3 for the Dutch section of the route. The Thalys high-speed trains were already equipped with ERTMS between 2005 and 2009 to use the HSL South between the Netherlands and Belgium, but with an older Baseline. The Thalys trains need to be upgraded to the newer version for when the the track will eventually be equipped with ERTMS Baseline 3.
