News released by AFP and published on a site called Macaubusiness says that the Brenner Base Tunnel company BBT SE has terminated the subcontractor ARGE H51. Or as they put it, "put an end to its contractual relationship with ARGE H51".

BBT SE has no such press release on their website (yet). ARGE H51 was responsible for tunnelling between Pfons and the Italian border. According to Macaubusiness, BBT SE gave the reasoning for firing ARGE H51 as its "definitive refusal to provide contractually agreed services and a loss of trust”.

Can this be true?
