The IP network will form the backbone of a new digital infrastructure that will enable the state-owned DB to remotely steer all operations in one of the largest rail networks in Europe, the article adds, citing Reuters.
The contract, which has not previously been reported, shows how German firms continue to use Huawei tech in what many consider to be critical infrastructure.
A DB spokesperson told Reuters it followed the reommendations of authorities, but under current IT security legislation it did not have to run network components by Germany's cybersecurity office, the BSI, unlike public telecoms network operators. It said it was up to the contractor - in this case, Deutsche Telekom Business Solutions, a subsidiary of Deutsche Telekom - to choose the components.
A BSI spokesperson said it was not aware of any law that determined the DB IT systems as "critical components".
