UK: Between June 2021 and January 2023, the German manufacturer filed a series of claims against the award of a contract for the supply of 54 high-speed electric trains to the Alstom–Hitachi Rail joint venture.
In these claims, Siemens Mobility accused High Speed Two (HS2), the project operator, of evaluation errors at several stages of the tender process, favouring Alstom and Hitachi Rail’s bid, and conflict of interest.
The High Court in London dismissed all of Siemens Mobility’s claims, finding them to be insufficiently substantiated, and stated that it had found no breaches of the procurement rules.
In March 2021, another bidder, Talgo, launched a legal challenge claiming that its bid had been unfairly rejected. In this situation, HS2 managed to reach an agreement in mid-summer of the same year.
