Bondholder and Derby-based manufacturing giant Bombardier is working with Hitachi Rail on a joint bid to build a fleet of 225mph HS2 trains.
Bombardier Transportation will tender for the £2.75bn contract in partnership with Hitachi.
The companies had previously put forward separate bids to build and maintain the 54-train fleet which will be used on the first HS2 phase between London and Birmingham.
If the joint venture is chosen by the government, the trains would be built in Bombardier’s Derby plant and Hitachi’s base in County Durham.
Richard Hunter, Bombardier’s UK managing director said “By joining together in partnership with Hitachi we will combine both companies' global high-speed expertise with unrivalled British experience.”
It is expected that the tendering process will start later this year, with the contract awarded in late 2019.
Alstom Transport, Patentes Talgo, Siemens and CAF have also been shortlisted.
