Hitachi Rail Europe will bid for the contract to build the HS2 trains in the North East, which could mean hundreds of jobs.
The rail manufacturer is head-quartered in London and builds trains at itsplant in Newton Aycliffe, County Durham.
Up to 60 trains will be needed to transport passengers at around 225 mph.
The contract, which is worth £2.75 billion, will be awarded in 2019.
Advance warning about the start of the bidding process was published on Friday by HS2 Ltd, the organisation responsible for developing the £55.7 billion project.
And Hitachi Rail Europe sales director, Nick Hughes, said the North East had the know-how to build the trains.
In a tweet Labour MP for Sedgefield Phil Wilson called the bid "great news" and said it could mean 100s of jobs and investment in the North East.
Transport Secretary Chris Grayling described the search for a trainmanufacturer as "a major step" towards Britain getting a new railway whichwill carry more than 300,000 people each day.
Mr Grayling said building and maintaining the trains will be a "greatopportunity for British-based businesses and suppliers" with the creation ofhundreds of jobs.
Construction work on phase one of HS2 from London to Birmingham will start in the spring, subject to its parliamentary bill getting royal assent in the coming weeks.
