People in Warwickshire are being encouraged to apply for HS2 jobs at pop-up roadshows across the county.
Bosses of the project say they will need 30,000 people to help deliver the high speed train network.
The event is in Leamingston Spa today, and other towns in the county this month.
One of the groups bidding to build the trains for the HS2 high-speed rail line has released this image to show what they might look like.
Derby train maker Bombardier and Japanese firm Hitachi said their "Great British" train, designed to reach speeds of up to 225mph, would be "the most advanced, customer-oriented train ever to run in the UK".
Bombardier and Hitachi are competing with Alstom Transport, CAF, Patentes Talgo and Siemens for the £2.75bn contract to build and maintain 54 trains.
Phase one of HS2 will eventually take passengers between Birmingham and London.
Alstom has unveiled its proposed design for HS2 which it says meets requirements for !a world class, modern and flexible train".
Nick Crossfield, Managing Director for Alstom in UK and Ireland, said: “Alstom’s vision is to make HS2 trains a timeless design classic, with a passenger experience that is as smooth, calm and spacious as it is high-speed.
Alstom is excited to unveil this proposed train for HS2, which is the most important economic regeneration project in Britain for decades. It will knit together the great cities of the midlands and the north as never before, and turbo-charge our regional economies".

HS2 rail link works that would have closed a busy road in Harefield have been postponed until the school summer holidays after Hillingdon Council threatened legal action.
The closure of Breakspear Road South was scheduled to begin on Friday, but has now been put back until the end of the school term on 19 July, according to correspondence provided by Council Leader Ray Puddifoot.
The delay was put in place in part to avoid school exam periods, a HS2 spokesperson said.
They said: “We have listened to local residents and their representatives, and we have taken this decision in response to their concerns – especially those about the potential impact on pupils and their families travelling to school exams.
“We will now work with the relevant utility companies to identify future dates when this essential work can be completed, and we will keep the local community informed as our plans progress.”
Work on building the HS2 high speed railway between Birmingham and London through Warwickshire is now supporting 9,000 jobs, according to figures released by the company.
More than 2,000 companies are working at 250 sites across the country to prepare for the start of construction of the line.
Eventually 30,000 people will work on the first phase of the £56bn railway, which is due to open in December 2026, HS2 Ltd said.
Work is continuing to construct the new Curzon Street station in the centre of Birmingham, which will be linked to the tram network as well as rail networks to the wider West Midlands.
