Ove Arup & Partners International, Mouchel and WSP Parsons Brinckerhoff have been appointed as consulting engineers for phase two of the High Speed 2 (HS2) project between Birmingham and Crewe.
The contract paves way for the North to benefit from HS2 six years early, a key recommendation of HS2 chairman Sir David Higgins in his 2014 report.
The HS2 project will feature 400m-long trains that operate at speeds of up to 360kph.
The consultants will provide detailed structural design and environmental services for the route.
They will also help developer and promoter HS2 Ltd prepare a second hybrid bill to extend the new rail link to Crewe by 2027, one year after the rest of phase one opens.
Ove Arup will provide civil and environmental services, WSP Parsons Brinckerhoff will deliver railway systems designs and engineering, while Mouchel will work on site access, land referencing and stakeholder engagement services.
HS2 CEO Simon Kirby said: "Bringing HS2 to Crewe six years early will dramatically boost connectivity and improve journeys for millions of people travelling between London, the Midlands and the major cities of the north.
"That’s why I’m pleased to confirm that we have appointed Arup, Mouchel and WSP Parsons Brinckerhoff to help us push forward with the next stage of the detailed design and help prepare the draft legislation we will need to get Birmingham to Crewe open by 2027."
According to WSP Parsons Brinckerhoff, its contract was expected to be worth about £15m over five years.
In addition to railway systems services, the WSP Parsons Brinckerhoff team of engineers and planners will be responsible for providing construction planning, operations planning, expert advice, detailed modelling, systems engineering and assurance.
WSP Parsons Brinckerhoff has provided rail systems design and development work on Phase 1 of the project.
