In total, Birmingham Curzon Street, Interchange, Old Oak Common and the new HS2 platforms at London Euston will need more than 160 lifts and 130 escalators.
TK Elevator, which employs around 400 people across the UK, has signed a framework agreement, expected to be worth between £207m and £316m depending on the number of lifts and escalators needed.
This flexible approach will allow HS2 to vary the number of lifts and escalators in line with station requirements as the designs are finalised.
As well as manufacture and installation, the framework also includes maintenance for up to 20 years.
The longest escalators will be at Old Oak Common, in west London, which will take passengers 13.5m up from the subsurface platforms to concourse level.
In total, the new station – where HS2 meets Crossrail services to Heathrow and the West End of London – will boast more than 50 lifts and escalators.
Inge Delobelle, CEO of TK Elevator in Europe & Africa, said: “We have a strong track record of supporting transport infrastructure projects across the world, and are confident that our proven expertise as well as our commitment to sustainability and high safety standards will help provide the best mobility solutions for this ambitious undertaking.”
