The Birmingham extension to Digbeth will serve the planned HS2 station at Curzon Street, separating from the existing West Midlands Metro line at Bull Street.
Around 1.7km of new twin-track will run from Bull Street to a new terminus at High Street Deritend.
The scheme includes four additional West Midlands Metro stops serving the east of Birmingham City Centre.
This new service will connect the Eastside regeneration area offering connections with New Street, Moor Street and Snow Hill Railway Stations, in addition to the planned HS2 station.
The scheme also includes a new bus interchange adjacent to Clayton Hotel Birmingham.
Work will be carried out by the Midland Metro Alliance, a team of planning, design and construction specialists working with WMCA.
It consists of rail construction specialists Colas Rail – with Colas’ partners Colas, Barhale, Thomas Vale and Auctus Management Group – and a consortium of design experts from Egis, Tony Gee and Pell Frischmann.
