The job covers the design and build of the signalling systems that will control trains travelling at speeds of up to 360km/h and up to 25 years of technical support.

Instead of traditional coloured lights, HS2 will use a high-tech signalling system that feeds information directly into the cab, allowing faster and more frequent services.

The start of the formal procurement process for this second set of ‘rail systems’ contracts follows on from the recent launch of the track systems contest.

HS2’s procurement and commercial director, David Poole said: “Our state-of-the-art Command and Control Systems and Traffic Management systems will allow HS2 to offer fast, frequent and reliable low carbon journeys for millions of people every year.

“I look forward to our team working with the suppliers who come forward and together ensuring that we deliver best quality and value for the project.”

HS2 is hoping to attract up to four bidders, with shortlists set to be announced next year with contract award around 2022.

The Control, Command, Signalling and Traffic Management Systems contracts will utilise European Train Control System (ETCS) signalling and the latest TM technology.
