The design phase will run concurrently with ongoing civil engineering projects, now nearing their peak phase. This synchronization ensures rail systems contractors are ready to mobilize once civil works conclude.

Advancing Rail Infrastructure: HS2 Construction Milestones

Track Systems, Lots 1, 2, and 3

Ferrovial Construction and BAM Nuttall JV will lead the track infrastructure development, including construction logistics management. They will oversee testing and commissioning while serving as Principal Contractor for trace-related works.

The project scope spans Old Oak Common to Birmingham Curzon Street, covering key infrastructure like the Calvert Maintenance Depot. Their responsibilities also include interfacing with the Washwood Heath Rolling Stock Depot and Handsacre Junction’s connection.

Switches, crossings, and pre-cast slab tracks will be supplied via contracts with Voestalpine and PORR UK. Rail components will be provided through Network Rail, while logistics and installation coordination fall under Ferrovial BAM.

Overhead Catenary Systems (OCS)

Colas Rail will handle the design and installation of Overhead Catenary Systems using SNCF Reseau’s V360 OCS. This advanced system, certified for speeds up to 360 km/h, will supply power to HS2’s cutting-edge trains.

The contract includes system testing and commissioning, ensuring compatibility with the high-speed rail’s demanding requirements. The V360 design exemplifies the latest in railway electrification technology.

Technology and Connectivity Enhancements in HS2 Construction

Operational Telecommunications and Security Systems

Siemens Mobility will implement advanced telecommunications and security systems to ensure operational efficiency and safety. This involves designing, manufacturing, and commissioning state-of-the-art solutions tailored for high-speed rail.

Spare capacity on the optical fiber network could be offered to third-party providers. This could enhance broadband services in rural areas, bridging connectivity gaps for remote communities.

Third-Party Telecommunications

Hitachi Rail and Telent Technology Services JV will provide mobile communications and emergency services systems. They will also supply the station data network, ensuring reliable connectivity for passengers and operational needs.

Their responsibilities include designing, installing, and maintaining telecommunications systems that will support both everyday rail services and critical emergency responses.

Command, Control, Signaling, and Traffic Management (CCS & TM)

Siemens Mobility will deliver digital CCS & TM systems to facilitate faster and more frequent train operations. This replaces traditional signaling with cutting-edge technology for enhanced efficiency.

Their role covers system design, installation, testing, and maintenance, ensuring seamless operations. These systems will remain supported through technical services, even after the initial handover.

Engineering Management System

Siemens will implement a digital Engineering Management System to provide real-time monitoring and control. This Supervisory Control and Data Acquisition (SCADA) solution will enable efficient asset management.

The system’s integration allows operators to oversee railway assets remotely, enhancing safety and reliability. Long-term technical support will ensure continued performance for up to 25 years.

Real-time data from the Network Integrated Control Centre in Birmingham will help manage railway systems effectively. This facility underscores HS2’s commitment to delivering a world-class rail service.

A separate contract for the Washwood Heath depot and Network Integrated Control Centre is scheduled for award next year. This additional investment reflects the project’s scale and its transformative potential for UK rail transport.
