Exploring Network Rail’s 10-Year Signalling £4bn Framework Program
In a landmark initiative aimed at revolutionising the UK’s railway infrastructure, Network Rail has unveiled its ambitious 10-year Signalling Framework Program. This plan is set to modernise the UK’s railway signalling systems.
Framework Awards
Digitalising the UK’s vast & complex railway, which covers 20,000 miles of track, will need to be done in phrases. Six companies were awarded contracts for the provision of conventional & digital signalling services under the Train Control Systems Framework. The framework runs from 2024 until 2034 and is worth £4bn (£3bn = digital signalling and £1bn = conventional signalling).
The contracts were awarded over two lots:
Lot 1: Conventional signalling
Alstom
AtkinsRealis
Hitachi
Siemens
Lot 2 – Digital signalling (using European Train Control System technology)
Alstom
AtkinsRealis and CAF
Siemens
Thales & VolkerRail
The UK’s railway network, one of the oldest in the world, faces significant challenges with its aging signalling systems. Many of these systems, some of which date back several decades, are becoming increasingly difficult & costly to maintain. The current infrastructure limits the capacity and efficiency of the rail network, causing delays & reducing the overall quality of service.
Key Objectives
Enhanced Safety: Modern signalling technology will significantly improve safety by reducing the risk of human error and enabling more precise control over train movements.
Increased Capacity: Upgrading to digital systems will allow for more trains to run on the same tracks, effectively increasing the network’s capacity without the need for extensive physical expansion.
Improved Reliability: Digital systems are less prone to failures and can be monitored & maintained more efficiently.
Sustainability: The new systems are designed to be more energy-efficient, contributing to Network Rail’s broader environmental goals.
Technological Innovations
European Train Control System (ETCS): Will replace traditional line-side signals with in-cab signalling, providing continuous communication between the train & the trackside equipment.
Traffic Management Systems (TMS): Will optimise train schedules & real-time traffic management, ensuring smoother operations & minimising delays.
Digital Infrastructure: Implementation of fibre-optic networks & advanced data analytics will support the robust communication & monitoring required for modern railway operations.
Implementation
The 10-year plan will be rolled out in phases to ensure minimal disruption to current services. Key routes & regions have been prioritised based on traffic density, current system age, & strategic importance. Programs already started include The East Coast Digital Program & The TransPennine Route Upgrade.
