East Coast Digital Programme (ECDP)

East Coast Main Line (southern section), UK · 2020–ongoing (with initial phases earlier) · £2.4bn (Whole Life Cost, 2021 estimate)

The judgement call

Account-gated at launch

The programme aims to establish new national capabilities for digital signalling deployment. - Lessons learned from previous digital signalling deployments have been incorporated into the design and delivery plan. - Cross-industry partnership is crucial for successful implementation.

Key engineering challenges

Transitioning from traditional lineside signalling to in-cab digital signalling (ETCS) on a busy, operational main line. - Ensuring interoperability and seamless integration of new digital systems with existing infrastructure and rolling stock. - Managing disruption to passenger services during significant upgrade works and testing phases.
