European Traffic Management System (ERTMS) Early Works - Stage 2 (Develop) Support Services

Description

London St. Pancras Highspeed's current TVM430 signalling system is reaching obsolescence, creating increasing operational, safety and resilience risks. Without intervention, system reliability and lifecycle issues are expected to significantly impact network performance from the 2030s. Stage 1 of the upgrade programme—delivered with SYSTRA—produced an Operational Context Document, a Technical Strategy with long‑ and short‑list options, and a Strategic Outline Business Case (SOBC) in WebTAG format. This completed the Rail Network Enhancements Pipeline (RNEP) Stage 1: Determine. LSPH and its stakeholders are now progressing to RNEP Stage 2: Develop, requiring specialist external consultancy support throughout 2026. Stage 2 will resolve key strategic questions, including the preferred technology solution for replacing TVM430, the funding approach within the HS1 regulatory and concession framework, the suitability of innovative commercial models, strategic opportunities, and the project delivery and scope choices that minimise whole‑life cost. Additional strategic issues may be identified collaboratively during the process. Further information can be found within the attached document within the Portal
