Overview
- HS2 confirmed the previously stated 2029–2033 window for Birmingham–London services cannot be achieved and said a formal comprehensive reset is in its advanced stage.
- New, credible cost and schedule ranges are being finalised as the programme tightens governance to stabilise delivery.
- Construction is being reprioritised to complete the Old Oak Common–Birmingham section, finishing civil works before installing track, signalling and communications systems.
- HS2 reports "peak production" with all 23 miles of deep-bore tunnels excavated on the opening section and about 70% of earthworks delivered.
- 2025 milestones include completing the Colne Valley viaduct, installing the first high‑speed platforms at Old Oak Common, excavating the Northolt and Bromford tunnels, and realigning a 749‑metre stretch of the River Cole, with £25.3bn in four‑year funding confirmed in June alongside tougher cost controls and more front‑line staff.
