Birmingham Metro extension at HS2 Curzon Street: interface design notes for engineers
Reviewed by Tom Sullivan
First reported on New Civil Engineer
30 Second Briefing
Work has started on the final link of Birmingham’s Eastside Metro extension within the HS2 Curzon Street station site, connecting the existing West Midlands Metro to the new high-speed rail terminus. The section will thread new tram tracks, overhead line equipment and utilities through a constrained city-centre rail interchange footprint, requiring tight coordination with HS2 piling, station box construction and adjacent highway works. For civil and rail engineers, the interface design and staging around Curzon Street will be critical for future multimodal capacity and passenger flows.
Technical Brief
- Construction start within the HS2 Curzon Street footprint fixes the Metro interface staging baseline.
- Works are being delivered under the existing Eastside Metro extension contract, avoiding a separate procurement.
- Curzon Street activities must be sequenced around HS2 piling, station box excavation and superstructure works.
- Tram infrastructure installation includes embedded track slab, overhead line foundations and utility diversions in a rail-constrained box.
- Access for construction plant and materials is restricted to HS2-controlled worksite haul routes and time windows.
- Temporary traffic management on surrounding city-centre streets must coordinate with HS2 highway realignments and closures.
- Interface risk management will rely on integrated HS2–Midland Metro Alliance programmes and shared possession planning.
- Lessons on multi-operator station box integration will be directly applicable to other UK rail–tram interchanges.
Our Take
HS2’s Birmingham works at Curzon Street sit alongside other West Midlands structures like the Water Orton viaduct in our coverage, signalling that complex interface zones around live highways and dense urban railheads are now a major delivery focus rather than just rural mainline civils.
With HS2 Ltd already seeking a 10-year professional services partnering arrangement, the Birmingham Eastside Metro connection at the HS2 Curzon Street station site is the kind of long-lived interface asset that will probably demand sustained systems integration, asset management and urban realm expertise beyond initial construction.
