£130bn The Loop rail concept: design and delivery lens for northern engineers
Reviewed by Joe Ashwell
First reported on New Civil Engineer
30 Second Briefing
£130bn rail proposal The Loop, championed by Riba president Chris Williamson, would form a high-capacity orbital route linking major northern English cities as an alternative to the cancelled HS2 northern leg. The concept envisages reusing and upgrading existing corridors where possible, with new high-speed sections to close gaps and create a continuous loop for intercity, commuter and freight services. For civil and rail engineers, the scheme would drive large-scale track, electrification, junction remodelling and station works across multiple legacy networks.
Technical Brief
- Scheme is costed at approximately £130bn, implying multi-decade, multi-phase procurement and delivery.
- Riba president Chris Williamson is the named proponent, giving the concept institutional architectural backing.
- Positioning as a “true northern powerhouse” frames expectations for large-scale regeneration around new and upgraded nodes.
Our Take
RIBA has already been vocal in our recent coverage about the lack of detailed infrastructure commitments in King Charles III’s first King’s Speech, so its backing for The Loop signals an attempt to steer the agenda towards large-scale regional rail rather than piecemeal schemes.
For contractors and designers, RIBA’s early positioning on The Loop echoes how professional bodies shaped expectations around sustainability and design quality on major London schemes, suggesting that any eventual procurement could bake in higher design and carbon-performance baselines from the outset.
