Rail
Delivering Safe, Reliable and Resilient Rail Infrastructure
The UK rail network continues to evolve, with ongoing programmes of maintenance, enhancement, electrification, capacity upgrade works and new infrastructure delivery. Rail assets often occupy geotechnically complex environments—steep embankments, deep cuttings, ageing earthworks and constrained corridors—all of which demand robust geotechnical assessment and design to ensure long‑term safety and performance.
North Geotechnics provides specialist geotechnical engineering expertise to support rail clients, contractors and designers in managing ground‑related risks and delivering efficient, compliant and resilient rail infrastructure.
Earthworks and Asset Management
Rail earthworks are critical assets that can significantly influence safety, performance and operational resilience.
North Geotechnics provides detailed stability assessments for embankments and cuttings. We can complete hazard identification and risk rating to support asset management. Following analysis of deterioration mechanisms, we can specify targeted ground investigation and design interventions such as soil nails, rock anchors, reinforced soil and retaining walls.
Formation and Trackbed
Track performance is heavily dependent on the behaviour of the underlying formation. We support clients with assessment of trackbed materials and subgrade conditions. We design formation improvement measures including drainage, capping layers, geogrid reinforcement and granular blankets. Our detailed design packages include full earthworks specifications as well as monitoring and verification requirements.
Structures and Foundations
New and upgraded rail assets often require specialist foundation input.
North Geotechnics provides foundation design for bridges, gantries, OLE masts, stations and ancillary structures. Ensuring compatibility with construction installation time frames and producing design packages to Network Rail standards.
Retaining Structure Design
Working within narrow rail corridors often requires innovative and efficient retaining solutions.
We specialise in the detailed design of embedded walls, cantilever systems, reinforced soil structures and hybrid solutions. Our designs are compliant to Network Rail standards and we work in partnership with project teams to ensure buildable designs.
Working Platform Design
Rail construction and maintenance activities involve heavy tracked plant, piling rigs and specialist machinery.
Safe platform design is essential and North Geotechnics can deliver working platform designs along with clear drawings, specifications and monitoring/verification guidance.
