About Redwell
Redwell UK was established in 2007 and brings over 30 years of collective rail industry experience to every project.
We specialise in managing the complex interface between developers, contractors, and rail authorities. Our team has extensive experience working with Network Rail's Asset Protection & Optimisation teams, TfL Infrastructure Protection, and Edinburgh Trams.
We act as a trusted extension of your project team — coordinating agreements, submissions, monitoring, and engineering compliance so you can focus on delivery while we protect your programme at the railway boundary.
What we do
You don’t have to learn Network Rail’s agreement process — we handle the establishment of Basic Asset Protection Agreements (BAPA) and full Asset Protection Agreements (APA) end to end, so you can focus on delivery.
BAPA · APA · NR & TfLEvery submission is reviewed for completeness before it reaches Network Rail or TfL — reducing the risk of rejection and resubmission delays across Form 1, Form 2, Form 3, RAMS, EPPs and Construction Phase Plans.
Form 1 · Form 2 · Form 3 · RAMS · EPPNo submission sits forgotten. We track every live item against the 20 working day review window, chase overdue responses before they become a problem, and keep your programme protected.
20WD tracking · ReportingWhen structural monitoring is required, we take on the Duty Operations Engineer (DOE) function — managing trigger threshold reviews, convening the Engineering Review Panel, and keeping the Emergency Preparedness Plan current.
DOE · EPP · ERP · NR/L2/CIV177Where the project needs it, we step into the Contractor’s Responsible Engineer (CRE) role under NR/L2/RSE/02009 — giving you a single accountable point of contact for the entire engineering management interface.
CRE · CEM · NR/L2/RSE/02009Working near the Edinburgh Tram Network brings its own process. We manage the full Authority to Work (AtW) submission via Permit+, so your team isn’t learning a new system under programme pressure.
AtW · Permit+ · ET/EM/005-GOur approach
We don't just process paperwork — we act as a trusted extension of your project team at the railway boundary. That means understanding your programme pressures, anticipating where Network Rail or TfL are likely to push back, and managing the relationship proactively rather than reactively.
Every submission we coordinate is reviewed for completeness and quality before it goes to the authority — because a rejected or incomplete submission doesn't just cost time, it costs programme. Our job is to protect that programme by getting it right first time wherever possible, and by chasing hard when an authority response is overdue.
You deal with one point of contact who understands both the technical requirements and the commercial pressure you're under — not a rotating cast of case handlers.
Case study
Overview
A £26 million design and build project for Whitbread, refurbishing an existing four-storey warehouse into a new five-storey, 258-bedroom hotel. The rear elevation of the building sat directly adjacent to Network Rail mainline services into Liverpool Street, with restricted site access across all boundaries.
| Client | Whitbread |
| Project Manager | TowerEight |
| Principal Contractor | Gilbert-Ash |
| Rail Interface Manager | Redwell UK Ltd |
The challenge
Partial demolition and extensive basement excavation directly adjacent to live mainline track risked structural movement affecting Network Rail's infrastructure, including Overhead Line Equipment (OLE) gantries. Continuous, verifiable assurance was required throughout demolition and construction to keep the railway operating safely.
Our role
Redwell acted as Rail Interface Manager throughout design and construction, coordinating all submissions to Network Rail and managing the authority interface from first engagement through to completion. As works progressed adjacent to the OLE gantries, Redwell took on the Duty Operations Engineer (DOE) function — overseeing 24-hour structural movement monitoring and reporting findings to Network Rail on a daily basis throughout the demolition and construction phases.
Outcome
The hotel was delivered with the railway boundary fully protected throughout demolition, excavation and construction. Daily reporting gave Network Rail continuous visibility of structural movement against agreed thresholds, while Redwell's coordination of the design and construction submissions kept the authority interface moving in step with the project programme.

Cladding & fire safety
Cladding replacement and fire safety remediation projects near the railway almost always trigger Network Rail or TfL asset protection requirements — involving scaffolding, cranes, temporary works and structural monitoring close to live tracks.
Redwell removes the complexity by managing the full asset protection process on your behalf, allowing your team to focus on safe and timely delivery of the cladding works.
We act as a trusted extension of your project team — ensuring all works near the railway are properly coordinated, compliant and delivered without unnecessary programme delays.
