What we do

Railway electrification support, governed end to end

One team across consultancy and software — so the standards we apply on track are the standards built into the tools.

All services

OLE & E&P delivery

Expert E&P and OLE support on major projects and maintenance — design, assessment and interface management, on site or remote.

Fault response & clarity

Front-line fault investigation — bringing calm, source-led judgement to live problems on the system.

Technical authoring & engineering

Technical authoring, reference packs and material schedules ready for maintenance and construction — with design review and document reviews, traced to source.

Digital & AI enablement

Digital tools designed around your requirements — paperless surveys, instant drawing breakdown, reference packs and schedules, built to integrate with your existing systems.
The tool suite

An OLE consultancy that builds the tools it wished existed

Each tool is framed honestly — in development, governed, review-required. The discipline is the point.

Tools & platforms
In development

OGMS

Governed OLE Management System

Search and break down OLE drawings instantly, then generate technical reference packs and material schedules ready for maintenance and construction — end to end, in one governed record.
In build

Dropper Calculator

Per-span dropper schedules

System-height-aware schedules; unknown heights stay review-required, never fabricated. Single-dropper and full-span modes.
Review-required

IsoPlan

Intelligent isolation planning

Intelligent isolation planning — a DEP register and isolation case engine that builds and checks isolation plans, source-recognised and review-required.
Digital tools

Got a process stuck in a spreadsheet? We build the tool.

Digital tools designed around your requirements — moving manual, outdated practice into governed systems, used in the office or remotely and linked to what you already run.

Source-led, governed AI

Nothing is admitted as truth without a competent OLE checker

Modern, AI-native workflows — with railway judgement kept in the loop. Every output is REVIEW_REQUIRED by default, traced to its source inputs, and never presented as operational, geometry or isolation authority.

Governance is the feature, not the friction.

Source-led
Every output reads and writes the same governed record, traceable to the documents it came from.
Checker-approver
No safety-critical truth is admitted without a competent OLE checker signing it off.
Review-required
Reviews and sign-off are built into the workflow — never bolted on after issue.
