Write, verify, and assess documentation with CyRail.

Rail safety and operational technology cybersecurity standards, in one platform. Designed by the people who do this work, defensible to assessors and regulators.

Safety (RAMS)

EN 50126-1 EN 50126-2 EN 50129 EN 50716

Operational Technology Cybersecurity (OTCS)

TS 50701 IEC 63452 IEC 62443-3-2 IEC 62443-3-3 IEC 62443-4-1 IEC 62443-4-2
Configure to your scope

Switch scope inside the tool.

CyRail covers two scopes today: safety (RAMS) and operational technology cybersecurity (OTCS). Your team works against the standards relevant to their scope, with the option to switch or combine. More frameworks coming as customers ask for them.

Capabilities

What CyRail Does

Tools that take the pain out of assurance.

Chat Assistant

Get fast, expert answers on rail safety and cyber standards. Ask questions against the standards themselves, or against documents you have uploaded. Built on specialist railway expertise, not a generic chatbot.

  • Standards-aware answers across RAMS and OTCS
  • Question your own uploaded documents
  • Citations back to source clauses
  • Built by railway engineers

Compliance Assessment

Assess single documents or small sets against your chosen standards. Ask targeted clauses, receive structured findings, and track corrective actions through to closure.

  • Best for 1 to 10 documents
  • Customisable question sets
  • Targeted corrective actions
  • Assessment history and revision tracking

Projects

Assess entire projects or change packs in one pass. Upload, organise by phase, and process at scale. Receive findings rolled up at document, phase, and project level so you can navigate from headline status into individual clauses.

  • Scales to 50+ documents
  • Phase structure built in
  • Document, phase, and project-level rollup
  • Ideal for full project reviews and change packs

Why CyRail

Why CyRail

Documentation for rail safety and operational technology cybersecurity has grown faster than the time available to assess it. CyRail helps your team work through that volume systematically, producing structured findings and corrective actions at the pace projects actually move. The result is an assurance record you can defend to an assessor, a notified body, or your regulator, without the manual rework that usually goes with it. Built by railway engineers who do this work themselves.

Testimonials

What engineers say

“It produced valuable assessment output that would cut through a lot of reading of documentation when evaluating multiple sources of information. Great for pulling together threads from across a documentation suite.”

Safety Critical Assurance Lead

“I liked the ability to ask additional questions on the assessment output to look for particular threads through the output.”
