Normative safety documentation for railway teams — HAZOP, FMEA, FTA — guided, structured, compliant.

The Problem

Safety documentation costs more than it should.

Manual processes, fragmented tools, and missing expertise create avoidable risk and delay.

Method selection delays projects

Choosing HAZOP, FMEA, or FTA requires deep expertise most teams don't have in-house.

Documentation is error-prone

Switching between Visio, Excel, and Word creates inconsistencies that only surface in audits.

Norm compliance is manual

Verifying adherence to EN 5012x requires constant cross-checking that slows every phase.

Expert knowledge doesn't scale

Safety know-how lives in individual experts. When they're unavailable, the project stalls.

The V-Model defines the railway safety engineering process — and where documentation failures occur.

How it works

Five steps to compliant documentation.

Describe your system

Answer guided questions about your system structure and operational context.

Method is recommended

safeTwatch selects and configures the right analysis method automatically.

Run the analysis

Work through the structured analysis with built-in guidance at every step.

Evaluate results

Review findings, flag open issues, and confirm that all normative requirements are covered.

Export documentation

Get export-ready, norm-compliant documentation — no manual formatting required.

Mission

We build tools that make safety engineering accessible — for every team, regardless of their safety expertise.

Vision

A world where compliant safety documentation is generated, not written.

Safety engineering must be accessible to every team.

Quality comes from good tools, not from individual expertise.

Expert knowledge belongs in the system, not in someone's head.

FAQ

Frequently asked questions.

No — safeTwatch is not a Safety Case tool. It focuses on the analysis and documentation process: HAZOP, FMEA, FTA, and the associated normative evidence trail. A Safety Case is a higher-level argument structure that references this evidence. The two are complementary, not the same.
At launch: EN 50126 (RAMS), EN 50128 (software), EN 50129 (safety cases), and EN 50716. The workflow engine is built around the V-model as defined in these standards.
Railway and mass-transit engineering teams that need to produce normative safety documentation — regardless of whether they have dedicated in-house safety expertise. This includes systems engineers, safety managers, project leads, and technical consultants.
We're currently in private beta. Waitlist members will be the first to know — and get early access before the public launch. Join the waitlist to stay in the loop.
Existing tools assume you already know what to do — they're databases and editors for experts. safeTwatch guides you through the process: it recommends the right analysis method, walks you through each step, and generates the documentation. Less setup, less expertise required.
Get involved

Want to help?

safeTwatch is built by a small team. There are concrete ways you can contribute — and we're grateful for every one of them.

Domain expertise

Are you an active safety engineer with experience in EN 5012x processes? Your feedback on workflows, edge cases, and normative requirements is invaluable.

Financial support

We are self-funded and building in public. If you believe in what we're building, early financial support helps us move faster and stay independent.
