Signpost (not a knowledge pack) for the railway RAMS and signalling assurance standards: EN 50126-1:2017 and EN 50126-2:2017 (both with A1:2024) for the RAMS process, EN 50128:2011 (A1:2020, A2:2020) for software for railway control and protection systems, and EN 50129:2018 and EN 50129:2026 for safety-related electronic systems for signalling, plus the free CSM regulations and ORR guidance that cover the risk-process need. Contains no source content: each row carries only the designation…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Railway RAMS and Signalling Assurance Standards: Signpost (pointers only)

**This is a signpost, not a knowledge pack.** It carries **no standards-body content**:
no reproduced clauses, no normative text, no synthesised summaries of the standards.
EN 50126, EN 50128, EN 50129, and EN 50159 are paywalled with no redistribution grant
(Excluded under this repo's `docs/SOURCE-VETTING.md`), so they cannot be reconstituted
into a redistributable pack. What this skill does: tell you which document you want,
what it is for, who owns it, whether a free copy exists, and where to get the authentic one.

## When to use

You are working on railway RAMS, railway control software, or a signalling electronic
safety case and need to identify or cite the governing document: which standard covers
the RAMS process, which covers software, which covers safety-related electronic systems
for signalling, and which free text covers the risk-process need. Paywalled rows route
you to the owner. Free rows route you to the regulation or the ORR guidance. No row
names an in-repo pack.

How to install

The exact contents, by fingerprint
mdr add jgsystemsconsulting/jgs-se-knowledge-packs/rail-signpost@sha256:4719ea01f932c69a

The line at the top of this page pins the label git:20261014.6ac4320, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
