TS 50701railway cyber clause map
EN 5012xRAMS & safety-case spine
Freethe EU regulations, every tier
CLC/TS 50701 — the railway application of IEC 62443 — is surfaced as a clause map with Ansvar cross-references, never the reproduced standard: the railway asset and zone model, zones & conduits, the initial and detailed risk assessments, security-level targets and the cybersecurity case. It sits on the EN 50126/50129 RAMS and signalling safety-case spine, bridges into the shared IEC 62443 industrial-cyber mapping, and is grounded in the railway rows of the live ENISA transport threat landscape. NIS2 lands on rail operators as essential entities; run the rail TARA or a NIS2 gap analysis over signalling, rolling stock and trackside estates.

what you can do
Workflows that turn it into evidence
Rail TARA
threat analysis & risk assessment off the rail TARA workflow, following the CLC/TS 50701 initial + detailed risk-assessment shape — an available analysis, not a CSM-RA determination or an assessment-body verdict
STRIDE threat model
over signalling / CCS, rolling stock, TMS and trackside OT, grounded in the 50701 zone model
NIS2 gap analysis
Directive (EU) 2022/2555 Art. 21 for rail essential entities
IEC 62443 zone & conduit gap analysis
the shared 62443 clause map applied to the railway zone model
Document review, paragraph-cited
cybersecurity cases, risk assessments and signalling documentation
Threat-model workflows run on Premium and above (5 runs a month on a system you describe); document-grounded workflows run on Team and Company. Every tier runs the same corpora as cited research inside your own AI client.
Questions buyers ask first
- Do you serve the CLC/TS 50701 or EN 50126/50129 text?
- Not by default — railway standards are surfaced as clause maps with Ansvar-authored cross-references, addressable against your licensed copy. IEC 63452, the emerging international successor to TS 50701, is catalogued by status and scope only. Through the SIS-licensed standards module, any ISO, EN or SS standard SIS publishes can be licensed in and served cited verbatim inside your workflows; see /standards.
- Do you cover the EU rail directives, CSM-RA or the TSIs?
- Not yet as served text. The Rail Interoperability Directive (EU) 2016/797, the Rail Safety Directive (EU) 2016/798, CSM-RA (Reg (EU) 402/2013) and the CCS TSI are on the ingestion roadmap, and the clause map already cross-references them by CELEX so the mapping is ready. What is served today at article level is the horizontal stack — NIS2 and CER. We will not imply coverage we cannot ground.
- How is this different from the Industrial / OT page?
- Industrial / OT takes the plant operator's view — IEC 62443 zones, conduits and live ICS advisories. This lane is railway-specific: CLC/TS 50701's railway zone model and cybersecurity case, layered on the EN 50126/50129 signalling safety case. The IEC 62443 mapping is shared between both.
