Disclaimer

The Open Rail Corpus v1 is a reference donation, not a certified standard. Content must be validated by qualified engineers before operational use in safety-critical rail applications.

What this corpus is

• A public, CC BY 4.0-licensed body of failure-mode reference content
• Structured against named regulatory catalogs with per-section citation
• Open for use, adaptation, and extension under the license terms
• Published and maintained by Kerne Systems, a brand of Gehrig Partner AG

What this corpus is not

• Not a certified standards output. No ISO, IEC, CEN, or other standards body has ratified this document or its bundles.
• Not a warranty of completeness. Every scenario covers a specific asset class, a specific regulatory catalog, and a specific set of failure modes. Gaps exist and are not hidden.
• Not a replacement for SAP EAM, SAP APM, PiLog iFoundry, Prometheus MDG, Prospecta, IBM Maximo, Oracle EAM, or any existing master-data or asset-management platform.
• Not operator data. Scenario A's 297 failure modes are transcribed and structured from the publicly-published BAV Fehlerkatalog (corpus_source = bav_fk_v12_2021, source = regulation). They are a reference catalogue anchored on public regulation, not the exhaust of a specific fleet's operational history.
• Not a complete FMEA. Severity and likelihood scores are indicative, not actuarially calibrated. Operators should re-score against their own exposure, failure-rate data, and consequence tolerances.
• Not a substitute for a qualified Reliability-Centered Maintenance study conducted by competent engineers with access to operator-specific context.

Generated content

Portions of the corpus content have been produced with AI assistance, structured against named public sources and then reviewed. This is disclosed transparently via the source and corpus_source fields on every failure-mode record. Generated content requires engineering validation before operational use. Consumers of the corpus are responsible for their own validation pipeline.

Warranty

This corpus and the artefacts it contains are provided as-is. No warranty, express or implied, is made as to completeness, fitness for any particular purpose, freedom from error, or suitability for safety-critical operations. Liability for operational use of corpus content rests with the user, not with Kerne Systems or Gehrig Partner AG.

The BAV Fehlerkatalog (Catalogue of irregularities) is a public regulation published by the Swiss Federal Office of Transport (FOT, German: Bundesamt für Verkehr, BAV). References cite Version 12.0 (effective 01.01.2021) as the structural basis of the failure modes, with forward reference to the currently in-force Version 18.0 (effective 01.01.2026, reference no.
