TS EN 15016-3

TS EN 15016-3 is the third part of the standard dealing with how modifications are handled in technical documents used for railway applications. In railway engineering, technical drawings and design data must remain traceable as equipment, infrastructure and system definitions evolve, so the disciplined handling of revisions is a core documentation issue rather than a purely editorial one.

This standard applies to railway organisations, their partners involved with technical documentation, and suppliers who prepare documents on behalf of railway companies or railway network users. It also covers the basic principles for a wide range of document forms, including transparency originals, plotter drawings, aperture cards, computer-readable media, photoprints, COM-fiches and computerised information sets. The intent is to keep the revision logic consistent even when the carrier or output format changes.

Why revision control matters in railway documentation

In general technical practice, revision control is about more than issuing a new drawing. It is about making the change visible, linking it to the previous issue and preserving a reliable history of the document. In railway work, that matters because design information moves across design, manufacturing, maintenance and operation. Clear modification handling helps reduce confusion between versions and supports consistent use of the latest approved information.

What this part defines at a practical level

• It sets out the basic basis for revising technical design documents in railway applications.
• It does not incorporate additional company-specific requirements; those remain outside the standard’s basic framework.
• The same revision principles are intended to apply regardless of whether the document is paper-based or digital.
• This listing represents a withdrawn edition, so the description should be read as the technical subject of that edition rather than an active compliance claim.
