TS EN 15016-3

TS EN 15016-3 defines the basis for handling modifications to technical documents used in railway applications. In railway projects, even a small change to a drawing, model, or data file can affect design, manufacturing, installation, maintenance, and operation, so revision control is a core part of technical documentation practice.

What revision control means for technical documents

The focus of this standard is to provide a common basis for revising technical design documents. In general technical practice, revision control is the discipline that shows what has changed, which version is current, and how the history of a document remains traceable. For traditional drawings this may concern dimensions, geometry, notes, or references; for digital media it is equally about version management and data integrity.

Document forms and media in scope

• Transparency originals and plotter drawings
• Aperture cards as archived technical carriers
• Computer readable data media
• Photoprints and similar reproduced documents
• Any technical design documents used in railway applications

The scope makes clear that the standard is independent of the physical form of the document. Its concern is not whether the information is on paper, film, or digital media, but how the modification itself is managed. That approach supports a single reliable version of technical content across teams and disciplines, reducing the risk of mixing obsolete and current documents.

More broadly, this part supports document lifecycle control in the railway sector. Because it is built around the principles for revising technical documents, it helps organisations keep engineering information orderly, consistent, and traceable.
