TS 12605

TS 12605 is a guide for the consistent use of terminology in railway applications, with emphasis on the terms used in railway operations and in related European Standards. Based on the title and scope, this document is not presented as a test method standard; instead, it serves as a terminology harmonisation guide for technical communication, procurement language and the interpretation of established railway standards.

How terminology support works in railway practice

In railway engineering, terminology helps align communication across operations, traffic management, maintenance, rolling stock and infrastructure. Where public bodies or users procure railway-related goods or services, consistent wording reduces the risk of misunderstanding technical requirements. The general role of this standard is to harmonise various terms used in European Standards so that the same concept is expressed in a more uniform and dependable way.

What this guide does and does not cover

This document is centred on terminology use in the context of railway operations, so its value lies in conceptual consistency rather than in specifying equipment performance limits or detailed procedures. Clear terminology supports contracts, specifications and technical correspondence by helping preserve the intended meaning of terms across documents. In broader railway practice, terminology harmonisation is an important part of the technical framework that supports safe, coordinated and interoperable systems.
