TS 12740-1

TS 12740-1 is a terminology standard for the general terms used for parts in railway vehicles. Because railway vehicles contain many mechanical, structural, and auxiliary components, a shared vocabulary helps avoid ambiguity and supports consistent technical communication across design, maintenance, and documentation work.

What this railway vehicle terminology covers

This standard covers general names for the parts used in railway vehicles. Terminology standards define how concepts are named rather than how products are manufactured or tested. In that sense, TS 12740-1 serves as a reference for consistent wording in technical drawings, manuals, catalogues, training material, and engineering correspondence.

In general technical context, railway vehicles include many interconnected systems such as the body, bogies, wheelsets, braking equipment, doors, fasteners, and auxiliary equipment. Clear terminology helps distinguish the function of each part and reduces misunderstanding when the same component may otherwise be described in different ways.

• Creates a common vocabulary for general terms related to parts used in railway vehicles.
• Focuses on naming concepts rather than prescribing a manufacturing or test method.
• Supports terminology consistency in maintenance, repair, design, and documentation.
• Acts as a general reference for railway engineering terminology.
