TS EN 13232-1

TS EN 13232-1 defines the terminology used for railway switches and crossings in track applications. It provides the common language for naming the parts of these track arrangements and for understanding how the components relate to each other. Although this edition is withdrawn, the subject remains a fundamental part of railway engineering because switches and crossings are the elements that allow trains to diverge, merge, or pass through intersecting track geometry.

Why switches and crossings need precise definitions

In general technical terms, a switch guides a vehicle from one route to another, while crossings are the special rail arrangements that let wheelsets pass through a geometric intersection or branch arrangement. These systems combine several interacting components, such as switch rails, crossing noses, check rails, and associated assemblies. Clear terminology matters because similar-looking parts can have different roles, and misunderstandings can affect design communication, manufacture, inspection, and maintenance.

What this part contributes as a vocabulary standard

• Establishes shared meanings for the basic terms used in switches and crossings.
• Supports consistent naming of components and subassemblies.
• Helps technical drawings, specifications, and maintenance records use the same concepts in the same way.
• Reduces ambiguity in railway engineering communication across design, production, and operations.

This part is best understood as a terminology framework rather than a product-performance document. It is useful wherever professionals need to describe the geometry and functional elements of switch and crossing systems with precision. Because the standard is withdrawn, it should be treated as historical technical reference rather than an assurance of current practice or current conformity requirements.
