TS EN 15380-2

TS EN 15380-2 is the second part of the designation system for railway vehicles, focused on how product groups are organised within a short-designation structure. It supports a product-oriented way of structuring a railway vehicle or subsystem so that design, manufacturing, and supply-chain teams can work with a common technical language.

What the product-group approach is meant to do

In railway projects, the same component can be described differently by different disciplines. A product-group structure helps define parts in a hierarchical and understandable way, while also taking account of so-called combined assemblies whose functions may overlap. This is particularly useful when a platform, subsystem, assembly, and supplier network all need to refer to the same technical object consistently.

Technical context and practical meaning

From a general technical documentation perspective, such a designation system provides a shared reference for product breakdown, configuration management, and communication. In railway vehicles, groups such as bogies, braking equipment, doors, interior fittings, or power systems can be identified across different levels of detail within the same project. The standard’s focus is therefore on expressing product structure in a common language rather than defining the detailed design rules for each individual part.

• Supports product-oriented structuring for railway vehicles.
• Accounts for combined assemblies with overlapping functions.
• Provides a common communication basis for customers, suppliers, subcontractors, and other parties.
• Covers the product-group portion of the short-designation system.
