TS EN 14478

TS EN 14478 is a generic vocabulary standard for railway braking. Its purpose is to harmonize the common terms and definitions used for brakes and braking in rolling stock, so that manufacturers, operators, maintenance teams and technical documentation use the same concepts in the same way.

Where braking terminology fits in railway engineering

In railway practice, braking covers the systems that reduce speed, bring a vehicle to a stop and, when needed, keep it stationary. In general technical context, this is a multi-system field where mechanical, pneumatic, electric and electronic elements may work together. Clear definitions of core terms such as “brake” and “braking” improve consistency across multiple types of rolling stock and reduce ambiguity in engineering communication.

What the standard covers

• It provides terms and definitions for common use relating to brakes and braking in rolling stock.
• It supports consistent use of braking concepts in railway engineering terminology.
• It is useful for design, maintenance, operation and documentation where a shared technical language matters.
• It should be understood as a vocabulary standard, not as a document that sets vehicle-specific performance limits or test conditions.

In broader terms, railway braking may involve friction braking, regenerative braking and emergency braking, among other principles; however, this listing is about standardizing the language of the subject rather than defining the performance of a particular braking technology. As such, TS EN 14478 provides a dependable common reference for technical reports, specifications, training materials and system descriptions.
