SIST EN 13775-6:2004

Overview

EN 13775-6:2004 - Railway applications: Measuring of new and modified freight wagons - Part 6: Multiple and articulated freight wagons is a CEN European Standard that defines the principles and requirements for measuring multiple and articulated freight wagons. The standard establishes uniform criteria for measurement processes to ensure consistency when assessing the geometry and dimensions of new builds and modified wagons. It applies to whole wagons or to parts of wagons where the geometrical structure prevents full‑unit measurement. The standard also covers wagons with or without add‑ons; where measurement needs fall outside the document’s scope, specific procedures are agreed between contracting parties.

Key Topics

• Scope and applicability: Measurement of new and modified multiple and articulated freight wagons, including wagons with add‑ons and situations where only part measurement is possible.
• Principles for measuring: Uniform criteria and high‑level requirements that ensure repeatable, comparable measurement results across projects and stakeholders.
• Measurement processes: Guidance on applying appropriate measuring processes; recognizes that additional, case-specific methods may be necessary.
• Contracting‑party agreements: Provisions that go beyond the standard’s baseline must be explicitly agreed between the contracting parties.
• Interoperability and geometry considerations: Ensures dimensions and geometric data support safe operation, compatibility and integration in multi‑vehicle consists.

Applications

• Design verification and approval of new multiple or articulated freight wagons.
• Assessment after modifications, repairs or retrofits to confirm compliance with agreed geometry.
• Acceptance testing during manufacturing and commissioning.
• Clearance and compatibility checks for wagon combinations, loading gauges and coupling interfaces.
• Production of reliable as‑built geometric data for maintenance records, asset management and regulatory compliance.

Who uses this standard?

• Wagon manufacturers and engineering teams performing design and verification.
• Railway operators and freight carriers validating fleet modifications.
• Maintenance organizations and workshops conducting post‑repair measurement checks.
• Notified bodies, certification and testing laboratories involved in conformity assessment.
• Engineering consultants and system integrators responsible for interoperability and vehicle combinations.

Related standards

• Other parts of the EN 13775 series and related CEN/railway standards cover measuring requirements for different wagon types and testing methods. Where the standard’s provisions are not sufficient, supplementary measurement procedures are specified case‑by‑case between contracting parties.

This standard is a practical reference for consistent, repeatable measurement procedures that support safe operation, interoperability and quality assurance in the railway freight sector.
