Overview

SIST EN 15461:2008/kFprA1:2010 is a European Standard developed by CEN that addresses railway noise emission with a focus on the dynamic characterization of track sections. This standard specifies a consistent and reliable method for assessing the dynamic behavior of railway track structures to understand their contribution to rolling noise during pass-by noise measurements. It plays a critical role in ensuring accurate noise emission data for railway applications, thereby supporting noise mitigation strategies and regulatory compliance.

The amendment FprA1 aligns this standard with the EU Directive 2008/57/EC on rail system interoperability, ensuring that noise emission parameters conform to updated European requirements. This standard is essential for stakeholders involved in railway infrastructure, rolling stock manufacturers, and environmental compliance authorities.

Key Topics

• Dynamic Properties of Track Structures
  The standard defines procedures to characterize the dynamic response of track sections, including their vibration and sound radiation behavior, which directly impacts rolling noise emissions.

• Pass-by Noise Measurement
  It establishes measurement conditions and reference track criteria to ensure consistency in pass-by noise testing, facilitating comparable and reliable noise emission results.

• Environmental Noise Protection
  By accurately describing track dynamics, the standard supports noise control initiatives, aiding in the design and maintenance of railway infrastructure that complies with environmental noise limits.

• Relationship to EU Directive 2008/57/EC
  Included annexes explain how adherence to EN 15461 confers presumption of conformity with the essential requirements of the EU Directive related to railway interoperability and noise emission limits.

• Harmonization with ISO Standards
  EN 15461 refers to deviations and complements EN ISO 3095:2005, the international standard for rail noise measurement, ensuring alignment with globally recognized methodologies.

Applications

• Rail Infrastructure Design and Maintenance
  Engineers and planners can utilize this standard to assess and enhance track designs that minimize noise emissions, ensuring quieter railway corridors.

• Rolling Stock Noise Certification
  Manufacturers use dynamic track characterization data to evaluate rolling noise contributions during vehicle certification, especially for high-speed and conventional rail stock.

• Environmental Compliance and Regulation
  Regulatory bodies apply measurement methods defined by EN 15461 to verify noise emission limits, enforce regulations, and monitor railway noise pollution levels.

• Research and Development
  Researchers studying railway noise and vibration phenomena benefit from standardized methods to characterize track-induced noise, supporting innovation in noise reduction technologies.

• Interoperability Assessments
  The standard aids interoperability assessments within the European rail network by ensuring consistent noise measurement approaches aligned with EU legislation.

Related Standards

• EN ISO 3095:2005 - Acoustics - Railway Applications - Measurement of Noise Emitted by Rolling Stock
  Provides the foundation for noise measurement methods that EN 15461 complements by focusing on reference track dynamic properties.

• EU Directive 2008/57/EC - Interoperability of the Rail System Within the Community
  The overarching European legislative framework that governs rail system standards, including noise emission requirements referenced in EN 15461.

• EN 15610 - Railway Applications - Noise Emission - Railways: Measurement Methodology
  Addresses broader methodologies for rail noise testing and can be used in conjunction with EN 15461 for comprehensive noise evaluation.

• CEN/TC 256 Standards related to Railway Noise and Vibration
  A collection of European standards managed by the same technical committee addressing diverse aspects of railway noise control.
