Overview

EN 13481-1:2012 (CEN) provides the authoritative definitions used across the EN 13146 test methods and the EN 13481 performance requirements series for railway track fastening systems. By standardizing terminology for components, system categories and mechanical properties, this part supports uniform specification, testing, procurement and maintenance of rail fastenings for both ballasted and slab track applications.

The standard clarifies key vocabulary such as fastening system types, component names (baseplate, rail pad), system categories (A–E), and mechanical parameters including clamping force, static and dynamic stiffness, and transfer stiffness.

Key Topics

• Categories of fastening system (A–E): defined by typical axle load, curve radius, maximum speed and typical rail section and support spacing. Categories help match fastening selection to operational conditions (urban light rail through heavy freight lines).
• Track types: distinctions between ballasted track and slab track, and the definition of embedded rail (rail contained in a channel, with flange way maintained and secured by surrounding material or mechanical fixings).
• Component definitions: clear names and roles for baseplate, baseplate pad, rail pad, anti-creep rail pad, running rail, check rail, guard rail, sleeper and bearer.
• Mechanical properties and measurements:
  • Clamping force: vertical force applied by clips to the rail foot.
  • Static stiffness and vertical stiffness: force per unit deflection under static or vertical loads.
  • Dynamic stiffness: frequency-dependent stiffness measured for cyclic uniaxial forces; split into low frequency (3–30 Hz) and high frequency (20–450 Hz) ranges as defined in the standard.
  • Transfer stiffness: ratio of force on blocked output to input displacement during harmonic vibration (25–400 Hz).
• Vibration and noise terms: vibration attenuation and noise attenuation definitions relate to transmission or emission reductions from running rails into the supporting structure and surroundings.

Applications

EN 13481-1:2012 is essential for professionals involved in:

• Specification and procurement of fastening systems to ensure compatibility with performance tests and operational requirements.
• Test laboratories and manufacturers using EN 13146 test methods to validate system performance against common definitions.
• Track designers and asset managers selecting fastenings for ballasted or slab track, embedded rail installations, switches and crossings.
• Maintenance planners interpreting test results (clamping force, stiffness, attenuation) to make evidence-based renewal or adjustment decisions.

By harmonizing terminology, the standard reduces ambiguity, improves interoperability across suppliers and authorities, and supports safety, durability and predictable track behavior.

Related Standards

• EN 13146 series - Test methods for fastening systems (Parts 1–9)
• EN 13481 series - Performance requirements (Parts 1, 2, 3, 4, 5, 7)
• EN 13674 series - Rail sections referenced in category notes
• EN 13848-1 - Track geometry quality (used as source for running surface definition)

These referenced documents define test procedures, rail types and related track geometry terminology that work together with EN 13481-1:2012 to form a coherent framework for fastening system performance and verification.
