Overview
EN 16727-1:2018 - "Railway applications - Track - Noise barriers and related devices acting on airborne sound propagation - Non‑acoustic performance - Part 1: Mechanical performance under static loadings" (CEN) defines verification methods, calculation rules and test procedures to assess the mechanical performance and stability of railway noise barriers under static load conditions. The standard applies to barriers built from posts (structural elements) and panels (acoustic elements) - including metal, timber, plastic or concrete panels - and to acoustic claddings and partial/total track coverings. It requires that acoustic and structural elements are tested together to represent the barrier as intended in use.
Key topics and requirements
- Scope and applicability
- Covers noise barriers composed of posts and panels and acoustic claddings of existing walls or track coverings.
- Evaluation under standard exposure conditions irrespective of materials used.
- Design basis
- Verification follows EN 1990 (Eurocode - Basis of structural design) and related Eurocodes for actions and materials.
- Segment-based assessment where construction, geotechnical conditions and loads are constant.
- Loads and actions considered
- Permanent loads (self‑weight), variable loads (wind/air pressure), snow, impact loads (e.g., debris), and actions from snow‑clearing equipment.
- Static assessment only - dynamic train-induced loads are addressed in EN 16727 Part 2 series.
- Methods of verification
- Calculation, material testing, full‑scale testing, or a combination.
- Verification against Serviceability Limit State (SLS) and Ultimate Limit State (ULS).
- Design assumptions
- Design temperature range: −30 °C to +70 °C.
- Design working life: Category 3 or higher per EN 1990.
- Reporting
- Requires evaluation reports, test reports and static calculation reports.
- Annexes
- Includes informative correction factors for added devices (e.g., T‑tops).
Practical applications and users
Who uses EN 16727-1:2018:
- Railway infrastructure designers and structural engineers (noise barrier design and verification)
