Railway applications - Infrastructure- Noise barriers and related devices acting on airborne sound propagation - Non-acoustic performance - Part 2-1: Mechanical performance under dynamic loadings due to passing trains - Resistance to fatigue

This document describes the basic requirements for the verification of ultimate and serviceability limit states and the resistance to fatigue either of the noise barrier or its components by means of analytical methods and/or tests.
Analytical methods can be used for the determination of the characteristic values and design values.
Where sufficient information is not available, the analytical procedure can be combined with results from tests.
This document provides the following types of test procedures:
- test on small samples for defining detail categories, which might not be covered by Eurocodes (verification procedure A);
- test on a global element for defining the limit state against fatigue (verification procedure B);
- full scale tests under a given representative loading (verification procedure C) to determine fatigue resistance of the noise barrier components for defined loading conditions; verification procedure C is given as alternative to verification procedures A and B.

European foreword
This document (prEN 16727-2-1:2025) has been prepared by Technical Committee CEN/TC 256
“Railway Applications”, the secretariat of which is held by DIN.
This document is currently submitted to CEN enquiry.
This document will supersede EN 16727-2-1:2018.
This document is one of the series EN 16727, Railway applications — Track — Noise barriers and related
devices acting on airborne sound propagation — Non-acoustic performance, as listed below:
— Part 1: Mechanical performance under static loadings — Calculation and test method;
— Part 2-1: Mechanical performance under dynamic loadings due to passing trains — Resistance to
fatigue [this document];
— Part 2-2: Mechanical performance under dynamic loadings caused by passing trains — Calculation
method;
— Part 3: General safety and environmental requirements.
It is intended to be read in conjunction with:
— EN 16727-1, Railway applications — Track — Noise barriers and related devices acting on airborne
sound propagation — Non-acoustic performance — Part 1: Mechanical performance under static
loadings — Calculation and test method;
— EN 16727-2-2, Railway applications — Track — Noise barriers and related devices acting on airborne
sound propagation — Non-acoustic performance — Part 2-2: Mechanical performance under dynamic
loadings caused by passing trains — Calculation method.
Introduction
Passing trains generate an air pressure wave, which impacts noise barriers installed alongside the track.
It is important that noise barriers withstand this impact without any part of them becoming detached or
displaced in an unsafe manner; they should be designed for the specified requirements in ultimate,
serviceability and fatigue limit states. Where no design rules or sufficient experience with components
are available, the design should be based on calculation and/or tests carried out in a way that provides
information on the properties of the component for design in ultimate and serviceability limit states and
the resistance to fatigue. This document applies to noise barrier components or to noise barriers
considered as a whole.
1 Scope
This document describes the basic requirements for the verification of ultimate and serviceability limit
states and the resistance to fatigue either of the noise barrier or its components by means of analytical
methods and/or tests.
Analytical methods can be used for the determination of the characteristic values and design values.
Where sufficient information is not available, the analytical procedure can be combined with results from
tests.
This document provides the following types of test procedures:
— test on small samples for defining detail categories, which might not be covered by Eurocodes
(verification procedure A);
— test on a global element for defining the limit state against fatigue (verification procedure B);
— full scale tests under a given representative loading (verification procedure C) to determine fatigue
resistance of the noise barrier components for defined loading conditions; verification procedure C
is given as alternative to verification procedures A and B.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminology databases for use in standardization at the following addresses:
• ISO Online browsing platform: available at https://www.iso.org/obp
• IEC Electropedia: available at https://www.electropedia.org/
3.1
noise barrier
noise reducing device, which obstructs the direct transmission of airborne sound emanating from
railways, and which will typically span between posts and also may overhang the railway
Note 1 to entry: Noise barriers are generally made of acoustic and structural elements (3.3 and 3.4).
3.2
cladding
noise reducing device, which is attached to a wall or other structure and reduces the amount of sound
reflected
Note 1 to entry: Claddings are generally made of acoustic and structural elements (3.3 and 3.4).
3.3
acoustic element
element whose primary function is to provide the acoustic performance of the device
3.4
structural element
element whose primary function is to support or hold in place acoustic elements
Note 1 to entry: In some noise barriers, the acoustic function and the structural function cannot be clearly
separated and attributed to different components.
3.5
added device
added component that influences the acoustic performance of the original noise-reducing device (acting
primarily on the diffracted energy)
Note 1 to entry: In some noise barriers, the acoustic function and the structural function cannot be clearly
separated and attributed to different components.
3.6
representative loading
loading which takes into account the load effects caused by the air pressure wave of the train, the site-
dependent parameters, the dynamic amplification factor and the fatigue stress behaviour of the
component, including the fatigue damage accumulation
Note 1 to entry: Examples of site-dependent parameters are: the design life, the number of trains per day, the
maximum train speed, the spacing between the noise barrier and the rail track.
