European foreword
This document (EN 15153-2:2020) has been prepared by Technical Committee CEN/TC 256 “Railway
applications”, the secretariat of which is held by DIN.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by July 2020, and conflicting national standards shall be
withdrawn at the latest by July 2020.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 15153-2:2013.
The main changes with respect to the previous edition are:
— a new frequency option (c) in 5.2.1;
— clarification of the test site requirements (Figure 1) in 6.1;
— addition of Annex A (list of contractual agreements);
— revision of Annex ZA.
This series of documents Railway applications — External visible and audible warning devices consists of
the following parts:
— Part 1: Head, marker and tail lamps for heavy rail;
— Part 2: Warning horns for heavy rail (this document);
— Part 3: Visible warning devices for urban rail;
— Part 4: Audible warning devices for urban rail.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports essential requirements of EU Directive 2016/797/EC.
For relationship with EU Directive 2016/797/EC, see informative Annex ZA, which is an integral part of
this document.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland,
Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of
North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the
United Kingdom.
Introduction
This document was produced following the creation of EN 15153-4 for urban rail vehicles.
This document was re-named to make a clear distinction between heavy rail and urban rail.
Additionally, Annex ZA was updated for the current status of TSIs.
1 Scope
This document defines warning horn requirements that deliver the required audibility of approaching
heavy rail vehicles. The requirements of this document do not apply to urban rail systems.
NOTE 1 The requirements for exterior audible warning devices for urban rail vehicles are found in EN 15153-4.
In the case of shunting heavy rail vehicle formations, the requirements of this document do not apply to
the pushed vehicle(s).
For this purpose, the following requirements are included:
— functional and technical requirements of the warning horn as a component,
— functional and technical requirements of the integration of warning horns into the vehicle, and
— test requirements.
Operational requirements and maintenance requirements for warning horns are excluded.
NOTE 2 The requirements for the control of warning horns can be found in EN 16186-2.
2 Normative references

constitutes requirements of this document. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments) applies.

5 Requirements
5.1 General
Trains shall be fitted with one or more warning horns on the leading vehicle.
All vehicle fronts shall be fitted with warning horn(s).
In the case of shunting locomotives only, the requirements of this document may be satisfied by a single
omni-directional warning horn.
Consideration shall be given to the location of the warning horns, taking into account the possible
exposure of staff to excessive noise.
NOTE The aim is to control the risk of accidental hearing damage when a horn is sounded at a time when a
person is working close to the horn.
The limitation of noise exposure to persons inside the driver’s cab are addressed by respecting the limit
values for driver’s cab noise exposure as given in TSI Noise. In order to minimize environmental impact,
warning horns should be orientated along the longitudinal axis of the vehicle.
It is permissible for trains to be fitted with additional audible warning devices.
5.2 Acoustic requirements
5.2.1 Frequencies
The notes of the audible warning horns are intended to be recognizable as being from a train and not be
similar to warning devices used in road transport, factories or other common warning devices. The
warning horn frequencies shall be selected from the following options:
a) Two separately sounded warning horns. The fundamental frequencies of the warning horn notes
shall be:
— high note: 370 Hz ± 20 Hz;
— low note: 311 Hz ± 20 Hz.
b) Two separately sounded warning horns. The fundamental frequencies of the warning horn notes
shall be:
— high note: 660 Hz ± 30 Hz;
— low note: 370 Hz ± 20 Hz.
It is permissible for these horns to be sounded simultaneously.
