NOTE Les systèmes ferroviaires urbains connaissent les mêmes situations, mais peuvent avoir d'autres écartements de voies individuelles. L’EN 16704-1 ne couvre pas les systèmes ferroviaires urbains. L'utilisation de barrières à titre de mesure de sécurité a le même objectif indépendamment du type de système ferroviaire.
La norme ne s’applique pas, en particulier, pour :
l’évaluation des risques pour la protection et la sécurité durant les travaux sur la voie ;
le classement des moyens de sécurité pour la protection et la sécurité durant les travaux sur la voie ;
les moyens de protection destinés à assurer la sécurité du travail et de la circulation des trains dans la zone du chantier ;
les réglementations nationales de sécurité pour organiser et utiliser les barrières en voie ;
les réglementations de sécurité et les exigences complémentaires, par exemple en raison de la réglementation nationale ou de règles organisationnelles ou de négociations entre l'utilisateur et le fabricant ;
les risques électriques dus à la différence de potentiel de différents circuits électriques.

EN 16704-2-2:2016 (E) 3 European foreword This document (EN 16704-2-2:2016) 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of an identical text or by endorsement, at the latest by May 2017, and conflicting national standards shall be withdrawn at the latest by May 2017. 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 has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. This European Standard is one of the series EN 16704 “Railway applications – Track – Safety protection on the track during work” as listed below: — Part 1: Railway risks and common principles for protection of fixed and mobile work sites — Part 2-1: Common solutions and technology – Technical requirements for Track Warning Systems (TWS) — Part 2-2: Common solutions and technology – Technical requirements for barriers — Part 3: Competences of personnel related to work on or near tracks 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, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

EN 16704-2-2:2016 (E) 4 Introduction The purpose of this standard is to define and harmonize requirements for barriers to separate working zone and danger zone and to prevent workers from entering the danger zone unintentionally. The purpose of this standard is not to define requirements: — for structural separation to provide safe train operation in the area of a work site(1); — for structural separation to provide safety on a work site during train operation(2). NOTE Examples for exclusions: (1) In case of crane operation on a work site the crane arm could hit or even intrude into the gauge of an open track and endanger the safety of train operation. (2) A barrier does not protect workers from items falling from passing trains. SIST EN 16704-2-2:2017
EN 16704-2-2:2016 (E) 5 1 Scope This European Standard deals with requirements for barriers to give users the possibility to prevent workers from entering the danger zone unintentionally by the use of such barriers. This standard defines minimum requirements and test procedures for these barriers concerning the dimensions, the stability and electrical properties. This standard also gives recommendations for the marking (visual demarcation line) where a person would enter the danger zone. For combinations of barriers and TWS see also EN 16704-2-1:2016. This standard contains references to electrical hazards from third rail systems. NOTE Urban rail systems do have the same situations but may have other individual track gauges. EN 16704–1 does not cover Urban rail systems. The use of barriers as a safety measure has the same intention independently of the kind of railway system. This standard in particular does not deal with: — risk assessment for safety protection on the track during work; — hierarchy of safety measure for safety protection on the track during work; — safety measure to provide safe working and safe train operation in the area of a work site; — national safety regulations to plan and operate barriers in track; — safety regulations and additional requirements e.g. due to national or operational rules or negotiation between the user and the manufacturer; — electrical hazards by different potential of different electrified circuits. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

All values (e.g. for height or distances) refer to straight horizontal tracks with a gauge of 1435 mm without rail cant. For other track gauges it is recommended to use Annex B to convert the distance in Figure 3 to other reference points. NOTE 1 For special situations (e.g. rail cant, 3rd rail) a risk assessment according to EN 16704–1:2016 may be required. As a result other and/or additional measures could be necessary. Barriers shall have no sharp or jagged edges. Barriers shall be usable on switches and crossings (e.g. by special attachment devices). Barriers shall be constructed in a way that the track circuit system is not affected and accidental electrical hazards are minimized (for details see 6.6). SIST EN 16704-2-2:2017
EN 16704-2-2:2016 (E) 10 It shall be possible to mount, position and remove all components easily and: — preferably from outside of the track, and — preferably without removing ballast or anti-vibration devices mounted to the rail. The various associated components shall allow quick assembly and disassembly. The construction shall allow during use: — temporary demounting of single modules; — variation of the distance to the track; — the removal of horizontal components without a tool in case of emergency. Components made of electrical non-conductive material shall have a length not exceeding 3,20 m. Components made of metal or other electrical conductive material shall have a length not exceeding 2,00 m. NOTE 2 In case of a maximum length of 3,20 m the distance from the track does change only in a range of f = 1 cm to 2 cm, even in small curves (R = 80 m) [f approximately length2/(8R)]. It shall be possible to adjust the length of a module in a range of 0,4 m minimum (e.g. by adjustable horizontal components or by variable fixing points for the horizontal components). 5.2 Horizontal components Principal and intermediate guardrails shall have a minimum cross-section height of 35 mm (see Figure 4). If intermediate guardrails are provided, any gap shall be so dimensioned that a sphere of 470 mm diameter will not pass through the protection. If there are no intermediate guardrails or if it is not continuous, the intermediate protection shall be so dimensioned that a sphere with a diameter of 250 mm will not pass through it. 5.3 Mounting of horizontal components at different transversal distances It shall be possible (e.g. by extendable devices) to position the horizontal components at transversal distances at least at 1,90 m, 2,00 m, 2,10 m, 2,20 m, 2,30 m, 2,40 m and 2,50 m (±20 mm) (see Figure 3) measured from centre of the track to the inner part of the barrier at the level of the horizontal components.

Each position of extendable devices shall be marked clearly. 5.5 Track gauge requirements Barriers including attachment devices shall respect the gauges of the track (for information see series of standards of EN 15273). For examples of vertical components see Figure 5. 5.6 Height Barriers shall prevent people from unintentionally entering into the danger zone. The height of the principal guardrail above the bottom of the rail (hmin) shall be at least 880 mm, but it is recommended to achieve a min. height hmin of 1000 mm as mentioned in EN 13374. The maximum height of components above the bottom of rail (hmax) shall be in accordance with Annex A (see also Figures 4 and 5) after preliminary loads according to 6.4.2.1.

Introduction
The purpose of this standard is to define and harmonize requirements for barriers to separate working
zone and danger zone and to prevent workers from entering the danger zone unintentionally.
The purpose of this standard is not to define requirements:
(1)
— for structural separation to provide safe train operation in the area of a work site ;
(2)
— for structural separation to provide safety on a work site during train operation .
NOTE Examples to found why to exclude the abovementioned purposes:
(1)
In case of crane operation on a work site the crane arm could hit or even
intrude into the gauge of an open track and endanger the safety of train
operation.
(2)
In case of a train derailment workers might be hit and get injured on the working
track or in the area nearby the work site by a derailed train or wagon.

1 Scope
This European Standard deals with requirements for barriers to give users the possibility to prevent
workers from entering the danger zone unintentionally by the use of such barriers.
This standard defines minimum requirements and test procedures for these barriers concerning the
dimensions, the stability and electrical properties.
This standard also gives recommendations for the marking (visual demarcation line) where a person
would enter the danger zone.
For combinations of barriers and TWS see also prEN 16704-2-1:2014.
This standard contains remarks for electrical hazards by a third rail.
This standard does not deal with:
— risk assessment for safety protection on the track during work;
— hierarchy of safety measure for safety protection on the track during work;
— safety measure to provide safe working and safe train operation in the area of a work site;
— national safety regulations to plan and operate barriers in track;
— safety regulations and additional requirements e.g. due to national or operational rules or
negotiation between the user and the manufacturer;
— electrical hazards by different potential of different electrified circuits.

Barriers shall comply with all requirements of clause 5 up to clause 8.
All values (e.g. for height or distances) refer to straight horizontal tracks with a gauge of 1435 mm
without cant.
NOTE For special situations (e.g. cant, 3rdrail) as a result of the risk assessment according to prEN 16704–
1:2014 other and/or additional measurement could be necessary.
Barriers shall have no sharp or jagged edges.
They should be usable on switches and crossings too, for example by special devices.
They shall be constructed in a way that the track circuit system is not influenced and accidental
electrical hazards are minimized (for details see sub-clause 6.6).
It shall be possible to mount, position and remove all components easily and:
— preferable from outside of the track, and
— preferable without removing ballast or anti-vibration devices mounted to the rail.
The various associated components shall allow quick assembly and disassembly.
The construction shall allow during use:
— temporary demounting of single modules;
— variation of the distance to the track;
— the evacuation in case of emergency. It should be possible to remove the horizontal components
without a tool. If this is not possible, the manufacturer shall give instructions for this case in the
manual.
Component made of non-conductive materials shall have a maximum length less than 3,2 m.
Components made of metal or other conductive material shall have a maximum length less than
2,0 m.
NOTE In case of a maximum length of 3,2 m the distance from the track does change only in a range of
2
f = 1 cm to 2 cm, even in small curves (R = 80 m) [f approximately length /8R].
It shall be possible to adjust the length of a module in a range of 0,4 m minimum (e.g. by adjustable
horizontal components or by variable fixation points for the horizontal components).
5.2 Horizontal components
Principal and intermediate guardrails shall have a minimum cross-section height of 35 mm (see
Figure 5).
If intermediate guardrails are provided, any gap shall be so dimensioned that a sphere of 470 mm
diameter will not pass through the protection. If there are no intermediate guardrails or if it is not
