applications”, the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
Introduction
Platform barrier systems provide a moveable barrier between trains and other guided transit vehicles,
and passengers waiting at stations and boarding points.
Platform barrier systems are used increasingly on metro and other rail networks to ensure the safety of
passengers on the station platform who are waiting to board vehicles. Such systems are also used on
‘people-mover’ guided systems for short-distance transits, for example at airports. Their use is
recommended by IEC 62267 for any fully automated transit system.
In particular platform barrier systems can be used to control the risks of:
— incursion by passengers or other persons on the railway track (deliberate or accidental);
— contact between passengers and moving vehicles.
These risks can be especially significant where there is the possibility of overcrowding on station
platforms at busy locations. Barriers can in fact increase the safely useable space in the station for
passengers waiting and circulating on the platforms.
Platform barrier systems integrate the operation of the platform barrier doors and gates with opening
and closing of train doors and also assist in the management of station operations, to safely permit
higher entry and exit speeds for trains serving the stations.
Barrier installations can also be part of a continuous partition between the running tracks and the
station areas for the purposes of:
— fire safety (including smoke management);
— tunnel and station ventilation;
— trackside noise reduction;
— passenger comfort at climate controlled stations.
Additionally the terminology used in connection with platform barrier systems; in particular to improve
the specification and understanding of safety requirements, should be standardized.

4 System design requirements
4.1 Physical and structural requirements of the platform barrier
4.1.1 General structural requirements
4.1.1.1 Platform barrier systems form a safety barrier separating customers/passengers from
moving trains until it is safe to grant access. As such they shall be designed to resist crowd loading.
Platform barriers are also subject to aerodynamic loads induced by trains passing the structure.
Platform barrier systems installed in open sections shall also resist wind loading. In addition, platform
barrier systems might be subject to pressures generated by tunnel ventilation systems and might be
required to resist earthquakes. These separate actions shall be combined in accordance with Structural
Eurocodes referenced from this standard.
4.1.1.2 Tunnel ventilation systems are normally associated with platform door systems that
completely enclose the platform area separating it from the track on which vehicles move. Detailed
modelling/simulation shall be undertaken during system integration and shall consider all operating
and degraded modes of operation of the ventilation system to determine their effect on the platform
door system and how they combine with the aerodynamic actions from trains. In particular, pressures
generated by operation of ventilation systems for smoke extract or fire management shall not inhibit
operation of emergency doors in accordance with 4.1.7.
4.1.1.3 Structural design shall take account of the requirements arising from the physical interface
with trains intended to operate in conjunction with the barrier system, in particular regarding
entrapment (4.1.10) and gauging (5.2.3).
4.1.1.4 General construction of platform barriers shall be in accordance with the Structural
Eurocode series. EN 1991-1-1 covers general actions and imposed loads. Imposed loads are defined by
categories of use is Clause 6. This series of standards explicitly includes barriers on railway platforms,
in particular Category C5 which gives requirements for ‘Areas susceptible to large crowds, e.g. in
building for public events like concert hall, sports halls including stands, terraces and access areas and
railway platforms.’
4.1.1.5 The Structural Eurocode series of standards mandate the use of Ultimate and Serviceability
Limit States to ensure safety of the structure in extreme conditions (e.g. storm-force winds for open-air
systems) and combinations of loads; however, normal operation of the platform doors/gates might not
be practicable under all such limit states. At least one Operational Limit State should be specified to
reflect normal operation of the barrier system. Further guidance is given in Annex B.
4.1.1.6 Deflection of the platform barrier system towards the track under any loading conditions
envisaged in this standard shall not exceed the limits defined by the gauging strategy for the platform
barrier system as described in 5.2.3. Plastic deformation may be permitted under Ultimate Limit State
as defined by the Eurocodes referenced in Annex B, subject to compliance with the gauging strategy.
4.1.1.7 Infill panels (i.e. glazing, or sheets of other materials, which separate the platform area from
the running tracks and are secured to the main structural framework of the barrier system) shall
sustain the applied loads. In addition, deflection of an infill panel that is structurally safe should not
alarm station users through large visible deformations when subject to normal service conditions.
Therefore, for serviceability considerations, the limiting condition for deflection is that the total
horizontal displacement of the infill panel at any point from its original unloaded position shall not
exceed the deflection limits determined from the relevant structural design code (where applicable) for
the material used or 25 mm, whichever is the smaller.
4.1.1.8 This standard covers the requirements for the platform barrier system. It does not specify
requirements for the platforms, or other foundations and structures to which the platform barrier
system is secured. Design and construction of platforms, foundations or other structures are covered by
other appropriate structural Eurocode documents. However, the load cases considered in such designs
shall be consistent with those adopted for the design of the platform barrier system.
4.1.2 Structural design principles
4.1.2.1 Designs shall be in accordance with the requirements of EN 1990.
4.1.2.2 Where steel is used, structural design shall be in accordance with EN 1993-1-1.
4.1.2.3 Where aluminium is used, structural design shall be in accordance with EN 1999-1-1.
4.1.2.4 In the event that structural materials other than steel or aluminium are used, performance
of the design shall be demonstrated to be equivalent with the performance requirements of Eurocodes
category C5 as defined in 4.1.1.4.
4.1.2.5 Where required by the relevant National Annex to EN 1998-1 regarding design of structures
for earthquake resistance, the provisions of EN 1998-1 shall be applied in addition to the provisions of
the other relevant Eurocodes.
4.1.2.6 Where glass is used the thickness of the glazing material may be calculated using finite
element analysis. Alternatively thickness may be determined using empirical national codes but this can
result in conservative design and increased weight.
4.1.3 Structural loading conditions
4.1.3.1 Crowd loading
4.1.3.1.1 Design for horizontal crowd loading shall be in accordance with EN 1991-1-1:2002, 6.4. The
characteristic value for the line load q as defined in the standard shall be selected from the range for
k
Category C5 from Table 6.12.
4.1.3.1.2 The design value for crowd loading shall correspond to the minimum value defined in
EN 1991-1-1:2002 category C5 from Table 6.12. A higher value shall only be considered when a site
specific risk assessment confirms a greater value is required. The structural design shall not be
specified beyond what is essential in foreseeable conditions, since such ‘over-design’ can result in
increased volume and mass of moving and other parts with disadvantages for gauging and for safe and
efficient motion of doors and gates.
4.1.3.2 Aerodynamic loading from trains
4.1.3.2.1 Aerodynamic loads arising from the movement of trains alongside platform barrier systems
that completely enclose the platform area shall be considered in the structural design of the barrier. In
such case the platform area is completely separated from the track on which vehicles move (e.g. where
separation is designed to support operation of a tunnel ventilation system, or climate control of the
station). Such systems shall be fully analysed in accordance with the requirements of 4.1.1.2.
4.1.3.2.2 Aerodynamic loads arising from the movement of trains alongside barrier systems that do
not fully enclose the platform area shall be considered in the structural design of the barrier system. In
such cases design loads may be calculated in accordance with the methodology in Annex E, or be based
on empirical measurement of comparable train and barrier combinations.
4.1.3.2.3 When assessing the mechanical and fatigue strength requirements of the barrier structure,
the aerodynamic actions can be assumed to be of an equivalent amplitude at the front and back of the
train and, in the case of coupled train units, also at the inter-unit coupler. This amplitude shall be taken
to be the largest of the actions generated during the complete time of passing of the train.
4.1.3.2.4 Since aerodynamic loading occurs every time the train passes a barrier, the loads calculated
in accordance with 4.1.3.2.1 or 4.1.3.2.2 shall be considered as fatigue loads as required by 4.1.3.4.2 of
this standard.
4.1.3.3 Wind loading
Wind loading shall be considered in accordance with EN 1991-1-4 (including associated National
Annexes).
4.1.3.4 Fatigue
4.1.3.4.1 Structural fatigue performance shall satisfy the required safety and performance for the
design life of the installation. In particular, design against structural fatigue failure for steel and
aluminium elements shall be assessed in accordance with the following standards (including their
associated National Annexes):
• EN 1993-1-9 (for steel);
• EN 1999-1-3 (for aluminium).
4.1.3.4.2 The fatigue effects of aerodynamic loading from passing trains shall be considered for all
platform barrier systems as specified in 4.1.3.2.4.
4.1.3.4.3 If relevant, the fatigue effects of wind loading shall be considered for platform barrier
systems installed in open-air sections, taking account of established meteorological conditions as
determined in compliance with 4.1.11.1.
4.1.3.4.4 Crowd loading shall not be considered to be cyclical for the purposes of assessing the fatigue
life of the platform barrier system.
4.1.4 Glazing and other panelling materials in facades, including doors and gates
4.1.4.1 General principle
There is no normative requirement to make the fixed part of the facades, or doors and gates, fully or
partly transparent, but where glazing materials are used, the requirements of 4.1.4.2 shall be applied.
Where partial transparency is achieved through use of mesh or perforated material the requirements of
4.1.4.3 shall be applied.
4.1.4.2 Requirements for glazing materials
4.1.4.2.1 Where glass is used as a panelling material, it shall be of a type that does not fracture in a
way that creates hazard to passengers. In particular the glass shall only fail with Type B breakage as
defined in EN 12600.
4.1.4.2.2 The glazing shall not readily fail in a way that creates an aperture in the barrier that
passengers can reach through and be exposed to hazard from moving trains.
4.1.4.2.3 Where laminated glass is used it shall be in accordance with EN ISO 12543-1.
4.1.4.2.4 Glazing used shall achieve level 1-B-1 in accordance with the quantification tests given in
EN 12600. The test described in EN 12600 is primarily designed for laminated glass; however where
other types of glass are used they shall achieve an equivalent level of safety in respect of the
requirements in 4.1.4.2.1 and 4.1.4.2.2.
4.1.4.2.5 Alternative glazing materials (e.g. polycarbonate materials) shall as a minimum fulfil the
same requirements as glass in respect of impact resistance, and shall meet the general requirements for
penetration, deflection under load, and fire and smoke performance defined in the relevant sections in
this standard.
4.1.4.2.6 Where glazing is fully transparent and extends to the full height of the doorway, strips or
patterns of non-transparent material or finish shall be added to the glazing to reduce the possibility of
accidental contact by passengers.
4.1.4.3 Mesh, perforated and other materials
4.1.4.3.1 Where panels made from mesh or perforated material are used the edges of the meshes or
perforations shall not have sharp edges or projections likely to cause injury.
4.1.4.3.2 It shall not be possible for any person from the user population to pass any part of their
hand through the mesh or perforation of a panel such that they might be injured by opening or closing
of a door/gate, or by the movement of a train.
4.1.4.3.3 Mesh or perforated panels shall meet the general requirements relating to fire and smoke
performance, deflection under load and impact resistance defined in the relevant sections in this
standard.
4.1.4.3.4 Mesh or perforated materials shall not be used for moving panels because of the increased
risk of finger trapping or of clothing etc. being drawn into door/or gate systems.
4.1.4.3.5 Any other materials used as panelling in any part of the facade shall meet the general
requirements relating to fire and smoke performance and deflection under load, defined in the relevant
sections in this standard. The materials shall also meet the intent of requirements of 4.1.4.2.1 and
4.1.4.2.2 regarding fracture and response to impact.
4.1.5 Fire performance - use as a fire barrier
Full height platform barriers at sub-surface or enclosed stations may be used as a direct fire barrier, to
minimize the spread of smoke in the event of a fire on either side of the barrier, or simply to segregate
ventilation in the station and track areas. If a platform barrier system is intended to be used as a fire
barrier, requirements of this standard are still applicable, but in that case such a barrier shall also
conform to additional and relevant fire standards or national rules outside the scope of this standard.
4.1.6 Fire performance - fire resistance of materials
4.1.6.1 Materials used shall have fire resistance properties in accordance with national rules and
European and national building codes. Components shall be defined and selected in accordance with the
requirements of EN 13501-1, EN 13501-2 and EN 13501-6.
NOTE There might be specific national and European rules for materials used in underground and tunnel
environments (including, where the station falls within its scope, the Safety in Rail Tunnels Technical Specification
for Interoperability).
4.1.6.2 The material used in the interlayer of laminated glass shall not be considered as
contributing to a fire load unless specifically required by local regulations, provided that the laminated
glass is fully compliant to all other relevant standards in accordance with 4.1.4.2 of this document.
4.1.7 Requirements for emergency doors/gates
4.1.7.1 It shall be possible for passengers to evacuate in an emergency from a train or vehicle at a
station fitted with platform barriers, even if the train has stopped such that train doors and platform
doors/gates are not in correct alignment.
4.1.7.2 The entity within a project that is responsible for system integration shall make a quantified
risk assessment for each platform barrier installation to decide whether, and to what extent, emergency
doors/gates shall be included in the design to ensure that the above objective is achieved. Factors for
consideration shall include as a minimum:
• the total number of passengers who might need to make an emergency evacuation from a train;
• the possibility of safe emergency egress from the non-platform side of the train;
• the total number and width of doors/gates provided for normal use;
• the probability that a train might be immobilised in a way that vehicles are completely misaligned
with the normal doors/gates;
• the capability of the driver and/or train control system to move the train a short distance to achieve
correct alignment;
• needs for evacuation of wheelchair users and other persons of restricted mobility.
4.1.7.3 The risk assessment shall be made at railway system level, taking into consideration the
overall safety risk factors (e.g. whether the installation is at a sub-surface station, fire control measures,
level of system automation etc.).
4.1.7.4 Where emergency doors/gates are provided they shall meet the relevant requirements of
EN 1125 regarding release and operating forces. The release mechanism shall be accessible from an
open doorway of an adjacent vehicle.
4.1.7.5 Where emergency doors/gates are provided they shall meet the minimum strength and
other structural requirements as necessary for all other panels and doors/gates in the barrier system in
accordance with 4.1.1.6.
4.1.7.6 Where provided, emergenc
