Introduction
Platform barrier systems provide a movable 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 EN 62267 for any fully automated transit system.
In particular platform barrier systems can be used to control the risk of:
— incursion by passengers or other persons on the railway track (deliberate or accidental); and
— 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 may 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
speeds for trains entering and exiting 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 (including reduction of the piston effect);
— trackside noise reduction; and
— 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.
1 Scope
This document specifies requirements for the design, construction and operation of platform barrier
systems positioned at the edge of a station platform immediately adjacent to the rail or other guided
vehicles in stations and boarding points for passenger services. This document includes:
— requirements for the fixed structure and fixed parts along the platform;
— physical requirements for the movable doors and gates normally used by passengers;
— requirements for emergency doors;
— requirements for driver access doors;
— requirements for platform extremity doors; and
— requirements for the management of safety risks that are particular to barrier systems.
This document also gives requirements for the integration of barriers within the overall rail system,
including:
— synchronization of vehicle and platform barrier doors/gates;
— audible and visible alerts;
— integrity of control systems;
— testing of the barrier installation;
— operational performance; and
— requirements relating to other interfacing sub-systems, notably signalling and vehicles.
For barrier systems set back from the platform edge, which are used to control access to trains or for
crowd management, relevant sections of the document can be used as guidance.
This document applies to all persons involved in the implementation and system integration of a platform
barrier system, including infrastructure owners, designers, installers and operators.
This document does not cover barrier systems using bars, ropes, etc. or which operate in a vertical
direction.
This document applies to rail services, e.g. metro, tram systems and heavy rail services as requested by a
project specification. It applies to small systems, working in conjunction with a single vehicle, or with
larger systems working with a complete train.
This document applies to platform barrier systems used at sub-surface stations, enclosed surface stations
(e.g. those enclosed for the purposes of providing an air-conditioned environment for waiting
passengers), and those fully in the open-air.
This document does not cover normative requirements relating to fire performance or fire requirements
arising from use of platform barrier systems as fire barriers.

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 can be subject to pressures generated by tunnel ventilation systems and can be required to resist
earthquakes. These separate actions shall be combined in accordance with Structural Eurocodes
referenced in this standard.
4.1.1.2 Tunnel ventilation systems can be associated with platform barrier 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 barrier
system and how they combine with the aerodynamic actions from trains. In particular, pressures
generated by operation of ventilation systems for smoke extraction or fire management shall not inhibit
operation of emergency doors in accordance with 4.1.7. The ventilation and aerodynamic loading values
from the modelling/simulation shall form an input to the specification for the platform barrier system.
4.1.1.3 Structural design shall take into account 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 (5.1.3).
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 in EN 1991-1-1:2002, 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 the safety of a 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 5.1.3. 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.
It is recommended that, in addition, deflection of an infill panel that is structurally safe should not alarm
station users through large visible deformations relative to the frame in which the panel is mounted,
when subject to normal service conditions. Therefore, for serviceability considerations, the limiting
condition for deflection should be that the total horizontal displacement of the infill panel relative to the
frame at any point from its original unloaded position does 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 The calculations used in structural design shall be validated by load testing of a
representative structure.
NOTE 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 are
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 validated
mathematical analysis. Alternatively, thickness may be determined using empirical national codes.
Use of empirical codes can result in conservative design and increased weight. Calculated methods are
recommended where possible.
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 should not be
specified beyond what is essential in foreseeable conditions. “Over-design” may 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 a 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 platform barrier systems
that do not fully enclose the platform area shall be considered in the structural design of the barrier. 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 or moves alongside 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.
4.1.3.2.5 Wind loading shall be considered in accordance with EN 1991-1-4 (including associated
National Annexes).
4.1.3.3 Fatigue
4.1.3.3.1 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, Eurocode 3 — Design of steel structures - Part 1-9: Fatigue (for steel); and
— EN 1999-1-3, Eurocode 9 —Design of aluminium structures – Part 1-3: Structures susceptible to fatigue
(for aluminium).
4.1.3.3.2 The fatigue effects of aerodynamic loading from passing trains shall be considered for all
platform barrier systems. The fatigue spectrum should not be specified beyond what is essential in
foreseeable conditions. “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.
4.1.3.3.3 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.
4.1.3.3.4 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 doors and gates, or the fixed part of the façades, 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.
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 hazards 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 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, in particular 4.1.1
and 4.1.6.
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 body
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. This shall be achieved by ensuring that the degree of protection
corresponds to level IP3x of EN 60529.
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, in particular 4.1.1 and 4.1.6.
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 façade shall meet the general
requirements relating to fire and smoke performance and deflection under load, defined in the relevant
sections in this standard in particular 4.1.1 and 4.1.6. 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 flame and/or 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 for buildings 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. It is the responsibility of the entity in charge
of system integration to ensure that the fire performance of materials used, and fire scenarios considered
in the design, are appropriate to the context and location in which the barrier system is installed.
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
