Micro-grooves cannot compromise the locking system. The standard requires that the presence of grooves does not alter the width or length tolerance beyond ±0.5 mm for planks. Groove depth must be consistent across a production batch (±0.1 mm).
Background: Vienna Meidling is a busy interchange with trains passing at up to 160 km/h. Previously, no physical barriers existed.
Challenge: Install EN 17168 Class D barriers (200 km/h rating) on curved platforms without reducing passenger flow.
Solution: A custom glass-and-steel barrier with:
Results: After 18 months of operation:
Lessons Learned: The barrier’s maintenance interval was shortened from 36 months to 24 months due to high dust accumulation affecting the pneumatic gates. EN 17168 allows such adjustments in the maintenance plan.
EN 17168:2021 is the European standard specifically governing Platform Barrier Systems
(PBS) used in railway applications [1, 3]. Published by the European Committee for Standardization (
) in 2021, it provides a unified set of requirements for the design, construction, and operation of safety barriers—such as platform screen doors and gates—located at the edge of station platforms [1, 6]. Scope and Application
The standard is designed to ensure safety and system integration for barriers positioned adjacent to rail or other guided vehicles [3]. Systems Covered : It applies primarily to light rail (metros and tramways) but can also extend to heavy rail systems if specified by a project [1, 4]. Environment : It covers barriers in various settings, including sub-surface (underground), enclosed surface stations (e.g., air-conditioned platforms), and stations [1, 4]. Exclusions
cover barriers using ropes, bars, or those that operate vertically [4]. It also does not define fire performance requirements, though it mentions integration with such systems [4]. Key Technical Requirements
EN 17168 organizes requirements into several critical technical areas to ensure both physical integrity and operational safety [5]: Structural Design
: Defines loading conditions, glazing and panelling materials, and environmental factors like acoustic and thermal considerations [5, 11]. Types of Doors/Gates : Specific requirements are outlined for: Normal Passenger Doors : The primary interface for boarding and alighting [5]. Emergency Egress Doors
: Ensuring passengers can exit the track area safely in an emergency [11]. Driver Access Doors : Providing specialized entry for train crew [3, 11]. Platform Extremity Doors : Barriers at the ends of the platform [11]. Safety Risk Management : Addresses risks unique to barrier systems, most notably entrapment
—the danger of a person being caught between the train bodyside and the platform barrier after doors close [3, 7]. System Integration and Testing
A major focus of the standard is how these barriers interact with the wider rail network [3]: Synchronization
: Requirements for the coordinated opening and closing of vehicle doors and platform barriers [3]. Signaling Interface
: Integration with train control and signaling sub-systems to ensure the train is correctly aligned before doors operate [3]. Operational Performance
: Guidelines for testing the installation and ensuring the integrity of control systems through audible and visible alerts [3]. Implementation and Compliance en 17168
As a European standard, EN 17168 has been adopted by various national bodies, such as the NSAI in Ireland BSI in the UK [2, 3]. It serves as a benchmark for infrastructure owners, designers, installers, and operators
to ensure passenger safety and operational interoperability across European rail networks [4, 5]. for door synchronization or structural loading requirements under this standard?
EN 17168:2021 is the current European standard governing the design, construction, and operation of platform barrier systems in railway applications. Published by the European Committee for Standardization (CEN) in August 2021, it provides a comprehensive framework for implementing barriers like platform screen doors (PSDs) to enhance passenger safety and operational efficiency. Scope and Applicability
The standard applies to barriers positioned at the edge of station platforms, immediately adjacent to the rail or guided vehicles.
Transport Modes: It primarily covers metro, tram, and light rail systems, but can be applied to heavy rail if specified by a project.
Station Environments: It is relevant for sub-surface, enclosed, and open-air stations.
Exclusions: The standard specifically excludes barrier systems using ropes or bars, and those that operate in a vertical direction. Key Technical Requirements
The BS EN 17168:2021 document outlines several critical areas of concern for infrastructure owners and designers:
Structural Integrity: It defines physical and structural requirements, including loading conditions (such as wind pressure from moving trains) and guidelines for glazing and panel materials.
Operational Integration: A core focus is the synchronization of platform barrier doors with train doors to ensure safe passenger boarding and alighting. Safety Features:
Entrapment Prevention: Requirements to prevent passengers from being trapped between the vehicle and the barrier.
Emergency Egress: Specific provisions for emergency doors, driver access, and platform extremity gates.
Electrical Safety: Guidelines for earthing and bonding to maintain electrical safety on platforms equipped with these systems.
Fire Performance: While it includes requirements for fire resistance of materials and the use of barriers to minimize flame/smoke spread, it does not cover certain normative fire performance aspects covered by other specialized standards. Strategic Benefits for Railway Operators
Adhering to EN 17168:2021 offers several operational advantages beyond basic compliance: EN 17168:2021 - Platform barrier systems - iTeh Standards
EN 17168 is the European standard titled "Railway applications - Platform barrier systems," first published in 2021. It provides a comprehensive framework for the design, construction, and operation of platform screen doors (PSDs) and gates used at the edge of station platforms to separate passengers from tracks. Overview and Scope
The standard applies to metro, tramway, and light rail systems, as well as heavy rail where specified. It covers installations in sub-surface (underground), enclosed surface, and open-air stations.
Primary Purpose: To manage safety risks such as accidental or deliberate track incursion and contact between passengers and moving vehicles. Micro-grooves cannot compromise the locking system
Excluded Systems: It does not cover vertical barriers, systems using bars or ropes, or specific normative fire performance requirements for barriers acting as firewalls. Key Technical Requirements
The document, which spans 62 pages, details several critical areas for implementation:
Physical and Structural Integrity: Requirements for fixed structures, glazing/panelling, and environmental loading (including aerodynamic pressures from passing trains).
Door and Gate Varieties: Specifies requirements for passenger doors, emergency egress doors, driver access doors, and platform extremity doors.
System Integration: Guidelines for synchronizing vehicle doors with platform doors, audible and visible alerts, and interfacing with signaling and rolling stock subsystems.
Electrical and Control Systems: Covers the integrity of control logic, status indication, and earthing/bonding strategies to ensure electrical safety on platforms.
Testing and Verification: Outlines a normative testing plan (Annex A) including type, routine, functional, and systems-integration testing. Practical Benefits
Adherence to EN 17168:2021 allows infrastructure owners and operators to:
Enhance Safety: Reduce risks of entrapment and track-related accidents.
Improve Efficiency: Facilitate automated train operation and allow for higher train speeds entering and exiting stations.
Standardize Management: Provide a clear set of maintainability and accessibility guidelines, including for persons with reduced mobility.

EN 17168 adopts the same "AC" (Abrasion Class) system as EN 13329 but with modified definitions:
Additionally, EN 17168 introduces a "Groove Quality Grade":
Every 12 meters (or less), there must be a break-out panel or swing gate that:
When reviewing a product's technical file, look for:
If a supplier offers a "self-declaration" without third-party testing, reject it.
Myth 1: "EN 17168 is just a minor update to EN 13329." Reality: No. It is a separate standard. A product cannot claim both unless tested for both (rarely happens).
Myth 2: "All European laminate flooring automatically meets EN 17168." Reality: Only products explicitly labeled with "EN 17168" on the packaging or technical data sheet have been tested. Many budget micro-grooved floors are sold without any standard.
Myth 3: "A micro-groove is the same as a bevel." Reality: A bevel is typically at the plank edge (V-groove). EN 17168 covers grooves anywhere on the surface, including cross-grooves or embossed-in-register textures.
