En 17168

The European standard establishes the mandatory framework for the design, construction, integration, and operation of platform barrier systems (PBS) within railway environments. Developed by the European Committee for Standardization (CEN), this 62-page document unifies technical specifications for automated movable doors and gates positioned directly at the platform edge. The primary goal of EN 17168 is to physically segregate passengers from tracks and moving transit vehicles to prevent accidental falls, manage overcrowding, and optimize train throughput. Scope and Applicability

The systems must be designed for high-frequency operations, minimizing downtime and maintaining high availability during peak hours. 4. Significance of EN 17168 in Modern Railways

Notably, EN 17168 does provide normative fire performance requirements for platform barriers used as fire barriers. This is explicitly stated in Clause 1 and reiterated throughout. However, platform barrier installations may be incorporated into tunnel fire safety strategies, including smoke management and ventilation.

The primary goal is to minimize risks to passengers.

EN 17168 is structured to address all critical aspects of platform barrier systems, divided into several comprehensive sections.

Reducing the risk of falls into the track area. Scope and Applicability The systems must be designed

Electrical Safety – Earthing and Bonding – Annex C provides informative principles for earthing and bonding strategies, offering two options: bonding the system to station earth or insulating it from earth and the traction current return circuit (i.e., floating).

For a platform barrier system to be fully compliant with EN 17168, it must undergo a series of verification processes. The standard references a multi-stage testing framework:

is the European standard specifically dedicated to platform barrier systems (commonly known as platform screen doors or PSDs) installed at the edge of station platforms. Standard Designation: EN 17168:2021 (Railway applications)

The standard is designed for a broad range of professionals within the railway infrastructure industry, including: This is explicitly stated in Clause 1 and

The guidelines apply globally across all platform types, including:

: Sub-surface (tunnels), enclosed, and open-air stations.
