The standard covers several key aspects, including:
Manual push-out or sliding panels that permit immediate evacuation from the trackside back onto the platform in the event of an emergency.

Mechanical and Structural Loading
The most critical interface is between the platform barrier doors and the train's own doors. The standard requires a to ensure that the platform doors only open when the train is correctly stopped and its doors are opened, and that they close safely before the train departs. This is a complex safety function that often relies on dedicated signaling or communication-based train control (CBTC) systems. : Standardizes low-to-medium speed urban boarding points
: Safely permits higher train speeds during station entry/exit through precise door synchronization. Climate & Comfort
Install EN 17168 Class D barriers (200 km/h rating) on curved platforms without reducing passenger flow.
EN 17168 does not explicitly govern barrier systems utilizing manual ropes or bars, nor does it cover barriers operating in a vertical (up-and-down) movement style. However, its core risk management strategies can still serve as design guidance for those alternative systems. Core Physical and Structural Requirements
