Railway applications — Vertical barrier systems

Апстракт

This document specifies requirements for the design, construction and operation of vertical barrier systems using doors/gates that utilize bars and ropes moving in the vertical direction 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 to mitigate the risk of passengers falling from platform due to inattention. This vertical barrier system does not provide a continuous barrier that prevents body parts such as arms, legs or heads from passing through the vertical barrier system.

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 vertical 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.

This document does not cover barrier systems set back from the platform edge, which are used to control access to trains or for crowd management, however, relevant sections of the document could be used as guidance.

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 vertical 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 applies to all persons involved in the implementation and system integration of a vertical barrier system, including infrastructure owners, designers, installers and operators.

This document does not cover normative requirements:
- relating to fire performance or fire requirements arising from use of vertical barrier systems as fire barriers; or
- for platforms, or other foundations and structures to which the barrier system is secured.
