Railway applications - Design for PRM Use - General Requirements - Part 2: Information

This European Standard describes the specific ‘Design for PRM use’ requirements applying to
both infrastructure and rolling stock and the assessment of those requirements. The following
applies to this standard:
— The definitions and requirements describe specific aspects of ‘Design for PRM use’ required
by persons with disabilities and persons with reduced mobility as defined in the PRM TSI.
— This standard defines elements which are universally valid for obstacle free travelling
including lighting, contrast, tactile feedback, transmission of visual and acoustic
information. The definitions and requirements of this standard cover the infrastructure and
the rolling stock applications.
— This standard only refers to aspects of accessibility for PRM passengers it does not define
non PRM related requirements and definitions.
— This standard assumes that the infrastructure or rolling stock is in its defined operating
condition.
— Where minimum or maximum dimensions are quoted these are absolute NOT nominal
requirements.
The ‘General requirements’ standard is written in three parts:
— Part 1 contains
— contrast;
— This document is Part 2 and contains
— spoken information;
— written information;
— tactile information;
— pictograms;
— Part 3 contains
— lighting;
— low reflective properties;
— transparent obstacles;
— slip resistance.
Terms and definitions for systems and components
The task is to describe clear and consistent terms and definitions. Where measurement methods and/or assessment procedures are needed to allow a clear pass/fail assessment, this task shall be done as well.
Existing European standards shall be taken into account for this work.
