European foreword
This document (prEN 16186-7:2024) has been prepared by Technical Committee CEN/TC 256 “Railway
applications”, the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
EN 16186 Railway applications — Driver’s cab consists of the following parts:
— Part 1: Anthropometric data and visibility;
— Part 2: Integration of displays, controls and indicators;
— Part 3: Design of displays;
— Part 4: Layout and access;
— Part 5: External visibility for tram vehicles;
— Part 6: Integration of displays, controls and indicators for tram vehicles ;
— Part 7: Design of displays for tram vehicles ;
— Part 8: Tram vehicle layout and access.
NOTE Part 1 to 4 above-mentioned standards are only applicable for heavy rail vehicles.

Under development.
This document, under development.
Introduction
The requirements of this standard, which interface with vehicle functions, have been elaborated with the
commitment to respect the standards specifying these functions and in addition to respect the state of
the art of other rolling stock functions.
The reasons for defining the information are as follows:
— achieving harmonized and coherent presentation of information;
— defining Driver-Machine Interface ergonomics that is compatible with agreed interoperable
specifications;
— to reduce the risk of incorrect operation by a driver working with different tram vehicles fitted with
displays;
— facilitating tram vehicle operation with unified ergonomics, hence reducing the cost of driver training.
Information designed according to this standard is deemed to fulfil the following basic principles:
— be clear, correct and necessary;
— indicate its priority, whether by positioning, size, colour, sounds, sound levels, etc.;
— minimize confusion of the driver;
— prevent unnecessary distraction of the drivers' attention while performing their normal duties.
If a requirement contains an option, the choice of this option is purely up to the applicant.
NOTE 1 The term “option” is to be understood as a possibility that is usually expressed by the word “can”.
NOTE 2 In the context of this document, “tram vehicles” also means “tram-trains”.

1 Scope
This document is applicable to vehicles operating on tram networks.
This document specifies all necessary design rules and associated assessment criteria as well as guidance
concerning the design of information and the corresponding user interfaces of driver’s cabs of tram
vehicles.
It considers the tasks the driver has to carry out and human factors. This document specifies how
information is arranged and displayed.
All assessments based on the normative requirements of this document are applicable mainly to:
— symbols provided by Annex A;
— arrangement of screen areas conform with Figure 1 (generic organization of information);
— colours, fonts;
— audible information.
This document is applicable to the following aspects:
— legibility and intelligibility of displayed information: general rules concerning the layout of
information on the displays, including character size and spacing;
— definition of harmonized colours, symbols, etc.;
— definition of harmonized principles for the command interface (by physical or touchscreen buttons):
size, symbols, reaction time, way to give feedback to the driver, etc.;
— general arrangements (dialogue structures, sequences, layout philosophy, colour philosophy),
symbols, audible information, data entry arrangements.
NOTE If this document deals with how information can be given for operation and in degraded situations, it
does not define operating rules and degraded situations.
