European foreword

This document (CLC/TS 50459-1:2021) has been prepared by CLC/SC 9XA “Communication,

signalling and processing systems”, of Technical Committee CLC/TC 9X “Electrical and electronic

applications for railways”.
This document supersedes CLC/TS 50459-1:2015.

CLC/TS 50459-1:2021 includes the following significant technical changes with respect to

CLC/TS 50459-1:2015:

— updated general principles for the presentation of ERTMS/ETCS/GSM-R information in line with

ERA_ERTMS_015560;
— updated ergonomic arrangements in line with the EN 16186 series.

This document is expected to be read in conjunction with ERA_ERTMS_015560 “ETCS Driver

Machine Interface” and the EN 16186 series, “Railway applications — Driver's Cab”.

The CLC/TS 50459 series consists of the following parts under the general title “Railway

applications – Communication, signalling and processing systems – European Rail Traffic

Management System – Driver-Machine Interface”:

— Part 1: General principles for the presentation of ERTMS/ETCS/GSM-R information;

— Part 2: Ergonomic arrangements of GSM-R information;
— Part 3: Ergonomic arrangements of non ETCS information.

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. CENELEC shall not be held responsible for identifying any or all such patent rights.

This document has been prepared under a mandate given to CENELEC by the European Commission

and the European Free Trade Association.

Introduction

The CLC/TS 50459 series contains the ergonomic arrangements for the display of information on the

Control and Command Display (CCD) and Train Radio Display (TRD). Most items are illustrated with

an example.

The reasons for defining the ergonomics of the Driver-Machine Interface (DMI) are as follows:

— achieving harmonized and coherent presentation for ERTMS/ETCS and NTC information. Given

the large number of NTC’s requiring the use of the ERTMS/ETCS DMI, only a harmonized

approach is feasible;

— defining DMI ergonomics that is compatible with agreed interoperable ERTMS specifications;

— to reduce the risk of incorrect operation by a driver;

— facilitating train operation with a unified DMI, hence reducing the cost of driver training;

— better understanding of the tasks to be performed;
— increasing speed and accuracy of driver actions.

1 Scope

This document describes how ERTMS and non-ERTMS information will be arranged and displayed

from an ergonomic point of view. More specifically, it covers information that is out of the scope of

ERA_ERTMS_015560. This document describes more ergonomic details than currently provided by

the ERTMS/GSM-R specifications.

This document defines the ergonomics for the Driver-Machine Interface (DMI) for the following

applications:
— stand-alone ERTMS/GSM-R Train Radio Systems;
— non-ERTMS/ETCS Train Control Systems;
— other technical systems currently provided on the rolling stock.
The ergonomics covers:

— the general arrangements (dialogue structure, sequences, layout philosophy, colour philosophy),

— the symbols,
— the audible information,
— the data entry arrangements.

This document is limited to ergonomic considerations and does not define the technology to be used

for the implementation but it does give guidelines about how to implement the requirements using

different technology types (soft keys, touch screen device, LCD, electromechanical instruments,

indicator lamps, etc.).

This document is applicable to all trains fitted with the ERTMS/ETCS and also to trains fitted with train

radio (GSM-R) DMI.

The scope of this document is to define ergonomic principles for the interface between the driver and

the above listed applications.
TDD is out of scope of the CLC/TS 50459 series.

For human factor items, such as display of information, display location, viewing angles and

organization of the screens, see EN 16186 series.

Machine Interface” and the EN 16186 series, “Railway applications — Driver's Cab”.

The CLC/TS 50459 series consists of the following parts under the general title “Railway

applications – Communication, signalling and processing systems – European Rail Traffic

Management System – Driver-Machine Interface”:

— Part 1: General principles for the presentation of ERTMS/ETCS/GSM-R information;

— Part 2: Ergonomic arrangements of GSM-R information;
— Part 3: Ergonomic arrangements of non ETCS information.

Introduction

The CLC/TS 50459 series contains the ergonomic arrangements for the display of information on the

Control and Command Display (CCD) and Train Radio Display (TRD). Most items are illustrated with

an example.

The reasons for defining the ergonomics of the Driver-Machine Interface (DMI) are as follows:

— achieving harmonized and coherent presentation for ERTMS/ETCS and NTC information. Given

the large number of NTC’s requiring the use of the ERTMS/ETCS DMI, only a harmonized

approach is feasible;

— defining DMI ergonomics that is compatible with agreed interoperable ERTMS specifications;

— to reduce the risk of incorrect operation by a driver;

— facilitating train operation with a unified DMI, hence reducing the cost of driver training;

— better understanding of the tasks to be performed;
— increasing speed and accuracy of driver actions.

1 Scope

This document describes how ERTMS and non-ERTMS information will be arranged and displayed

from an ergonomic point of view. More specifically, it covers information that is out of the scope of

ERA_ERTMS_015560. This document describes more ergonomic details than currently provided by

the ERTMS/GSM-R specifications.

This document defines the ergonomics for the Driver-Machine Interface (DMI) for the following

applications:
— stand-alone ERTMS/GSM-R Train Radio Systems;
— non-ERTMS/ETCS Train Control Systems;
— other technical systems currently provided on the rolling stock.
The ergonomics covers:

— the general arrangements (dialogue structure, sequences, layout philosophy, colour philosophy),

— the symbols,
— the audible information,
— the data entry arrangements.

This document is limited to ergonomic considerations and does not define the technology to be used

for the implementation but it does give guidelines about how to implement the requirements using

different technology types (soft keys, touch screen device, LCD, electromechanical instruments,

indicator lamps, etc.).

This document is applicable to all trains fitted with the ERTMS/ETCS and also to trains fitted with train

radio (GSM-R) DMI.

The scope of Part 1 of CLC/TS 50459 is to define ergonomic principles for the interface between the

driver and the above listed applications.
TDD is out of scope of the CLC/TS 50459 series.

For human factor items, such as display of information, display location, viewing angles and

organization of the screens, see EN 16186 series.
