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

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.

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.
