Introduction
This Technical Specification forms Part 1 of a series, the other parts being:
CLC/TS 50459-2 for ergonomic arrangements of ERTMS/ETCS information
CLC/TS 50459-3 for ergonomic arrangements of ERTMS/GSM-R information
CLC/TS 50459-4 for data entry procedure for ERTMS/ETCS/GSM-R
CLC/TS 50459-5 for symbols for ERTMS/ETCS/GSM-R
CLC/TS 50459-6 for audible information for ERTMS/ETCS/GSM-R
These Technical Specifications contain the ergonomic arrangements of information on the ERTMS DMI
Display. Most items are illustrated with an example.

1 Scope
This Technical Specification describes from an ergonomic point of view how ERTMS information shall be
arranged and displayed. This Technical Specification describes more ergonomic details than currently
provided by the ERTMS/ETCS/GSM-R specifications.
This Technical Specification defines the ergonomics for the Driver-Machine Interface (DMI) for the
ERTMS/ETCS Train Control System, and for the integrated ERTMS/GSM-R Train Control and Train
Radio Systems, and for the stand alone ERTMS/GSM-R Train Radio Systems and for other technical
systems currently provided on the rolling stock.
The ergonomics covers the
 general arrangements (dialogue structure, sequences, layout philosophy, colour philosophy),
 symbols,
 audible information,
 data entry arrangements.
The aims of the ERTMS/ETCS/GSM-R Train Control and Train Radio Systems are standardised systems
facilitating interoperable movement of trains and permitting economies of scale in procurement and
operations. The objective of this Technical Specification is to define the minimum requirements on the
DMI that are necessary to enable these objectives to be achieved. Hence the Technical Specification is
limited to ergonomic considerations and does not define the technology to be used for the implementation.
The reasons for defining the ergonomics of the DMI are as follows:
 achieving harmonised and coherent presentation for ERTMS/ETCS and STM information. Given the
large number of STM’s requiring the use the ERTMS/ETCS DMI, only a harmonised approach is
feasible;
 defining Driver-Machine Interface ergonomics that is compatible with agreed interoperable ERTMS
specifications;
 to reduce the risk of incorrect operation by a driver working with different trains fitted with
ERTMS/ETCS and ERTMS/GSM-R;
 facilitating train operation with a unified ergonomics, hence reducing the cost of driver training.
This Technical Specification is applicable on all trains fitted with the ERTMS/ETCS and also for trains
fitted with train radio (GSM-R) DMI.
The scope of Part 1 of the Technical Specification CLC/TS 50459 series is to define ergonomic principles
for the interface between the driver and ERTMS/ETCS/GSM-R.
This specification gives guidelines how to implement different technology (soft keys, touch screen device,
LCD, cathode tube, etc.)
