Overview

CLC/TS 50459-3:2021 - "Railway applications - European Rail Traffic Management System - Part 3: Ergonomic arrangements of non ETCS information" provides ergonomic rules for arranging and displaying non-ETCS information on the driver-facing control display (CCD/DMI). Approved by CENELEC in 2021, the Technical Specification complements ETCS human‑machine interface work by defining how additional national or auxiliary system information should appear when integrated into the ETCS DMI. It explicitly addresses two DMI implementation technologies: touch screen and soft key input methods.

Key topics and technical requirements

• Scope and exclusions
  • Covers ergonomic layout, symbols, audible cues and data entry for non‑ETCS objects shown on the CCD.
  • Does not duplicate ERA_ERTMS_015560; material already in that ERA document is excluded.
  • National systems not integrated within the ETCS DMI and redundancy concepts are out of scope.
• Ergonomic layout and screen areas
  • Prescribes placement of non‑ETCS information relative to ETCS objects and defined DMI grid areas.
  • Defines default windows, sub‑level windows and menu behavior for integrated systems.
• Symbols and unified DMI service
  • Specifies symbol families and status/mode indicators for non‑ETCS functions to ensure a coherent visual language across the DMI.
• Audible information
  • Covers audible alerts and sound design for non‑ETCS systems and driver activity warnings.
• Data entry and interaction
  • Describes ergonomics for data entry windows, touch targets (touch screen) and soft key mappings (soft key implementations).
• Annexes with national system examples
  • Informative annexes describe integration patterns for specific NTCs (e.g., LZB/PZB, UK NTC, ATC2, SCMT, SHP, JKV) including area descriptions, symbols and sounds.

Applications and who uses it

This TS is practical for:

• DMI/UI designers and human factors engineers designing in‑cab interfaces for ETCS-equipped vehicles.
• On-board system manufacturers and integrators implementing non‑ETCS functionality within the ETCS DMI.
• Signalling engineers and vehicle suppliers ensuring consistent presentation of national train control (NTC) overlays.
• Rail operators and national safety authorities validating driver interfaces for ergonomics, usability and interoperability.

Benefits include improved driver situational awareness, consistent symbol and sound design, and smoother integration of national systems into the ETCS DMI.

Related standards

• ERA document ERA_ERTMS_015560 (ETCS DMI core content) - complementary reference and scope delimiter.
• CENELEC / CLC procedural framework (members required to publish the TS nationally).

4 General principles
4.1 Purpose of document
4.1.1 General
A clear and consistent definition of the non ETCS driver machine interface helps the driver to better
understand the tasks he has to perform. This increases the speed and the accuracy of interactions
between the driver and the non ETCS on-board equipment (NTC and/or other on-board systems),
hence reducing the probability of human errors.
Moreover, harmonizing the presentation of displayed information and the driver’s interactions with the
equipment, contributes to a unified operation of the trains regardless of which suppliers’ products they
are fitted with. This reduces further the potential for human errors, reduces the driver training
requirement and facilitates cross-acceptance of equipment.
Annex A gives existing examples for the integration of NTC and/or other on-board systems.
Annex B gives existing examples of the sounds for NTC and other train functions.
The lists given in Annex A and Annex B are not exhaustive.
4.1.2 Ergonomic arrangements of areas of the ETCS layout
For the definition of non ETCS screen layouts (NTC or other on-board systems) the basic layouts
described in CLC/TS 50459-1 and ERA ERTMS 015560 should apply.
The basic layouts apply for a ‘Unified DMI’ as defined in ERA ERTMS 015560. For a ‘Customized DMI’
it is possible to modify these layouts for NTC operation.
The basic layouts for touch screen technology and soft key technology, shown in Figure 1 and
Figure 2, are taken from document ERA ERTMS 015560. In the event of a conflict between this
document and ERA ERTMS 015560, the ERA document shall prevail.

Figure 1 — The sub areas of the ERTMS/ETCS layout (touch screen technology)
Figure 2 — The sub areas of the ERTMS/ETCS layout (soft key technology)
4.1.3 ETCS objects
Even if authorized by national rules, for ergonomic reasons the size and location of ETCS objects
should not be changed.
4.1.4 Non ETCS objects
For displaying a NTC and other on-board systems (e.g. DAC) together, the position and size of the
objects shall be arranged to prevent overlapping.
4.2 Audible information for non ETCS systems
According to ERA ERTMS 015560 audible information for a non ETCS system should be sent
specified by a sequence of segments defined by a duration and an associated frequency sent to the
ERTMS/ETCS on-board system (unified DMI).
For a customized DMI the audible information should be provided in wave form, e.g. as *.wav files.
If a non ETCS system requires its own audible information this is mentioned in the corresponding
section.
Examples of audible information mentioned in this document are described in Annex B.
4.3 Data entry
Data entry should follow the principles of ERA_ERTMS_015560. Repeated Entry of the same data
should be avoided.
5 Non ETCS symbols
5.1 General requirements for unified DMI service
The available areas for NTC buttons and indicators are defined in ERA ERTMS 015560.
Speed and distance supervision information sent by the NTC shall be displayed by the ETCS DMI
according to ERA ERTMS 015560.
NOTE For touch screen technology, some areas can be used for buttons or indicators, depending on the
need of the National System.
5.2 Symbols for other train functions
The symbols for other train functions (e.g. DAC, Passenger Alarm initiated brake application, Open
Door Alarm, Main Circuit Breaker) shall be in accordance with EN 16186-3:2016+A1:2018, Annex A.
Annex A
(informative)
Integration of NTC and/or other on-board systems
A.1 Usage of screen areas
All areas marked in yellow colour within the following figures are used by NTC and/or other on-board
systems.
All areas marked in orange colour within the following figures are used by ETCS and are moved with
respect to the ETCS layout.
All areas marked in red colour within the following figures are used by NTC or other on-board systems
and ETCS.
The ergonomics of the examples are based on the area arrangements for the ETCS layout (see
Figure 1 and Figure 2).
A.2 NTC LZB/PZB
A.2.1 LZB/PZB - Scope and field of specification
This example shows the interface between the driver and the LZB/PZB on-board regarding to the use
in context with ERTMS/ETCS and as standalone system (LZB/PZB in fallback mode).
The specification describes two possible technologies for implementing the LZB/PZB DMI, namely
touch screen or soft key.
The requirements regarding LZB/PZB are defined in PLZB_DMI_REQUIREMENTS [19], [20], [27] and
[28].
A.2.2 LZB/PZB - Overview
Figure A.1 and Figure A.2 explain the usage of the ETCS DMI areas.
Figure A.1 — The sub areas of the LZB/PZB layout (touch screen technology)
Figure A.2 — The sub areas of the LZB/PZB layout (soft key technology)
To avoid competitive use of the text area, the LZB/PZB text messages are displayed as private areas
(PLZB_E5/6/7) outside ETCS scrolling. For ETCS messages only areas E8/9 (touch screen
technology) respectively area E8 (soft key technology) are available.
A.2.3 LZB/PZB - Positioning onto the grid array

A.2.4 LZB/PZB - ETCS and NTC information shown on a LZB/PZB default window
A.2.4.1 LZB/PZB - Introduction
The layers on the LZB/PZB default window have different or additional requirements to
ERA ERTMS 015560 as follows:
— Layer 0: no change;
— Layer −1: PLZB_A3, PLZB_C1, PLZB_C2, PLZB_C3, PLZB_C4, PLZB_C5, PLZB_C6;
— Layer −2: PLZB_B8, C1 (in area B).
A.2.4.2 LZB/PZB - ETCS objects
The area C1 is moved to area B.
A.2.4.3 LZB/PZB - NTC objects
A.2.4.3.1 LZB/PZB - General
The LZB/PZB text messages are displayed in area PLZB_E5/6/7.
The cursor buttons E10 and E11 are without effect to the area PLZB_E5/6/7. The scrolling has only
effect to the text messages in area E8/9 (touch screen technology) respectively in area E8 (soft key
technology).
The LZB/PZB text messages have to remain different from ETCS text messages, because they
always have to be seen in the context of the indicators in PLZB_C1/2/3/4/5/6.
The text messages for LZB/PZB are defined in PLZB_DMI_REQUIREMENTS [19], [20], [27] and [28].
A.2.4.3.2 LZB/PZB - Indicators PLZB_C1/2/3/4/5/6
The indicators PLZB_C1/2/3/4/5/6 are displayed according to PLZB_DMI_REQUIREMENTS [20], [27]
and [28].
