A INTRODUCTION

A1 Objective

The objective of this work package is to achieve a harmonised ERTMS DMIthat supports the driver when carrying out tasks related to ERTMS operation.

A2 Purpose

The purpose of this document is to demonstrate that supporting information tobe displayed on the DMI as required by the operational rules has been

captured within the CENELEC SC9XA draft Euronorm of January 2004produced by WGA9D and the DMI indications are fit for purpose from anoperation viewpoint. This document is an interim version in order to give up todate information and direction to our industry and railway partners.

A3 Scope

The scope of this document is based upon CENELEC SC9XA Euronorm draftof January 2004. It is, therefore, necessary to understand that changes to theEuronorm may render some of this document as invalid. Certain sectionswithin this document are, as yet, not validated as they are under assessment

by EEIG (e.g. Human Factors, Safety, and Operations).

A4 Structure

The numbering used in this document is aligned with that used within theEuronorm to assist in comparison study.

If symbols are described in Part 5 they shall be used.If the indication is not described in Part 5 a text label or message should beused. The use of a new symbol for a new indication is not precluded.

4.1.1.3 Use of colours

The main operational colours of the DMI are white, grey, yellow, orange andred. The colours express the priority of the information presented. Priority islinked to the expected driver reaction time.

No immediate attention/action required (base priority): white/greyshall be used; the information concerns a normal situation.

Attention/action required (medium priority): yellow shall be used;the information still concerns a normal situation and there is no danger;after a while more attention/action may be required.

Immediate attention/action necessary (high priority): orange shallbe used; the situation is undesirable and may be unexpected;immediate action is necessary to avoid further undesirable effects.

Urgent attention/action necessary (highest priority): red shall beused; the information concerns an unusual, unexpected, dangerousand/or harmful situation (example: train trip, emergency call).

Table 1: Colour philosophy DMI

Urgency Colour Expected situation if not reacted in time

no danger at all white / grey normal, no immediate reaction required

no danger yet yellow no reaction might lead to orange, be prepared totake action

becoming a danger orange no reaction might lead to red, action required

danger / unwantedsituation

red can lead to orange, yellow or white/grey after appropriate action, too late to react / systemintervention is possible

The difference between the use of white and grey depends on the need for amore conspicuous presentation.

This specification is based on a dark blue background.

Although another background can be imagined, the use of the dark bluebackground is strongly recommended because it guarantees an optimumcontrast ratio.

As an informative example (Table 2) the following 24-bit RGB colour valuesare used in this standard for the figures.

When using a monochrome display for a standalone GSM-R DMI, a similarergonomic approach to ETCS shall be followed but without the use of colour.

4.1.1.4 Use of flashing

Flashing shall be used to draw the attention of the driver to a certain part of

the display or to draw attention to a delay-type button (4.4.2.5). Symbols usedon indicators, and frames can flash.

When flashing is used, the related information shall change from visible to notvisible (e.g. background colour) with a nominal frequency of 2 Hz with asymmetrical mark space ratio.

Remark: the use of flashing should not be confused with the use of sound.

4.1.1.5 Use of frames

A steady frame is used for the following: to indicate that a function is active.

A flashing frame is used for the following:

in combination with text messages or text labels onbuttons/indicators (text messages or text labels on buttons/indicatorsthemselves are not allowed to flash).

1The colours defined in Table 2 are the nominal colours.


8/113


9/113



the active form of verbs shall be used

dual negations and negative questions shall be avoided

capitals and lower-case characters shall be used as in text onpaper

short main sentences should be used

text shall be in grey or white

4.1.3 Characters

Displays are based on pixels. To optimise readability, the chosen characterfont shall be optimised for display use (e.g. no serifs).

The following items have to be taken into consideration: Character height

Character width

Character stroke width

Between-character spacing

Between-word spacing

Between-line spacing

4.1.3.1 Character type

The character type shall not use serifs.

It is recommended to use bitmap based fonts optimised for screen use for allreal time drawing purposes (e.g. proportional characters for labels, textmessages, etc.) such as Chicago.

Information that can be prepared in advance (e.g. numbers on the speed

scale) can be drawn with any good readable non-serif font such as Helvetica.

In particular cases e.g. the actual speed numbers, a non-proportional specialcharacter optimised for display use can be developed and used.

4.1.3.2 Character height

The minimum height of the characters shall be:

Speed scale numbers: 14 cells

Actual speed (digital): 17 cells


10/113



Other characters (e.g. used for input fields, text messages, etc.):lower case: 7 cells upper case: 9 cells

4.1.4 Numbers

When using numbers, leading zeros shall not be shown (e.g. show 80 km/hnot 080 km/h), unless it is essential (e.g. telephone number).

Section 4.2 Principles for dialogue

This clause deals with software aspects and describes general ergonomicprinciples for the dialogue between user and system, which are independentof any specific dialogue technique. For the principles in this clause ISO 9241

part 10 is used as a reference.The dialogue principles are intended to make the use of the system easier.Although the ISO 9241 standard refers to office work, the dialogue principlesalso apply to a driver-machine interaction in the driving cab.The aim is to design a dialogue, which allows the user to plan and performwork under ergonomically favourable conditions, which take the psychologicalcharacteristics of the user into consideration.The dialogue principles are not independent, and it may be necessary to tradeoff the benefits of one principle against another. The applicability and therelative importance will vary with the specific field of application, user groups,and the dialogue technique chosen.

4.2.1 Suitability for the task

A dialogue is suitable for a task when it supports the user in the effective andefficient completion of its task.

4.2.2 Self-descriptiveness

A dialogue is self-descriptive when each dialogue step is immediatelycomprehensible through feedback from the system or is explained to the userwhen requesting the relevant information.

4.2.3 Controllability

A dialogue is controllable when the user is able to maintain direction over thewhole course of the interaction until the point at which the goal has been met.

It should be possible for ERTMS and the driver to postpone actions withoutlosing them.

4.2.4 Conformity with user expectations

A dialogue conforms with user expectations when it corresponds to the users

task knowledge, education, experience, and to commonly acceptedconventions.


11/113



Frequently used functions and those used while driving should be easilyaccessible (e.g. by means of one keystroke).

4.2.5 Error guidance

A dialogue gives error guidance when, despite errors in input, the intendedresult can be achieved with minimal corrective action having to be taken.

Section 4.6 Acknowledgements

Acknowledgement (ACK) can be made on the DMI, but also outside the DMI.If done on the DMI, the arrangement of the acknowledgement button(s) isequal to the arrangement of the other buttons. If done outside the DMI thearrangement is not part of this standard.

Only one request for ACK at any given time shall be presented

to the driver.

There shall be sufficient reaction time for the driver to activatethe ACK after the request for ACK is presented.

ACKs shall be sequentially presented.

A minimum delay-time of nominally 1 sec shall be respectedbetween an ACK and the next request for ACK.

The ACK-button shall be an up-type button.

A request for an ACK of a text message or an indicator with atext label shall be presented with a flashing frame around the messagewindow or indicator field. After the ACK action the flashing will stop todisplay that the ACK has been taken into account by the ERTMS/ETCSsystem.

A request for an ACK of an indicator with a symbol as a labelmay be presented with the flashing symbol itself. After the ACK actionthe flashing will stop to display that the ACK has been taken intoaccount by the ERTMS/ETCS system.

5.1 Principles

The figures2in this clause show the DMI when all information is combined into

one screen.

Note: The figures are shown as examples to help explaining the requirements

and do not mandate any technology although the figures are based on ascreen using touch screen technology.

5.2 Speed and Supervision information

5.2.1 Speed Information

5.2.1.1 Speed dial

5.2.1.1.1 Description

This DMI object displays the speed dial.

5.2.1.1.2 Location and size

The speed dial shall be displayed in area B0.The area size is 280 x 300 (w x h) cells.

Figure 6 Screen location of the speed dial

5.2.1.1.3 Examples

a. 400 km/h scale b. 250 km/h scale

Figure 7 Two scales for the DMI


14/113



5.2.1.1.4 Display requirements

The speed dial is circular and indicates speeds from 0 km/h to 400 km/h orfrom 0 km/h to 250 km/h depending on the type of the engine. The speeds are

spaced around the border of the circle as follows.

For the 400 km/h scale:Assuming that 0 degrees is vertically upwards from the centre, 0 km/h isshown at an angle of -140 degrees and 400 km/h is shown at an angle of+140 degrees, while 200 km/h is shown at an angle of +40 degrees.

This means that the mapping from speed to the angle of the pointer indicatingthe speed is divided into two segments: the first segment ranges over theangles -140 to +40 degrees with speeds from 0 to 200 km/h and the secondsegment ranges over the angles +40 to +140 degrees with speeds from 200

to 400 km/h.

Both segments have linear mapping between speed and angles.

The speed dial with the 400 km/h scale shall indicate the following numbers:0, 50, 100, 150, 200, 300 and 400, positioned inside the circle of the dial. Ateach of these positions a speed indicator line is drawn radially between theborder of the circle and the number. In between these lines are, evenlyspaced, similar speed indicator lines, but a little shorter.

This means that in the first segment (from 0 to 200) the distance between the

10 km/h indications is wider than in the second segment (from 200 to 400).

The functions displayed in B1 and B2 also use the mapping described here.

For the 250 km/h scale:Assuming that 0 degrees is vertically upwards from the centre, 0 km/h isshown at an angle of -140 degrees and 250 km/h is shown at an angle of+140 degrees.

The speed dial with the 250 km/h scale may indicate the following numbers: 0,20, 40, 60, 80, 100, 120, 140, 160, 180, 200, 220 and 240, or 0, 50, 100, 150,

200 and 250. At these speeds also a speed indicator line is drawn from theborder of the circle into the direction of the centre. In between these lines are,evenly spaced, similar speed indicator lines, but shorter.This scale shall have a constant mapping.

When not under Full Supervision (e.g. SR, OS) the information shown on areaB should be limited to a national value (e.g. 170 km/h) and the scale ends atthat value (see figure in clause 5.2.1.5).This is done to distinguish clearly between FS and other modes.

Any scale shall be designed and elaborated using the best graphical

techniques (e.g. anti-aliasing) to achieve a smooth appearance of thenumbers and markers.

Additional dimensions: large markers 25 cells (length); short markers 15 cells(length).

5.2.1.2 Current train speed pointer


This DMI object displays the current speed of the train.


The current train speed pointer shall be displayed in area B1.Figure shows an example of the size of the pointer.

16/113



5.2.1.2.3 Example

Figure 10 Current train speed pointer

5.2.1.2.4 Display requirementThe speed is shown by a pointer in the centre of the speedometer. It showsthe same speed as the DMI object actual speed digital'.The pointer indicates a speed between 0 and 400 km/h (or 250 km/h),according to the speed dial (see 5.2.1.1). The pointer consists of a needle anda circular centre point. Both parts always have the same colour.In the centre of the pointer the numeric value of the actual speed shall bepresented in digits; see for more details clause 5.2.1.3.

The width of the circular centre shall have at least the size to cover thenumbers of the digital current train speed.

The length of the pointer shall not reach the hook of the CSG (see clause5.2.1.4).The width of the top of the pointer shall not be wider than the hok of the CSG.The example of Figure 5 should be used as a guideline.

The pointer follows the DMI colour philosophy; for more details see clause 4.2in this standard and Part 1. If the speed has for example a value which is inthe grey area, the pointer shall be grey.One exception: if area of the speed is dark grey, the pointer shall be grey tomeet a better contrast.


17/113



5.2.1.3 Current train speed digital


The current speed of the train is also displayed digitally. It shows the samespeed as the function 'Current train speed pointer' (see clause 5.2.1.2).


The current train speed digital shall be displayed in the the centre of thepointer in area B1.The characters of the current train speed digital shall be at least 17 cellsheight.

Figure 11 Screen location for the current train speed digital

5.2.1.3.3 Example

Figure 12 Current train speed digital


18/113



5.2.1.3.4 Display requirement

The current speed is shown digitally in B1 with three digits. Area B1 is dividedinto three equally sized sub areas. Every digit is placed in such a sub area: inthis way the digits will not change location depending on the different widths ofthe 10 digits. Preceding zeros are never shown.The digits shall be aligned from the right and shall not be proportional (fixedwidth shall be used).

5.2.1.4 Circular Speed Gauge (CSG)


The Circular Speed Gauge (CSG) displays, around the speed dial, the V-permitted, V-target, V-intervention and V-release speed information.


The CSG shall be displayed in area B2.Figure 14 shows an example of the size of the CSG.

19/113



5.2.1.4.3 Audible information

The sounds S1, S2, S3 and S5, see Part 6, can be used depending on thecurrent train speed (see clause 4.2).

5.2.1.4.4 Example

Figure 15 Circular Speed Gauge (CSG)


The CSG shall be placed along the outside border of the speed dial, but from -145 degrees to +145 degrees. In normal situations the CSG shows the driverthe V-permitted and the V-target speeds by filling it in with dark grey from -145degrees to the V-target speed, and from V-target to V-permitted with grey.

Note: The reason for the CSG to have a slightly larger range of angles thenthe speed scale, is to permit the display a target speed of 0 km/h. In this casethe part of the CSG is filled from 145 degrees to 0 km/h with dark grey. Theslightly larger part at the start of the bar (e.g. below 0 km/h) will neverdisappear.

At V-permitted the CSG is about twice as wide for a few degrees, overlappingthe outer border of the speed dial (this wider part is called the hook). Whenthe train is in the TSM and the trainspeed is within the indication limit, the partabove V-target is shown in yellow.


20/113



If the trainspeed is more than V-permitted, the CSG between the hook (V-permitted) and V-intervention is also shown. This part of the CSG has thesame width as the hook.

The CSG shall follow the DMI colour philosophy.

5.2.1.5 Maximum speed indication


This DMI object displays supervised maximum speed (e.g. line speed) alongthe scale of the speed dial when ERTMS/ETCS is not in Full Supervision.


The maximum speed indication shall be displayed in area B2.The area size is 5 x 21 cells (w x h).

5.2.1.5.4 Example

Figure 17 Maximum speed indication


The supervised maximum speed is shown permanently when ERTMS/ETCSis not in FS. It is shown as a single line in a grey colour. It has the same sizeand shape as the hook from the function described in clause 5.2.1.4.Upon request of the driver the supervised maximum speed may besuppressed.Informative remark: this maximum speed should not be confused withpermitted speed.

5.2.1.6 Set speed indication


The set speed is displayed close to the CSG around the speed dial. The setspeed is directly related to what is known as the speed set control in certaintypes of trains.


The set speed indication shall be displayed in area B2.Diameter of the round set speed indication marker shall be at least 10 cells.The final form may differ if it stays within these margins.

Figure 19 Set speed indication


If the train can provide the information for the set speed, it is shown as around marker at the end of the scale markers.The marker is white. A black outline of 1 cell may used to clearly mark theborder of the set speed indication.

5.2.1.7 Release speed


This DMI object shows, digitally and in the CSG, the release speed ifavailable.


The release speed shall be on screen location B2 and B6.

The area size for digital release speed in B6 is 36 x 36 (w x h) cells.


23/113



The size of the release speed gauge in the CSG (see also clause5.2.1.4) is 4cells, the remaining part of the CSG is for V-permitted (app. 4 cells).

Figure 20 Screen location of the release speed

5.2.1.7.3 Examples

a. V-permitted > V-train

Current train speed: 20 km/h;Permitted speed: 50 km/hRelease speed: 26 km/h

b. V-permitted < V-train

Current train speed: 19 km/h;Permitted speed: 9 km/hRelease speed: 26 km/h

Figure 21 Release speed


The V-release speed shall be displayed in B6 as a digital number in mediumgrey (character height minimum 17 cells). The number is only shown when thetrain is in the TSM and the value is larger than 0 km/h.

When there is a release speed and the train is in the TSM,the release speedshall also be shown by the outer half of the CSG being filled with medium greyfrom its start to the release speed (see Figure 21a). The medium grey colour


24/113



is separated from the yellow colour of the CSG by a thin (1 cell) line in thebackground colour of area B.

When V-permitted is below the release speed, the hook remains shown at V-

permitted (see Figure 21b).

5.2.1.8 Advice speed


If available an advice speed may be displayed to the driver.


The Advice speed should be on screen location C2/3/4.

The area size is 105 x 50 (w x h) cells.

Figure 22 Screen location for advice speed

5.2.1.8.3 Symbols and audible information

The symbols 4.1 and 4.2, see Part 5, can be used depending on the advice.Sound S8, see Part 6, can be used depending on the current train speed (seeclause 4.2).


25/113



5.2.1.8.4 Example

Figure 23 Advice speed


If available an advice with regard to the speed can be given to the driver inC3. The reason for this advice may be shown in C4 (e.g. because of thetimetable, energy efficiency, a general advice from the Railway ManagementSystem, an advisory brake curve or advisory speed by the display of a

symbol). Each advice type has its own symbol.

The advice itself can be a remark that the train is driving too slow, too fast orshould coast, but also a specific speed (in the other cases).

In the case of an advice speed, the number is displayed to the driver togetherwith an arrow indicating how much (not exact, but relatively) the current speedmust be increased or decreased in C2. If the current train speed is higher thanthe advice speed the arrow points downwards, otherwise it points upwards.The arrow consists of a number of segments (5). The larger the differencebetween advice speed and the current train speed, the more segments are

shown (e.g. 2 km/h -> 1 segment, 5 km/h -> 2 segments, 10 km/h -> 3segments, 20 km/h -> 4 segments and >25 km/h -> 5 segments).The arrow is shown in a grey colour.

It is recommended not to show a speed advice when the train is in the TSM.

When a time table is available, this can be visualised by activating thecorresponding function:on a touch screen device by touching the C2/C3/C4 will activate the display ofthis table in the E19-25 area;when using soft keys after activating the dedicated key.

5.2.2 Brake Information

5.2.2.1 Distance to target


This DMI object shows the remaining distance to target).The target distance is shown as a straight bar.


The distance to target shall be displayed in area A2.The area size is 54 x 222 (w x h) cells.Maximum size of the bar is 10 x 172 (w x h) cells.

Figure 24 Screen location for distance to target

5.2.2.1.3 Example


27/113



Figure 25 Distance to target


A vertical rectangular bar shall be drawn on the right hand side of the area A2,indicating the remaining distance to the target. This distance shall only bedrawn when the train is in the TSM. The larger the distance to the target, thelarger the bar will be. There is however a maximum distance of 1000 metersthat is displayed graphically. Distances above 1000 meters are shown withnumbers (must be able to show 5 digits) above the bar; the bar is never longerthan that representing 1000 meters.A logarithmic distance scale is used. The interpolation between 0 and 100meters is linear, because it is not possible to display distances close to zerowith a pure logarithmic scale.The colour of the bar shall always be grey. The distance will also be shown in

digits in the same colour. The digital distance is shown in a number dividableby 10 and shall be positioned above the vertical bar.

5.2.2.2 Warning time to intervention


This DMI object shows to the driver a warning that an unwanted situation (e.g.an intervention) might occur. The warning indication dimension is dependenton the predicted time and distance to intervention.

Note: The information is particularly useful when the driver needs to anticipatemore then in average situations, e.g. freight trains, poor weather conditions,etc. In those cases the warning time to intervention helps to avoid interventionin an effective, not too demanding (conspicuous) presentation.


The warning time to intervention shall be displayed in area A1.The maximum size of the area is 54 x 54 cells (w x h).

Figure 26 Screen location for warning time to intervention


28/113



5.2.2.2.3 Example

Figure 27 Warning time to intervention

5.2.2.2.4 Display requirements

The warning time to intervention shall be drawn as a square in the top leftcorner of the screen.

Conditions for display:The behaviour of the square depends on the acceleration or deceleration ofthe train in combination with the intervention speed. Given the maximumacceleration of the train, ERTMS is calculating the time before intervention. Ifthis time (Tsquare) is within a certain range (e.g. 8 sec for passenger trains and20 sec for freight trains) the square shall be displayed.When the train is in TSM, the square is always displayed.When the train is in CSM, the square is only displayed if it meets the Tsquarecondition.

Square dimension:The size of the square depends on the predicted time to an intervention.When the train is in the TSM, the square is always displayed with at least acertain minimum size (10% of its largest possible size: 5 x 5 cells). As soon asthe predicted time to an intervention is below a certain value (e.g. Tsquare) inTSM, the square will start to grow until it reaches its maximum size (= time tointervention is zero). This means the closer the predicted intervention, thelarger the square.

The square is full size when the time to intervention is zero (50 x 50 cells).When the time to intervention is larger then Tsquare, the square shall be


29/113



invisible (size 0) in CSM, and shall have its minimum in TSM. In between thesize is increasing linear, but the square shall only change its size in 4 steps:full interval (Tsquare_max; small), half interval (Tsquare_1/2max; 1/2 size), 1/4interval (Tsquare_1/4max; 3/4 size) and no interval left (= 0 sec) (full size).

The size of the square is calculated dynamically and follows the dynamicbehaviour of the train.

Square colour:The colour of the square is following the colour coding principle for indication,warning and intervention.

5.2.2.3 Predicted distance to standstill location


This DMI object shows the predicted distance to the standstill location inrelation to the distance to target.


The predicted distance to standstill location shall be displayed in area A2.The area size shall be 54 x 222 (w x h) cells.Maximum size of the bar shall be 10 x 172 (w x h) cells downwards and 10 x20 (w x h) cells upwards.


30/113



Figure 28 Screen location for predicted distance to standstill location

5.2.2.3.3 Example

Figure 29 Predicted distance to standstill location


A vertical rectangular bar should be drawn on the left-hand side of the areaA2, indicating the predicted distance in which the train will come to a standstill.This bar shall only be drawn when:

the current target has a target speed of 0 km/h, and

the train is in the TSM , and

the brakes have been applied manually at least once in the

TSM.


31/113



the current train speed is above a certain value (e.g. 10 km/h).

The bar always originates at the target distance. If the predicted distance tothe standstill location is beyond (in advance of) the target distance the top of

the bar is calculated by adding a fixed amount of cells (20 cells on a 640 x 450grid array) and is shown in orange. These added cells can also be seen at thefull scale of the bar at the target distance.

Otherwise, if the predicted standstill location is in rear of the target distance(the train is predicted to stop too soon) the bottom of the bar is derived fromthe predicted distance to the standstill location and shall be shown in grey.

However, when the predicted standstill location is the same as the targetdistance, a line of 1 cell thick is drawn.

5.2.2.4 Predicted speed at target


This DMI object shows the predicted train speed at the target location inrelation to the target speed.


The predicted speed at target should be displayed in area A3.The area size shall be 54 x 24 (w x h) cells.

Figure 30 Screen location for predicted speed at target


32/113



5.2.2.4.3 Example

Figure 31 Predicted speed at target


A rectangle with two coloured areas should be displayed. This rectangle issliding in an area with a window in the middle. The window indicates howmuch the predicted train speed at the target location is higher or lower thanthe target speed.

The colour of the left side of the slider should be grey and on the right sideshould be orange. The slider should not move so far to the left or right suchthat one of the colours is no longer visible; a margin of 2 cells should remainvisible.

The sliding rectangle should only be shown when:

the brake target speed is higher than 0 km/h , and

the train is in the TSM, and

the brakes have been applied at least once in the TSM or thetraction is cut-off at least once in the TSM.

34/113




A symbol is displayed which indicates that the train is applying a service oremergency brake intervention. When there is no intervention, no symbol isshown. There are two different symbols: one for the service brake interventionand one for the emergency brake intervention.

If the intervention must be acknowledged by the driver, before the interventioncan be cleared, the symbol will start to flash when the intervention couldsafely be stopped. At the same moment sound S3 shall be executed.

When using a touch screen device, area C9 may be activated while thesymbol is flashing to acknowledge the intervention.

When using soft keys the dedicated softkey (could also be the symbol itself)

may flash to indicate which key should be activated to acknowledge theintervention.

In the case where both interventions occur at the same time the DMI shallonly show the emergency brake.Once the most restrictive intervention has been acknowledged or released theremaining one, if still activated, shall be shown.

The area shall consist of at least five visible lines of text, which are used for

incoming and outgoing messages. It shall be possible to scroll the list ofmessages. A message is displayed with a time stamp and the message itself.


42/113



It should be avoided to present messages longer than one line. If a messageis longer than one line it will continue on the next line, but it shall be madeclearly visible to which message the second line belongs (see Figure 41).The text messages are classified in a chronological way and the newest

displayed message shall be at the top of the E19-E23 area. The newest of alldisplayed text messages should be displayed in E19.To scroll through the list of messages the upper right corner (E24) isdedicated to scroll up in the list, the lower right corner (E25) is dedicated toscroll down in the list.

The outgoing messages can appear in a list and can be examined using thenormal procedure.

This area E19 E25 is also used as second layer for area C and it will also beused during driver entry. However, information to be acknowledged can not be

hidden by second layer information of area C.

It is recommended, to gain space for text messages, to integrate areas E24and E25 within the fields of areas E19 to E23, as explained above.

5.2.3.4.5.2 Requirements only applicable to text messages that have notto be acknowledged

A new informative message will be presented in white colour; a short sound(S7) should accompany the new incoming message. After a certain time(Tmess) the message is presented in grey.

5.2.3.4.5.3 Requirements applicable to text messages to beacknowledged

A message to be acknowledged is presented alone (the other messages aretemporarily not shown) in the E19-E25 area in white with a flashing yellowframe around the text area. After acknowledgement the message colour willbe grey and the frame disappears.Messages to be acknowledged at the same moment shall be acknowledgedone by one; otherwise the message remains with the flashing frame.

When using a touch screen device, after having touched somewhere on thearea E19 - E25 the receiving message is acknowledged and the flashingyellow frame will disappear and the corresponding message should bedisplayed as other text messages (in grey) or deletedFor acknowledgement the whole area is activated. The message list can onlybe hidden or switched off (not if acknowledgement is active) after a touch onthe top left corner of the area (size 50 x 50 cells) or when the display of thetimetable is requested. It can not be switched off as long as a message to beacknowledged awaits acknowledgement. The top left corner of the area isonly activated after the acknowledgements of all ack- or warning messages.

Figure 43 Actual orders


When an order requires an action by the driver or by the ERTMS/ETCSsystem, the ETCS-DMI shall indicate the driver when the order becomesactual. The definition of actual depends on whether the order should beexecuted within a certain distance or time before the event occursWhen an action is required by the driver, it will be displayed in yellow with aflashing yellow frame around it. When the action will be performed by the

system it will be displayed in grey.

When the action is performed correctly, the flashing will stop.The order or announcement symbol will be removed from this area after theevent has occurred (e.g. end of tunnel) or when the event has started (at themoment the front end of the train passes the location of the order orannouncement, e.g. lower pantograph). When the appropriate action is notperformed correctly the symbol is shown in red with a non-flashing red framearound it and remains in this area until the reason for the order hasdisappeared.

The placement of the actual orders and announcements is from left to rightfilling B3/4/5. When an area is already taken, the next area is checked. Whenall areas are already taken, a waiting list should be created.

one time. This means that two orders/announcements or speed relatedtargets (see clause 5.3.4) can not display second layer information at thesame time.

Symbols are distributed over the three columns to avoid overlapping as muchas possible. A symbol is classified depending on the distance. Two adjacentsymbol are not placed into the same column but within the next one.

The announcement symbol shall be removed as the front of the train passesthe announcement location. However, if a distance is specified for theannouncement, the symbol shall remain until the whole train has covered therequired distance.

Announcement symbols are shown in grey, except for orders where an actionis required by the driver the symbol will be shown in yellow. When the action

is performed by the system the colour of the symbol shall return to grey.

When the appropriate action is not performed correctly (by driver or bysystem) the symbol shall be shown in red.

The order symbols shall also be shown in the B3/4/5 area (see clause 5.2.3.1)a specified time (Tactual) before the action location is reached,.

The speed shall not be presented to scale, but with fixed ratios relative to thecurrent speed profile (1/1). Speed decreases are shown as 3/4, 1/2 or 1/4 ofthe current line speed and a speed of zero is displayed as zero. Each time aspeed decrease is effective, the width of the diagram shall be shorten by of

the full width (corresponding to the current maximum ceiling speed). Anexample: if the current maximum ceiling speed of the speed profile is 140km/h and the first speed reduction is 70 km/h, then the speed profile in D7shows a reduction to 3/4 of the current maximum; if the next speed reductionis 40 km/h, then the speed profile in D7 shows 1/2 of the current maximum(e.g. 140 km/h).

In case of a TSR, when the speed beyond the restriction is higher then thecurrent current maximum ceiling speed shall not be shown within D7 area.The displayed speed profile shall filter out speed increases from the MRSP (itshall be indicated when this higher speed level becomes the current maximum

ceiling speed).

The front end to be used for MRSP calculation is defined in the SRS.

D DATA ENTRY FOR THE ERTMS/ETCS/GSM-R

SYSTEMS

4 Data Entry general principles

Section 4.3 Default data

To facilitate the data entry, a default value shall be presented to the driver if itis available.

Once the input field becomes selected, the default value (if any) shall beshown selected to the driver. Subsequently, the driver shall have two

possibilities:

To accept the default value by activating the corresponding [Enter]button,

To erase the whole default value by typing any newcharacter/selecting a new value or the [Delete] button.

If the default value is not available, an empty input field shall be presented tothe driver.

For further details on input fields, one will refer to Part 1 of this standard.

Section 5 Data windows

This standard (Part 4) describes the data entry dialogue in terms of windowsto be used. It does not prescribe the order in which the different windows arepresented to the driver. This is defined by the ERTMS/ETCS system.

For data entry windows, the following description of the areas is based on

definition of Part 1 and Part 2 for areas:


77/113



Eleft

O

Eright+

F6,F7,F8,F9

Figure 1 General overview screen location

Figure 1 shows the DMI when all information is combined into one screenwindow. If not all areas are available for data entry, the areas shall becombined on to the available screen window.

Area M has the same size as area A plus area B plus area C.

Area N has the same size as area D plus area F1 to F5.

Depending on the technical solution area N can be combined with area M.

Area O has the same size as area Eright plus area F6 to F9.

If the train is not moving, areas M, N and O can be used all together and shallbe called area P.

It should be noted that in the examples shown in this standard, a touchscreendevice for data entry is assumed.

5.1 Data entry/change window

There are two types of data entry/change windows:

A window that allows data entry operations while the train ismoving.

A window covering the whole grid array (area P), to perform dataentry operation at standstill.


78/113



Note: Whether or not the use of data entry windows is allowed while thetrain is moving is out of the scope of this standard.

5.1.1 Full window for data entry/change

5.1.1.1 Description

This data entry window provides the possibility to enter data, which requiregreat attention from the driver. It gives a good feedback to the driver of whathas been taken into account by the trainborne system.

5.1.1.4 Display requirements

5.1.1.4.1 Window label

A window label area shall be indicated in the top of area M.

The window label area shall cover the whole width of area M.

The height of the title area shall be at least 24 cells.

The window label area shall be black.


79/113



The window label area shall contain a label, which shall clearly indicate to thedriver which kind of data is requested to be entered.

The window label is aligned to the right of the area.

The window label shall be grey placed on black background.

5.1.1.4.2 Input fields area

The input fields for each of the data to be entered/changed and accepted bythe driver shall be presented in a column within area N.

The column delimitation shall be not visible.

If the number of data to be entered within the same data entry step (N_step) ishigher than the number of data input fields that can fit on to a single data

entry/change window (N_window), the input fields shall be presented onseveral data entry/change windows.

Note: If N_step >N_window then there shall be several data entry/changewindows.

It shall be possible, in this case, to navigate between the different data entrywindows by using the [Previous], [Next] control buttons.

The selected input field shall be shown highlighted.

Within the input field, the state of the data items shall be presented by meansof a different colour of the data value depending on the data state:

a white colour of the value for already accepted data (acceptedstate),

a grey colour for not yet accepted data (not accepted state).

Note: By this colour coding of the data value (if any), it shall be clear to thedriver which data has still to be entered/changed and accepted and whichdata the driver has already entered/changed and accepted.

5.1.1.4.3 Data feedback area


80/113



Input field labels shall be repeated within the area M for all the data that canbe entered by the driver during the current data entry step. The input fieldlabel shall be called data label later on in this standard. The list shall presentthe whole set of data label belonging to the data entry step even if there are

several data entry/change windows for the same data entry step.

Note 1: By this full list of data, the driver knows what data is expected to beentered.

Note 2: This implies that if there are several data entry windows, datafeedback area shall be the same for all the data entry windows belonging tothis data entry step.

While the corresponding data is not yet accepted by the driver, no data valueshall be presented and the data label shall be grey. This corresponds to the

non-accepted state of the data.
