Railway applications - Driver's cab - Part 4: Layout and access

This document gives design rules and requirements in order to ensure proper access, lighting, seating and exit of the driver’s cab. The different dimensions are based on the anthropometric data defined in EN 16186-1. The corresponding assessment methods are also included in this standard. It covers the following aspects:
-   dimension and interior layout;
-   door access, steps, floor characteristics;
-   seats dimension and clearance;
-   interior cab lighting;
-   emergency exit;
-   marking and labelling.
This part of the EN 16186 series applies to driver’s cabs of Electrical Multiple Unit (EMU), Diesel Multiple Unit (DMU), Railcars, Locomotives and Driving trailers (Driving Coaches).
NOTE 1   This European Standard applies to rolling stock in the scope of Directive 2008/57/EC [6].
This part of the EN 16186 series applies to driver's desks installed on the left, on the right, or in a central position in the driver’s cab. Due to cab space and resulting desk integration constraints, desk layout can vary.
NOTE 2   Due to railway systems constraints, the level of comfort and accessibility provided to the persons outside the anthropometric range defined in EN 16186-1 may vary. Usually the operators manage the potential restrictions, if the driver uses the full range of seat positions (as defined in this standard) combined with extreme body dimensions (as defined in EN 16186-1).
This document is not intended to be applicable for OTMs, tramways, metro and light rail vehicles.
NOTE 3   For OTMs, see EN 14033-1 [11] and EN 15746-1 [17].

Bahnanwendungen - Führerraum - Teil 4: Gestaltung und Zugang

Dieses Dokument enthält Gestaltungsregeln und Anforderungen, um eine angemessene Ausführung von Zugang, Beleuchtung, Sitzen und Ausstieg aus dem Führerraum sicherzustellen. Die unterschiedlichen Maße basieren auf den in EN 16186 1 festgelegten anthropometrischen Daten. Diese Norm enthält zudem die entsprechenden Bewertungsverfahren. Sie deckt die folgenden Aspekte ab:
—   Abmessung und Innenraumgestaltung;
—   Türzugang, Stufen, Fußbodeneigenschaften;
—   Sitzabmessungen und Freiräume;
—   Beleuchtung im Inneren des Führerraums;
—   Notausstieg;
—   Kennzeichnung und Beschriftung.
Dieser Teil der Normenreihe EN 16186 gilt für Führerräume von elektrischen Triebzügen (EMU), Dieseltriebzügen (DMU), Triebwagen, Lokomotiven und Steuerwagen.
ANMERKUNG 1   Diese Europäische Norm gilt für Schienenfahrzeuge im Anwendungsbereich der Richtlinie 2008/57/EG [6].
Dieser Teil der Normenreihe EN 16186 gilt für Führertische, die links, rechts oder mittig im Führerraum angeordnet sind. Aufgrund der Führerraumgröße und der dadurch bedingten Einschränkungen bei der Integration des Führertisches kann die Gestaltung des Führertischs variieren.
ANMERKUNG 2   Aufgrund von Einschränkungen bei den Eisenbahnsystemen kann der Komfort und Zugang, der Personen außerhalb des in EN 16186 1 definierten anthropometrischen Bereichs geboten wird, abweichen. Für gewöhnlich regeln die Betreiber den Umgang mit potenziellen Einschränkungen für den Fall, dass Triebfahrzeugführer das gesamte Spektrum an Sitzpositionen (wie in dieser Norm definiert) einnehmen und gleichzeitig extreme Körpergrößen (wie in EN 16186 1 definiert) haben.
Dieses Dokument gilt nicht für OTMs, Straßenbahnen, U-Bahnen und Stadtbahnen.
ANMERKUNG 3   Zu OTMs siehe EN 14033 1 [11] und EN 15746 1 [17].

Applications ferroviaires - Cabine de conduite - Partie 4 : Aménagement et accès

Le présent document spécifie les règles de conception et donne des exigences pour optimiser la cabine de conduite en termes d'accès, d'éclairage, d'assise et de sortie. Les différentes dimensions s'appuient sur les données anthropométriques définies dans l'EN 16186-1. Les méthodes d'évaluation correspondantes sont également fournies dans cette norme. La présente norme couvre les aspects suivants :
-   dimensions et agencement intérieur ;
-   caractéristiques de l'accès aux portes, des marchepieds et du plancher ;
-   dimensions et espaces libres concernant les sièges ;
-   éclairage intérieur de la cabine ;
-   issue de secours ;
-   marquage et étiquetage.
La présente partie de la série EN 16186 s'applique aux cabines de conduite de Rames Automotrices Electriques (EMU), de Rames Automotrices Diesel (DMU), d'autorails, de locomotives, ainsi qu'aux voitures-pilotes.
NOTE 1   La présente Norme européenne s'applique au matériel roulant relevant du domaine d'application de la directive 2008/57/CE [6].
La présente partie de la série EN 16186 s'applique aux pupitres de conduite, qu'ils soient installés à gauche, à droite ou au centre dans la cabine de conduite. L'agencement du pupitre de conduite peut varier selon l'espace disponible dans la cabine et les contraintes d'intégration qui en résultent.
NOTE 2   En raison des contraintes des systèmes ferroviaires, le niveau de confort et d'accessibilité fourni aux personnes situées en dehors de la plage de données anthropométriques définie dans l'EN 16186-1 peut varier. Habituellement, les opérateurs gèrent les restrictions potentielles, si le conducteur utilise toute la gamme des positions du siège (telles que définies dans cette norme) en combinaison avec des dimensions du corps extrêmes (telles que définies dans EN 16186-1).
Le présent document n’est pas censé s'appliquer aux tramways, métros et autres véhicules ferroviaires légers.

Železniške naprave - Voznikova kabina - 4. del: Postavitev in dostop

Ta evropski standard določa pravila oblikovanja in smernice za zagotovitev ustreznega dostopa do voznikove kabine, razsvetljave v njej, sedeža in izstopa iz nje. Različne dimenzije temeljijo na antropometričnih podatkih, opredeljenih v standardu EN 16186-1. V ta standard so vključene tudi ustrezne metode ocenjevanja. Zajema naslednje vidike:
– dimenzije in notranjo postavitev;
– dostop do vrat, stopnice, značilnosti tal;
– dimenzije in prostornina sedežev;
– notranja osvetlitev kabine;
– izhod v sili;
– označevanje in etiketiranje.
Ta del skupine standardov EN 16186 se uporablja za voznikove kabine električnih vlečnih vozil (EMU), dizelskih vlečnih vozil (DMU), vagonov, lokomotiv in vlečnih prikolic (vlečnih vagonov).
OPOMBA 1:   Ta evropski standard se uporablja za tirna vozila, ki spadajo na področje Direktive 2008/57/ES [6].
Za tirna vozila glejte standarda EN 14033-1 [12] in EN 15746-1 [18].
Ta del standarda EN 16186 se uporablja za voznikove mize, ki so nameščene na levi ali desni strani ali sredi voznikove kabine. Zaradi prostora v kabini in posledičnih omejitev pri vgradnji miz se lahko postavitve miz razlikujejo.
OPOMBA 2:   Zaradi omejitev železniških sistemov se raven udobja in dostopnosti za osebe zunaj opredeljenega antropometričnega razpona, določenega v standardu EN 16186-1, lahko razlikuje. Običajno upravljavci obvladujejo morebitne omejitve, če izjemno visok voznik uporablja skrajne položaje sedeža.
Ta standard se ne uporablja za tramvaje, metroje in lahka železniška vozila.

1 Scope

This document gives design rules and requirements in order to ensure proper access, lighting, seating

and exit of the driver’s cab. The different dimensions are based on the anthropometric data defined in

EN 16186-1. The corresponding assessment methods are also included in this standard. It covers the

following aspects:
— dimension and interior layout;
— door access, steps, floor characteristics;
— seats dimension and clearance;
— interior cab lighting;
— emergency exit;
— marking and labelling.

This part of the EN 16186 series applies to driver’s cabs of Electrical Multiple Unit (EMU), Diesel

Multiple Unit (DMU), Railcars, Locomotives and Driving trailers (Driving Coaches).

NOTE 1 This European Standard applies to rolling stock in the scope of Directive 2008/57/EC [6].

This part of the EN 16186 series applies to driver's desks installed on the left, on the right, or in a

central position in the driver’s cab. Due to cab space and resulting desk integration constraints, desk

layout can vary.

NOTE 2 Due to railway systems constraints, the level of comfort and accessibility provided to the persons

outside the anthropometric range defined in EN 16186-1 may vary. Usually the operators manage the potential

restrictions, if the driver uses the full range of seat positions (as defined in this standard) combined with extreme

body dimensions (as defined in EN 16186-1).

This document is not intended to be applicable for OTMs, tramways, metro and light rail vehicles.

5.1.1 General
5.1.1.1 Access and security

Access to the driver’s cab shall be from the exterior via a direct external door, or through an adjacent

compartment or area behind the cab.

These doors shall be designed to have an operational envelope that does not conflict with the envelope

of another cab access door.
---------------------- Page: 10 ----------------------
SIST EN 16186-4:2019
EN 16186-4:2019 (E)

The driver’s cab and its access shall be designed so that the train crew is able to prevent the cab being

accessed by non-authorized persons, whether the cab is occupied or not. This requirement is deemed to

be fulfilled by a locking system.

A cab door locking system shall permit to open any cab door from inside the cab without using any tool

or key.

Egress and access to the driver’s cab shall be possible without any energy supply.

5.1.1.2 Door handles

Driver’s cab internal door handles which are intended to be operated from a standing position shall be

located at a height between 820 mm and 1 200 mm (distance between the rotation point of the handle

and the cab floor). The recommended value for the height of the door handles is 850 mm.

5.1.1.3 Threshold
The height of door threshold shall not be more than:
— 20 mm from the walkable floor for interior doors excluding locomotives;
— 70 mm from the walkable floor for interior doors of locomotives;
— 60 mm from the walkable floor for exterior doors.
5.1.1.4 Ergonomics

For interior handles in regular use at least 40 mm clearance to surrounding surfaces shall be provided.

For exterior handles see EN 16116-1.
5.1.2 External doors
External doors and hand holds shall be designed in accordance with EN 16116-1.

Dimension r shall have a maximum value of 20 % of the width.

Driver’s cab front facing external doors which are positioned left or right of the vehicle’s longitudinal

axis and open in longitudinal direction may have a trapezium shaped upper area with an angle of the

top outer side. In order to achieve a maximum passage width in the angled upper area of the door, the

maximal construction gauge shall be used to its full extent. This reduction due to the gauge calculation

shall keep a minimum clearance width of 280 mm in the upper area (see Figure B.2).

Cab external doors shall not open unintentionally. External cab doors should have at least two stable

positions: fully open and closed.
5.1.3 Internal doors giving access to the driver's cab

If internal doors lead directly to the passenger area, a device to look from inside the cab shall be

provided, (e.g. by a spy hole).

If direct view from passenger area into cab is possible, the driver should be able to prevent such view,

e.g. by blinds.

Internal doors shall have a rectangular-like minimum unobstructed passage height and passage width

of 1 700 mm × 430 mm. Internal doors should have a rectangular-like minimum unobstructed passage

height and passage width of 1 950 mm (height) × 600 mm (width).

Internal doors which are positioned left or right of the vehicle's longitudinal axis and open in

longitudinal direction may have a trapezium shaped upper area with an angle of the top outer side

(see Figure B.3). In order to achieve a maximum passage width in the angled upper area of the door, the

maximal construction gauge shall be used as a common basis. This reduction due to the gauge

calculation shall keep a minimum clearance width of 280 mm in the upper area.
5.2 Floor and flooring
5.2.1 Floor surface criteria
Walkable floor surfaces shall be slip resistant.

This is deemed to be fulfilled by applying the requirements of CEN/TS 16165, α ≥ 9°.

shod

For minimizing the tripping hazard, the walkable floor of the cab, except for the area up to a maximum

of 25 mm from the walls and for the space under the desk, shall be level (see Figure 2).

B Walkable floor
Figure 2 — Walkable floor: admissible irregularities
This is deemed to be fulfilled by the following criteria:

— on a level track, the walkable floor shall be horizontal with a tolerance of ± 2° except for the

walkable floor areas determined to changes of height, and;
— no irregularity on the walkable floor shall protrude by more than 5 mm.

Door thresholds and foot operated operational elements are not considered as being a floor irregularity.

No deflection of more than 10 mm shall be permitted in the walkable floor, over an area of 5 000 cm ,

due to an applied load of 1 300 N on a surface of maximum 600 cm . This can be demonstrated by

calculation or by test.

NOTE No reference to EN 15663 is given, because the load is associated to the stiffness of the floor and not to

the load calculation for the vehicle.
5.2.2 Inclination, steps and slopes

The walkable floor of the driver's working area (access to the cab and foot rest excluded) shall be

without any steps. Height changes > 4 mm per 100 mm length are not permitted on the walkable cab

floor of the driver's working area. They are permitted between the cab and adjacent compartments.

Height changes of interior walkable floors between the cab and adjacent compartments ≤ 60 mm shall

be achieved by a sloping walkable floor. Height changes > 60 mm and < 120 mm should be avoided.

---------------------- Page: 13 ----------------------
SIST EN 16186-4:2019
EN 16186-4:2019 (E)

Height changes ≥ 120 mm shall be achieved by steps which shall have a height h with

120mm ≤ h ≤ 250mm and a depth of ≥ 210 mm. If more than one step is used the depth of the steps

shall be ≥ 270 mm. If there are two or more steps, a handhold (e.g. a handrail or a single handle) should

be provided.

Height changes > 60 mm and < 120 mm should be avoided (if not a single step should be added).

Where the change of height is achieved by a sloping walkable floor, the minimum length of the walkable

slope shall be 300 mm.
Steps immediately adjacent to slopes shall be prohibited.

Sealing plates of door frames and maintenance openings are not considered as being a floor irregularity.

5.3 Windows
5.3.1 Mechanical characteristics of glass

Where glass is used in glazing (including mirrors), it shall be either laminated or toughened glass which

is in accordance with a relevant national or international standard with regard to the quality and area of

use, thereby minimizing the risk to passenger and staff being injured by breaking glass.

5.3.2 Operation of opening windows
Three types of windows are considered in this standard:
— sliding horizontal;
— sliding vertical;
— hinged;

For easy moving upwards and downwards of vertical windows (e.g. to open, or to close) the operating

force should be less than 50 N and shall not be higher than 80 N.

For hinged windows, the operating force should not be higher than 62 N and for pulling not higher than

55 N.
For horizontally sliding windows, the operating force should not exceed 80 N.
5.4 Emergency
5.4.1 Driver's cab emergency exits
5.4.1.1 General

Driver's cab emergency exit and emergency exit clearance shall comply with the requirements of

EN 45545-4:2013, 4.3.1.2.

The lowest point of the emergency exit should be located at no more than 1 350 mm above cab floor

level.
5.4.1.2 Minimum escape route

An exit shall give access to an escape route of a minimum length of 2 m, of a minimum clearance of

height 1 700 mm x width 430 mm (if possible, width should be 600 mm). This escape route and its floor

shall be free of any obstruction; it shall be located on-board the unit, and can be an interior area or an

area opened to the outside. A single step is not c
