SIST EN 16286-1:2013
EN 16286-1:2013 (E) 5 Introduction The railway system requires technical rules for train concepts with flexible connections which allow passage from one vehicle to the next vehicle (or between vehicle modules). This standard describes main requirements for the design and validation of gangway systems. The requirements set out in this standard are based on long-term existing practices and procedures developed and currently in use by railway undertakings and industry. The application of these systems has changed over the years.
For many years the majority of gangway systems consisted of rubber tubes pressed together when coaches were coupled. This solution is standardized in UIC leaflet 561 with the aim to reconfigure train sets. Main requirements of this leaflet have been incorporated in this standard as Annex A. UIC Leaflet 561 is to date the only reference document available, but does not cover project specific solutions, which have been developed for each train set; for example, for multiple units, metros or tramways. The aim of EN 16286-1 is to close this gap and to cover the complete range of gangway systems.
SIST EN 16286-1:2013EN 16286-1:2013 (E) 6 1 Scope This European Standard defines the technical and safety requirements applicable to gangway systems used in all railway vehicles such as tram, tram trains, coaches, metro, suburban, main line and high speed trains that carry passengers. A gangway system gives comfortable passage from one vehicle to the other and consists of a flexible component which allows relative movement between vehicles. It also defines: the requirements for the safety for passengers and/or staff in the gangway while the train is running;
the assessment methods as well as pass/fail criteria for gangways installed on vehicles. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

This system accommodates all relative movements between the two vehicles by its design and allows the passage from one vehicle to the next vehicle. It protects passengers and staff from falling out of the train and protects against external environmental conditions.
SIST EN 16286-1:2013EN 16286-1:2013 (E) 14 Additional features may be added according to the specification. Flange intercommunication connections are specific types of intermediate gangways, typically used for coaches and vans. They are described in Annex A.
5.2 Environmental resistance The design of gangways shall take into account the environmental conditions to which they will be subjected.. Environmental parameters, described in EN 50125-1, shall be considered in the specification for the gangway. 6 Vehicle body coordinate system The coordinate system is shown in Figure 8. The positive direction of the x-axis (corresponding to vehicle body longitudinal axis) is in the direction of movement. The positive direction of the z-axis (corresponding to vehicle body vertical axis) points upwards. The y-axis (corresponding to vehicle body transverse axis) is in the horizontal plane completing a right hand coordinate system. NOTE Conventional coach pictured, but gangways can also connect modules of a multi-moduled vehicle typically in tram applications.

SIST EN 16286-1:2013EN 16286-1:2013 (E) 15 7.2 Weight
The maximum weight of the gangway system should be defined in the specification.
NOTE System architecture, dimensional and acoustic requirements have an important influence on the weight.
7.3 Geometry 7.3.1 Outer gangway dimensions The outer gangway dimensions shall respect the vehicle gauge. 7.3.2 Clearway The volume as shown in Figure 9 shall be maintained as clearway over the length of the gangway as well as in associated gangway doors measured on straight and level track.
The horizontal clearway shall maintain a minimum of 550 mm.The vertical clearway shall maintain a minimum of 1 950 mm.
Where the infrastructure (gauge or vehicle profile) does not allow this, an exception may be accepted by the authorities for both values. NOTE For front end gangway systems, the essential requirement for drivers' sight line in combination with small vehicle profiles might necessitate a reduction of these values.

EN 16286-1:2013 (E) 16 7.3.3 Clearway for wheelchairs Passage of wheelchairs through the gangway may be required as an option. This option is taken into account for certain vehicle architecture, for example, for escape routes and access to toilet facilities.
The volume as shown in Figure 10 shall be maintained as clearway over the length of the gangway, as well as in associated gangway doors under each service condition, e.g. curves. In addition to 7.3.2, the horizontal clearway for wheelchairs shall maintain a minimum of 800 mm up to a minimum height of 1 450 mm.
Dimensions in millimetresKey 1 TOF 2 gangway shape x length of the gangway Figure 10 — Volume representing the clearway between connected vehicles for wheelchairs 7.3.4 Length The length of the gangway shall be chosen in such a way that the gangway has the capability to allow all relative movements of the vehicle.
7.3.5 Steps and ramps Discontinuities within the floor transition from one vehicle to the gangway, as well as from the gangway to the connected vehicle, should be minimised to facilitate passage without trip and stumble hazards. Sudden height changes shall be less than 15 mm high in nominal position and have chamfered or rounded edges. Ramps up to a length of 600 mm shall not exceed a maximum gradient of 10,2° (18 %).
Ramps with a length from 600 mm to 1 000 mm shall have a maximum gradient of 8,5° (15 %). Ramps with a length more than 1 000 mm shall have a maximum gradient of 4,47° (8 %).
SIST EN 16286-1:2013EN 16286-1:2013 (E) 17 7.4 Relative movements Maximum movements shall be defined in the specification. The particular conditions (service or depot) shall be considered.
During design, movement studies with the relevant and extreme movements shall be carried out for service and depot conditions.
NOTE 1 In depot conditions, interior safety requirements can be relaxed considering that no passengers but trained staff can be present. A movement study shall be carried out to ensure that the gangway system performs all required movements without any damage. The requirements described in 7.3 and 7.5.3 shall be verified.

7.5 Load requirements 7.5.1 General Any flexible elements (e.g. skirts), used on the floor and sides shall be strong and stiff enough to provide safe support to passengers and staff. 7.5.2 Vertical load applied to bridge system
Loading capability of the floor may be demonstrated by calculation or test. A static passenger load according to EN 15663 and applicable accelerations according to EN 12663-1 on the floor area of the bridge system shall be taken into account for service condition.
The bridge system shall withstand a static load of 800 N applied over a surface of 100 mm x 200 mm at any point of the bridge system. Additional, special loads may be defined in the specification.
The relevant acceptance criteria according to EN 12663-1 are: to verify the strength of the structure when subjected to the maximum loads; to verify that no significant permanent deformation is present after removal of the maximum loads.
7.5.3 Dynamic loads on gangway system and fixation Accelerations, defined in EN 12663-1 for equipment attachments, as well as forces generated by the relative movements shall be taken into account.
7.5.4 Horizontal loadThe gangway sidewall of the clearway shall carry a load simulating a person leaning against the sidewall. Concentrated perpendicular loads acting from within the gangway shall be applied without causing any permanent deformation:
a load of 15 % x 80 kg x 9,81 m/s2 = 120 N representing a hand of a person over an area of 0,1 m x 0,1 m on any area of the surface of the gangway; a load of 80 kg x 9,81 m/s2 = 800 N representing the shoulders of a person over an area of vertical extension of 0,2 m
and a horizontal extension of0,5 m cent
