What is BS EN 17355 about?
BS EN 17355 defines the following elements for urban rail rolling stock:
- The functional requirements for a communication device between passengers and driver or operations control centre (OCC)
- The dynamic behaviour of the communication device.
BS EN 17355 is applicable to the categories I to III of urban rail rolling stock defined in CEN/CLC Guide 26:
- (I) Metros
- (II) Trams
- (III) Light Rail.
NOTE: BS EN 17355 applies to urban rail rolling stock both with and without the driver.
NOTE: CEN/CLC Guide 26 defines metro, tram and light rail as public transport systems permanently guided at least by one rail, intended for the operation of local, urban and suburban passenger services with self-propelled vehicles and operated either segregated or not from the general road and pedestrian traffic.
NOTE: The communication device is different from the PAS, but it can share some parts of the PAS to achieve its functionalities.
NOTE: The PAS is regarded as a safety-relevant system whereas the communication device is non-safety relevant aid to passengers.
Who is BS EN 17355 for?
BS EN 17355 on railway communication devices is useful for:
- Railway engineer
- Railway driver or operations control centre (OCC)
Why should you use BS EN 17355?
A communication device for urban rail is a system used to enable passengers to speak with authorized railway persons.
BS EN 17355 gives you the information on communication device interfaces and an overview in order to show an example of who is involved in the communication device operation.
Also, an overview of the event in sequence flowchart for the communication device operation is given in this document.
BS EN 17355 also provides the requirements on the communication device interface design and communication priority requirements.
As a result, BS EN 17355 assists railway operators in notifying passengers of any exceptions or changes to the train or metro service, coordinating evacuations and/or station closures in the event of a security crisis, and guaranteeing safe shunting operations.
