3 Terms and definitions
For the purposes of this document, the following terms and definitions apply. ISO and IEC maintain
terminological databases for use in standardization at the following addresses:

3.1
Urban Guided Transport (UGT) systems
system covering metro, tram and light rail, and defined 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 general road and pedestrian traffic
Note 1 to entry: Adapted from CEN-CENELEC Guide 26.
3.2
metro system
UGT system operated on its own right of way and segregated from general road and pedestrian traffic;
consequently designed for operations in tunnels, viaducts or on surface level but with physical
separation in such a way that inadvertent access is not possible
Note 1 to entry: In different parts of the world, Metro systems are also known as the underground, the subway
or the tube. Rail systems with specific construction issues operating on a segregated guideway (e.g. monorail, rack
railways) are also treated as Metros as long as they are designated as part of the urban public transport network.
Note 2 to entry: Adapted from CEN-CENELEC Guide 26.
3.3
tram
UGT system not segregated from general road and pedestrian traffic, which shares its right of way with
general road and/or pedestrian traffic and is therefore embedded in its relevant national road traffic
legislation (highway codes and specific adaptations)
Note 1 to entry: Adapted from CEN-CENELEC Guide 26.
3.4
light rail
UGT system operated on parts of the system not segregated from general road and pedestrian traffic,
and on parts of the system with segregated right-of-way. The segregation may include some sections of
line where inadvertent access is not possible
Note 1 to entry: Adapted from CEN-CENELEC Guide 26.
3.5
local rail system
system connecting city centres with their suburban hinterland or regional local centres, operated on
rights of way which are basically segregated from general road and/or pedestrian traffic and/or which
can be declared by law as independent from the public environment even if they are not segregated by
location, form of construction or appropriate measures
Note 1 to entry: Local rail systems, by national decision complying with Article 1.3 (a) or (b) of Directive
2008/57/EC, may be excluded from the European Community Rail System.
Note 2 to entry: For historical reasons local rail systems may be strongly influenced by conventional railway
parameters and their operations procedures.
Note 3 to entry: Adapted from CEN-CENELEC Guide 26.
3.6
tram/train
vehicle designed for combined use on both a tram or light rail infrastructure and a heavy rail
infrastructure
Note 1 to entry: Adapted from DIRECTIVE (EU) 2016/797.
3.7
vehicle
complete assembly of one or more cars
3.8
vehicle front
leading edge of the vehicle in its operational condition
Note 1 to entry: This would be the extreme front edge of any of the following - couplers, buffers, structures and
vehicle profile.
3.9
warning horn
warning device, generating an extended single lower frequency sound
Note 1 to entry: A warning horn may also be referred to as a ‘klaxon’, ‘makrophon’, or ‘typhon’ (similar to that
used in cars).
Note 2 to entry: The adjustment of a set of appropriate sound pressure levels enables the warning horn to be
used for different ranges including short-range, medium-range and long-range.
3.10
warning bell
medium-range warning device, generating a single impulse sound or series of recurring impulse sounds
3.11
soft bell
short-range warning device, generating a single impulse sound or series of recurring impulse sounds
Note 1 to entry: The soft bell is also referred to as a ‘gong’
3.12
whistle
short-range and medium-range audible warning device, generating a single higher frequency sound
3.13
A-weighted sound pressure level
L
pA
sound pressure level obtained by using the frequency weighting A, given by the following formula:

A
L 10⋅ lg  dB

where
L is the A-weighted sound pressure level in dB;

5 Requirements
5.1 General
Urban rail vehicles shall be equipped with a device or devices to emit up to three different types of
audible warning:
a) an audible warning signal to be used for long-range warning;
b) an audible warning signal to be used for medium-range warning, e.g. to avoid a collision with
another vehicle, obstacle or person(s);
c) an audible warning signal to be used for short-range warning, e.g. to notify persons nearby of the
presence of the vehicle.
NOTE 1 The audible warning a) is typically used over long distances up to 500 m; b) is used up to 50 m, and c)
is used up to 10 m.
Audible warning signals from urban rail vehicles should not conflict with other standard highway
sounds that are meant to be heard and understood by the public such as pedestrian crossings, railway
level crossings, lifting bridge/fire station sounds, emergency service sirens and road vehicle horns. The
requirements for eme
