1.1 General
This European Standard specifies the significant hazards, hazardous situations and
events, common to rail bound machines and arising due to the adaptation for their
use on railways. These machines are intended for construction, maintenance and inspection
of track, structures, infrastructure and fixed electric traction equipment, when they
are used as intended and under conditions of misuse which are reasonably foreseeable
by the manufacturer, see Clause 4.
This European Standard applies to railbound machines and other vehicles - referred
to as machines - working exclusively on the railway (utilising friction adhesion between
the rail and rail wheels) but including machines that in working position are partly
supported on the ballast or the formation and used for construction, maintenance and
inspection of track, structures, infrastructure and fixed electric traction equipment.
This European Standard applies to machines that are intended to operate signalling
and control systems. Other similar machines are dealt with in other European Standards,
see Annex D.
This European Standard specifies the common hazards, in normal circumstances, during
running, assembly and installation, commissioning, use (including setting, programming,
and process changeover), operation, cleaning, fault finding, maintenance and de-commissioning
of the machines. Additional safety measures can be required by exceptional circumstances,
such as extreme ambient temperatures (less than – 20 °C or greater than + 40 °C),
highly corrosive or contaminating environment; e.g. due to the presence of chemicals,
and potentially explosive atmospheres. Air pressure caused by the passing of high-speed
trains at more than 190 km/h is also not dealt with.
NOTE 1 Specific measures for exceptional circumstances are not dealt with in this European
Standard. The specific measures for exceptional circumstances introduced by a railway
infrastructure manager and requirements introduced by the manufacturer and/or machine
operator as referred to in the scope are not dealt with in this European Standard.
When such additional measures are necessary, they should be agreed between the manufacturer
and the machine operator. The manufacturer will be responsible for compliance with
the Directive(s) concerned independent of this European Standard for additional hazards
created by any additional or alternative requirements.
NOTE 2 This European Standard deals only with the additional hazards from the adaptation
of a machine for its use on rail. Other standards specific to the particular machine
as far as available will need to be used in addition to this European Standard to
give the complete requirements.
The common hazards specified include the general hazards presented by the machines,
and also the hazards presented by the following specific machine functions, common
to two or more machine types:
-
— ballast excavation, ballast cleaning, ballast regulating, ballast consolidating;
-
— tamping;
-
— track renewal;
-
— craning;
-
— maintenance of the components of the infrastructure;
during commissioning, use, maintenance and servicing.
This European Standard does not deal comprehensively with specific machine functions
other than the common functions listed in the previous paragraph, or with all possible
hazards presented by complete machines or by the combination of functions.
NOTE 3 For such specific functions or hazards, the use of specific European Standards is
recommended.
This European Standard does not deal with:
-
— requirements with regard to the quality of work and the performance of the machine;
-
— machines that utilise the catenary for traction purposes;
-
— specific requirements introduced by a railway infrastructure manager;
-
— additional or alternative requirements introduced by the manufacturer and/or operator.
