scope:

1.1 General
This European Standard deals with the significant hazards, hazardous situations and events by working with machines and other vehicles used for construction, maintenance and inspection of track, structures, track formation and fixed electric traction equipment according to prEN 14033-1:2007.
This European Standard applies to all railbound machines and other vehicles (including machines that in working position are partly supported on the ballast or the formation) - referred to as machines - working exclusively on the railway (utilising adhesion between the rail and rail wheels) and used for construction, maintenance and inspection of track, structures, infrastructure and fixed electric traction equipment.
This document deals with the common hazards, in normal circumstances, during transport, 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 (tropical or polar), 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 document. They can be subject of negotiation between manufacturer and the operator.
The common hazards dealt with 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 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 2 For such specific functions or hazards, the use of specific European Standards is recommended.
This document 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 established by a railway infrastructure manager;
. negotiations between the manufacturer and the machine operator for additional or alternative
requirements.
