This European Standard deals with the technical requirements to minimize the specific railway hazards of railbound construction and maintenance machines henceforward referred to as machines, intended for use on urban rail. These hazards can arise during the commissioning, the operation and the maintenance of machines when carried out in accordance with the specification given by the manufacturer or his authorized representative. The requirements in this standard amend those in EN 14033-1 to -3 as required for the use of the machine on urban railways. Where a machine is designed and intended for use on mainline and urban rail, compliance with the most onerous conditions of EN 14033-1 and EN 14033-4 will be required. This European Standard does not apply to the following: the requirements for quality of the work or performance of the machine; the specific requirements established by the machine operator for the use of machines, which will be the subject of negotiation between the manufacturer and the Urban Rail Manager; moving and working whilst not on rails. This European Standard does not establish the additional requirements for the following: operation subject to special rules, e.g. potentially explosive atmospheres; hazards due to natural causes, e.g. earthquake, lightning, flooding; working methods; operation in severe working conditions requiring special measures, e.g. in tunnels or cuttings, extreme environmental conditions such as: freezing temperatures, high temperatures, corrosive environments, tropical environments, contaminating environments, strong magnetic fields; hazards occurring when used to handle suspended loads which may swing freely. Other track construction and maintenance machines used on railway tracks are dealt with in other European Standards, see Annex B.
