BS EN 15746-4 This document specifies the technical requirements to minimize the specific railway hazards of selfpropelled roadrail machines-enceforward referred to as machines – and associated equipment,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. Where a machine is designed and intended for use on mainline and urban rail, the machine will comply with the most onerous conditions of EN 15746-1 and EN 15746-4. In all cases the machine will comply with the requirements set out in EN 15746-2.The requirements in this document amend those in EN 15746-1 as required for the use of the machine on urban railways.This document 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;-一moving and working while not on rails;-separate machines temporarily mounted on machines and associated equipment This document does not establish the additional requirements for the following:-operation subject to special rules, eg potentially explosive atmospheres; 一hazards due to natural causes, e.g earthquake, lightning, fooding;-working methods;-operation in severe working conditions requiring special measures, eg. extreme environmental conditions such as: freezing temperatures, high temperatures, corrosive environments, tropical environments, ontaminating environments, strong magnetic fields; – – hazards ocrring when used to handle suspended loads which may swing feely.For a road-rail machine it is assumed that an EU road permissible host vehicle will offer an accepted safety level for its designed basic functions before conversion. Unless explicitly stated otherwise in a particular clause this specific aspect is not dealt with in this European Standard.Other track construction and maintenance machines used on railway tracks are dealt with in other European Standards, see Annex B.BS EN 15746-4 pdf download.
