BS EN 14033-4:2019

This standard BS EN 14033-4:2019 Railway applications. Track. Railbound construction and maintenance machines is classified in these ICS categories:

• 93.100 Construction of railways
• 45.120 Equipment for railway/cableway construction and maintenance

1.1 General This document 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 systems. 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 rail systems. Where a machine is designed and intended for use on mainline and urban rail systems, compliance with the most onerous conditions of EN 14033-1 to ?3 and EN 14033-4 will be required. This document does not apply to the following: - requirements for quality of the work or performance of the machine; - machines moving and working whilst not on rails; - specific requirements established by the machine owner and/or operating company for the use of machines, which will be the subject of negotiation between the manufacturer and the Urban Rail Manager. This document does not establish 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 that may occur when a machine is 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. 1.2 Scope of urban rail systems Urban rail systems cover Urban Guided Transport systems (UGT) and might include other rail systems excluded from the scope of the Interoperability Directive 2008/57/EC (Article 1.3 (a) and (b))1. Urban Guided Transport systems (UGT), which cover metro, tram and light rail, are 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. Categories of urban rail systems include: - (I) Metros: UGT systems operated on their own right of way and segregated from general road and pedestrian traffic. They are consequently designed for operations in tunnel, viaducts or on surface level but with physical separation in such a way that inadvertent access is not possible. 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. - (II) Trams: UGT systems not segregated from general road and pedestrian traffic, which share their right of way with general road and/or pedestrian traffic and are therefore embedded in their relevant national road traffic legislation (highway codes and specific adaptations). - (III) Light Rail: Light Rail is defined as a UGT system operated in parts of the system not segregated from general road and pedestrian traffic, and in parts of the system with segregated right-of-way. The segregation may include some sections of line where inadvertent access is not possible. - (IV) Local rail systems which 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.
