General This European Standard defines the specific technical railway requirements for running of machines and other vehicles used for construction, maintenance and inspection of track, structures, track formation and fixed electric traction equipment. This European Standard applies to all rail bound machines and other vehicles - referred to as machines - running exclusively on the railway (utilising adhesion between the rail and wheels) 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 L. Additional requirements can apply for running on infrastructures with narrow gauge or broad gauge lines, lines of tramways, railways utilising other than adhesion between the rail and wheels, road-rail machines and underground infrastructures. This Standard covers the requirements for the keeping of safety and access of railway traffic, railway specific problems for running on different infrastructures in relation to necessary movements of the machine as a train and movements to reach work sites. The application of these requirements is the object of a verification procedure, which does not form part of this Standard. Access to railway infrastructures requires in all cases an access permit. Validity of the European Standard This European Standard applies to all machines, which are ordered after one year from the publication date of this standard.
