BS EN 14033-1:2008

1.1 General This European Standard defines the technical running requirements to be met for machines and other vehicles used for construction, maintenance and inspection of track, structures, infrastructure 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 except machines which cannot be put into a train and their minimum mass is less than 9 t. This European Standard does not apply to demountable machines and to trailers less than 9 t tare weight. Different regulations are applicable for running on infrastructures with narrow gauge or broad gauge lines, lines of tramways, railways utilizing other than adhesion between the rail and rail wheels, road-rail machines and underground infrastructures. This European 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 access to railway infrastructures requires in all cases an access permit. 1.2 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.
