DANSK DSF/PREN 13231-1 PDF

This European Standard specifies the minimum technical requirements and the tolerances for the acceptance of works on ballasted track situated on plain line and on switches and crossings and rail expansion devices, as part of the track, for 1435 mm and wider track gauge railways, concerning construction of new track, track renewal and track maintenance. More particularly this standard gives the requirements for the documentation of work parameters, for the tolerances for relative track geometry and absolute track position and for the acceptance procedures. This standard does not deal with contractual and legal aspects and it does not cover either works related to reprofiling the railhead nor the associated measurements, except for some measurements related to safety, since these works are covered by other parts of EN 13231 series. Related works, e.g. platform reconstruction, formation, drainage, level crossings are not covered by this standard.
