produce a drawing to show a cross section of trackincluding rails, sleepers and substructure.
• on the drawing identity the requirements for ballast depth andshow how the axel loading is distributed throughout theinfrastructure.
• interpret the engineering standards applied by the infrastructurecontroller, and produce a table showing examplesof Â
different design requirements applicable for line speeds and grossaxle tonnage.
• explain the gauging requirements of the track including theinterface with OLE and /or DC conductor in terms of railgeometry.
• explain the common failure modes associated with track geometrydefects.
