Excess or deficit - what's the situation for existing track compared to the track template?
Are the shoulders and centre volumes comparable and what do the curves look like?
How much ballast is required to stabilise the track?
The Track Managers questions - the answer is in the ZeticaRail data, variable for curves & tangents
Ballast Volume Index - indicates overall excess or deficits relative to trackbed profile templates
Ballast Deficit Index - Identifies track sections with missing ballast
Ballast Excess Index - Identifies track sections with excess ballast
Four good points to consider -
The ZeticaRail's Track Drainage Index (TDI) is designed to highlight areas of poor runoff from the ballast toe, using data from our Hi-Speed laser system. Taking the FDL (Free Draining Layer) and ballast excess into account, TDI is an excellent tool for maintenance planning.
Tunnels, structures, platforms, rock cuttings, - all are accurately measured and compared with kinematic rolling stock clearances. Track centres and adjacent track can be a deliverable of this process, as are also road crossing angles and road heights relative to rail. Monitoring of trackside vegetation can be part of the survey.
Impressive and very useful results can be delivered by use of this mobile terrestrial laser system and Point Cloud data that can subsequently be generated. With use of identifying coloured highlights, clarity and dimensional capability obtainable from this process, it has markedly enhanced the planning process.
