Highest Priority Issues
How Do You:
1) Know where to work
2) Know what work to do
3) Prioritize work
4) Monitor work progress, costing and material
5) Extend asset life whilst avoiding run to fail
6) Demonstrate competence to operate
7) Improve safety, reliability and Return on Investment

Looking into the FutureAnalysis and Forecasting
• Prioritize and plan work
• Identify areas of rapid deterioration or instable condition
• Evaluate work effectiveness
• Calculate quantitative measures of condition
• Do preventive maintenance by predicting failures
• Plan quarterly/monthly instead of annually
• Forecast when conditions will go out of tolerance
An analytic engine built to automatically turn large amounts of railway data into prioritized actions like:

Track Tolerance
• Use look up tables for defect thresholds for different track types
• Tables held in database
• Works on event sets
If track type = Class 1 then Gauge Threshold >57.6
If track type = Class 2 then Gauge Threshold >57.2
If track type = Class 3 then Gauge Threshold >56.8

Example: Forecast Tamping
• Forecasts where and when tamping required
• Optram automates 4 steps:– Aligns track measurements – Calculates historic quality indexes every 100m– Extrapolates when tamping is required– Presents results graphically
• Makes prediction over large railways practical

Example: Work Analysis
• Analyzes where tamping work was effective
• Optram automates 4 steps:– Aligns track measurements – Calculate a Track Quality Index for each survey– Determine where Track Quality improved– Compare improved Quality locations with recorded work
• Summarizes amount of– Productive and unproductive work– Unreported work
